THETRACKS
The program is designed to offer a wide range
of disciplines on Advanced Materials Technology
including the following:
TRACK
1
Lightweight Materials:
In the last few years, lightweight materials with improvements
in durability, energy efficiency and performance have
received considerable attention in numerous sectors
including aerospace, transportation, energy and biomedical
technology. Lightweight materials may generally be classified
into three main categories: metal alloys, composites (MMC,
PMC and CMC), polymers and ceramics. While the growing
demand for lightweight materials is unquestionable, there
are different crucial factors in this technology need more
improvements in areas such as processing cost, integrity,
durability, reproducibility and safety. This session will
address the state-of-the-art research activities related to this
field.
TRACK
2
Advanced Materials for Water and Energy
Applications:
Recently, water treatments and energy efficiency have been
receiving more attention than ever before. It is well-known that
materials developments play predominant roles in improving
the sustainability of these two sectors. Developments in
advanced materials related to membranes and renewable
energy are just examples of this strong relationship. This
session will focus on the recent materials developments
targeting water and energy applications.

Advanced Materials for Extreme
Conditions:
The growing demands for developing new materials that
perform effectively under extreme conditions, such as
aggressive chemical and radioactive environments, high
temperature and stress, can be considered the driving
force behind nowadays materials revolution. Developed
materials for harsh conditions have to meet, also, the
social demands such as safety , energy-efficiency,
reliability and at the same time, with affordable cost. This
session will highlight materials developments relevant to
this field.
TRACK
4
Advanced Materials Processing
Technologies:
Despite the diversity in nowadays materials, they
are fundamentally having similar principles in areas
such as thermodynamic stability, mass transport,
phase transformation and materials structure from
the atomic to microscopic level. Materials processing
plays a central and critical role in defining the resulted
microstructure and, consequently, the final mechanical,
physical and chemical properties of the processed
materials. Therefore, accurate prediction of the inprocess microstructural evolution is essential to
control the resulted microstructure, to understand the
relationships between processing conditions and the
final microstructure and to adjust processing conditions
to produce a material with the desired properties. The
clear dependence of a certain material property on
specific processing conditions is not only limited to
the conventional materials but for the new and future
materials as well. This session will address the stateof-the-art research activities in materials processing,
microstructural control and performance integrity.

ABSTRACT:
Currently new and enhanced steels are required to meet a broad range of societal needs including, as examples,
more efficient transportation systems, improved and expanded energy production systems, and infrastructure
development and redevelopment projects. As a result, multiple innovations in the steel industry have been
realized to support the needs for economic solutions for these critical applications. This presentation will
include an assessment of research innovations in the global steel industry as well as specific selected
research examples chosen to illustrate the broad range of developments that have evolved recently leading to
new products. While corporate research programs are important, emphasis here will be placed on industry/
university partnerships and their importance to the steel industry. Information is drawn from the research of
the Advanced Steel Processing and Products Research Center, an industry/university cooperative research
center currently in its 31st year of operation at the Colorado School of Mines. Specific research examples will
include sheet, plate and bar steels. For example, newly developed advanced high strength sheet steels (AHSS)
with excellent formability that have evolved particularly for automotive applications will be highlighted. These
new high-strength steels enable vehicle weight reduction to improve fuel economy and lead to enhanced crash
performance and passenger safety. As a second example, research on high-strength pipeline steels will be used
to illustrate how the application of advanced analytical techniques (e.g. electron back scattered diffraction –
EBSD) has provided enhanced understanding of the fundamental factors which control strength and toughness
in plate steels used to fabricate high strength pipe. In addition, an assessment of future research opportunities
for the steel industry will be presented.

Title Presentation: Severe Plastic Deformation: An Effective Approach
for Grain Refinement, Improved Strength and Enhamced Ductility
BIOGRAPHY
I graduated with a Bachelor degree from Mechanical Design and Production Department
from the College of Engineering, Cairo University with Distinction with honor in 1991. I
finished My Master of Science degree in Computer Aided Design and Optimization of Gears
in 1994 from the same Department. I then joined Drexel University in Philadelphia PA, USA in
1994 in the Department of Materials Science where I was awarded my Ph.D degree in 1998. I
have received the following awards: • First rank award for Research Excellence from College
of Engineering, King Saud University, 2012. • Highly Cited Author Award, 2003, THOMSON ISI.
• Best Academic achievement “Harry Roger award”,1998, Drexel University. • Best Academic
Achievement, 1993, from the Engineering Syndicate in Cairo, Egypt.
ABSTRACT:
Two basic and complementary approaches have been developed for the synthesis of ultrafine
grained (UFG) materials and these are known as the ‘‘bottom-up’’ and the ‘‘top-down’’ approaches.
In the ‘‘bottom-up’’ approach, UFG materials are fabricated by assembling individual atoms or by
consolidating nano-particulate solids. The ‘‘top-down’’ approach is different because it is dependent
upon taking a bulk solid with a relatively coarse grain size and processing the solid to produce a
UFG microstructure through heavy straining or shock loading. In order to convert a coarse-grained
solid into a material with ultrafine grains, it is necessary both to impose an exceptionally high strain
in order to introduce a high density of dislocations and for these dislocations to subsequently rearrange to form an array of grain boundaries. The potential of improving mechanical properties by
reducing the grain size to the nanostructured regime has been aggressively addressed, and is the
focus of this presentation. The work, currently presented, addresses cryomilling and subsequent
consolidation of aluminum alloys powders ( 99.7 Al, 6061 and 2024 AA) as one technique that
represents the bottom-up approach. Of the top-down approach techniques investigated are the
equal channel angular pressing (ECAP), high pressure torsion (HPT), friction stir processing (FSP),
cryogenic shock loading, accumulative roll bonding (ARB) and rotary swaging (RS). The previous
processing techniques were employed on a group of aluminum alloys (6082, 5083, 1050 AA) and
a group of titanium alloys (CP Ti, Ti54M AND 10-2-3 Ti alloy). All of these procedures are capable
of introducing large plastic straining and significant microstructural refinement in bulk crystalline
solids. The results focus on documenting the evolution of mechanical properties, microstructure
and texture.

Dr. Marc Leparoux
Group Leader Nanopowder & Composites
Swiss Federal Laboratories for Materials Sciences and Technology (EMPA) Title Presentation: Light Weight Improved Metal-Composites Reinforced with
Nanoparticulate Materials
BIOGRAPHY
Marc Leparoux studied Physics and Chemistry of Materials in Rennes (France). He obtained his PhD in Applied
Sciences in 1995 in Orléans (France) on the chemical vapor synthesis of Boron Nitride based interphases
for SiC/SiC ceramic composites. The PhD work was performed at CNRS together with an industrial partner,
the Snecma Group. He then joined the Fraunhofer Institute for Materials and Laser Technologies in Dresden
(Germany) where he was in charge of the laser assisted chemical vapor deposition for coating fibers to be used
in composite materials. In parallel, he developed infrared spectroscopy techniques for monitoring gas phase
processes. He joined Empa in Switzerland in 2001 where he initiated the nanoparticle thermal plasma synthesis
activities. He then built a unique inductively coupled thermal plasma reactor allowing the in-situ characterization
of the nanoparticle synthesis. The facility has been used for producing a large variety of different materials like
carbides (SiC, TiC, WC, TaC, ZrC), carbonitrides (TiCN), oxides (Al2O3) and also some metallic materials like
Cu, Si, NiTi. Beside the synthesis of nanoparticles, the reactor can also be used for spheroidizing microscale
particles or functionalizing powders. With these activities, Marc Leparoux is involved in a lot of large projects
in Europe on batteries and composites. In 2006, he started in parallel his activities on metal matrix composite
reinforced with the nanoparticles he produced. He reported among the best mechanical strengths for aluminum
alloys reinforced with nanoparticulate materials. In this framework, a project together with KACST has been
launched. He is leading officially the Group Nanoparticles and Nanocomposites since more than 7 years.
ABSTRACT:
A simple powder metallurgy approach is reported for producing metal matrix composites reinforced with
nanoparticles showing outstanding mechanical strength and hardness. The metal and nano-reinforcement
powders are mixed in a high energy ball mill and the resulting blends are hot compacted using a uniaxial
press. High energy ball milling was indeed successful in dispersing different nanoparticulate materials into
an AlMg5 alloy matrix. Carbon nanotubes (CNT) as well as Al2O3 or SiC nanoparticulate materials could be
thus dispersed up to above 10 vol%. Hardness improvements by a factor of 4 - from 70 to 275 HV20 - could be
achieved for the as pressed composites with 5 vol% CNT. The ultimate tensile strength (UTS) increased from
290 MPa for raw AlMg5 to 700 and 720 MPa with 1 vol% alumina nanofibers and 0.5 vol% CNT respectively.
However these high strength composites dramatically suffered from low ductility. Typically 1 % of elongation at
rupture could be measured in the best cases. The milling conditions like the process control agent, the milling
time and the mill geometry have then been carefully investigated and their optimization allowed reaching a
reasonable compromise between high strength and high ductility. For instance the composite AlMg5-0.5 vol%
nanoAl2O3 (mean diameter 20 nm) shows the following mechanical properties: 500 MPa ultimate strength,
475 MPa yield strength and an elongation at rupture around 10%. A linear regression could be drawn between
the strength and the strain of the composites reinforced with less than 1 vol% of alumina nanoparticles. These
mechanical properties are comparable or even better than those reported for commercial available alloys for
which a costly special heat or work hardening treatment is required.

ABSTRACT:
The talk will focus on strategies that we have been developing to improve electrode material
performance in capacitive energy storage devices, including conventional pseudocapacitors,
hybrid supercapacitors, and microfabricated supercapacitors. The talk will cover the
development of organic and inorganic electrodes that offer both macroporosity and
mesoporosity using in-situ nucleation on current collectors. The resultant morphologies of
such electrodes facilitate electrolyte permeation, reduce device resistance, and provide large
surface areas for faster reaction kinetics at the electrode surface, thereby increasing device
capacitance. Development of negative electrode materials for the fabrication of hybrid and
asymmetric capacitive devices, which work at higher voltage, will also be covered. Finally,
recent development in flexible and microfabricated supercapacitors for self-powered device
applications will be discussed.

Title Presentation: Inorganic Membranes for Water Filtration and Desalination:
Opportunities and Challenges
BIOGRAPHY
Dr Tahar Laoui is Professor of Materials & Manufacturing Engineering in Mechanical Engineering
Dept. at King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, Saudi Arabia. He
received his PhD from the University of Washington, Seattle, USA in 1990. Keywords describing
his research interests include processing of advanced materials and nanomaterials with a focus
on nanocomposites and how to enhance uniform dispersion of nanoparticles within the matrix as
well as to minimize grain growth for powder mixtures subjected to sintering during consolidation
by using non-conventional techniques such as spark plasma sintering. For the past few years,
he conducted research in joint collaboration with colleagues from Mechanical Engineering Dept.
at MIT, USA, and Chemical Engineering Dept. at KFUPM on the development of inorganic and
composite membranes for water treatment and water desalination by exploring techniques to
synthesize and characterize the transport of water and ions through macro- and nano-structured
materials such as zeolites, alumina-based ceramics, activated carbon and graphene. He is a
Fellow of The Institute of Materials, Minerals and Mining, member of editorial board of Membranes
journal, and served as a reviewer/member of the review committee for many journals and national/
international conferences. He has published over 120 refereed journal & conference papers. ABSTRACT:
Clean water has become an important commodity to due to growing world population, increasing
industrial plants, and depletion of some conventional fresh water resources such as lakes, rivers
and groundwater. Therefore, water filtration/purification or water reuse and desalination have
emerged as keys solutions to alleviate the water shortage problem. Among the various technologies
used to produce drinkable water, membrane based technologies are increasingly adopted, in which
membranes are made from polymeric materials (commercially dominant due to its maturity),
ceramics and composites. However, polymeric membranes suffer from low flux, excessive fouling,
and low resistance to chlorine, while inorganic/ceramic membranes offer potentially high permeate
flux, high salt rejection and enhanced fouling resistance. They are particularly suitable for processes
with high temperatures and harsh chemical environments due to their high thermal, chemical and
mechanical stability. On the other hand, the performance of ceramic membranes is dictated by their
morphology including pore size, shape, density, and distribution and surface characteristics, which
are crucial to control during their fabrication. In this presentation, the opportunities offered by
inorganic membranes for use in water treatment and desalination will be highlighted along with the
associated challenges and difficulties. The research activities taking place at King Fahd University
of Petroleum & Minerals (KFUPM) in this area, in collaboration with other universities such as
Massachusetts Institute of Technology (MIT), will be discussed. It is worth mentioning that some
of this research is supported by King Abdulaziz City for Science and Technology (KACST), as part
of the National Science, Technology and Innovation Plan, which gratefully acknowledged.

ABSTRACT:
The invention of friction stir welding involved a strong technological pull and the initial phase
involved adoption of this innovative technology for solid state joining of ‘non-weldable’ high
strength aluminium alloys. Currently the spectrum of applications is quite wide. This talk will
present an overview of the path of progress in the last twenty years. Illustrative examples will
be presented to provide linkages between the current status and challenges for the future
growth. Particular emphasis will be on high strength aluminium alloys, magnesium alloys,
titanium alloys and steels. Emerging potential for dissimilar alloys and dissimilar materials
will be highlighted in relationship with the fundamental metallurgical issues and mechanical
approaches. Hybrid processes that decouple the heat input from material flow are being
pursued to either overcome the limitations or expand the process domain. A very short
overview on friction stir processing will be included to capture the potential of derivative
processes.

ABSTRACT:
The surface of materials often interacts with the environment, which may be a gas (e.g. air) or a liquid (e.g.
water). This interaction can be detrimental to the material and cause its degradation by corrosion. The
degradation of materials in corrosive environments leads to macroscopic manifestations, but the mechanisms
must be understood at the atom or nanometer scale. In this lecture I will review various aspects related to the
role of the surface structure and composition of alloys on corrosion, and the key issue of corrosion protection
by surface oxide layers (passive films).
The following points will be addressed:
- The effect of grain boundaries and grain boundary structure on localized dissolution or passivation
- The early stages of interaction of metal surfaces with water
- The composition and structure of passive oxide films on metals and the role of alloying elements
The data that will be presented have been obtained on different metals and alloys, including stainless steels
and aluminium alloys, using advanced surface analytical techniques, X-ray photoelectron spectroscopy (XPS),
time of flight secondary ion mass spectrometry (ToF-SIMS), scanning tunneling microscopy (STM), combined
with electrochemical methods.

ABSTRACT:
Nanomaterials, especially rare earth oxide materials (nano to micro size particles), have been
shown to effectively protect stainless steels and other alloys from high temperature degradation.
However, recently we discovered the unique antioxidant properties of these rare earth oxide
nanoparticles, where it protects mammalian cells against damage caused by increased reactive
oxygen or nitrogen species, and has been shown to act as effective superoxide dismutase mimetic
in vitro. The redox ability of rare earth oxides has been used in a wide range of applications such
as three way catalysis, oxygen buffer systems, sensors and corrosion prevention. While these
nanostructures have been widely used in many inorganic applications, their role in biology as
catalyst is not explored fully. This presentation will provide a brief overview of the applications of
these unique nanostructures in treatment of disorders caused by reactive oxygen species (ROS).
It was found that the redox kinetics of regenerative oxide nanoparticles can be controlled with the
type of medium and their implications in nanobiomedicine is presented.

Title Presentation: Thermoset Based Lightweight Construction Materials
BIOGRAPHY
Dr. Christian Dreyer, born 1971 in Idar-Oberstein, Germany, obtained his Diploma degree in Chemistry from the
Technical University of Kaiserslautern, Germany, in 1996 with a thesis about Triazine Containing Dendrimers.
He obtained a further degree in Analytics and Spectroscopy from the University of Leipzig, Germany in 1999
before receiving his Ph.D. in Polymer Chemistry from the Brandenburg University of Technology of Cottbus,

the Fraunhofer Institute for Reliability and Microintegration in Teltow. In 2002 he worked as a visiting scientist at
the Clemson University, SC, USA. Dr. Dreyer joined in 2006 the automotive supplier LEONI, Nuremberg, Germany
as head of the chemical laboratory of the Central Research and Development Department. Since 2011 he is
Deputy Director of the Fraunhofer Research Institution for Polymeric Materials and Composites, Teltow. His
research interests are development, synthesis, characterization and processing of thermosets for light weight
construction and (integrated) optical applications. Dr. Dreyer is also responsible for alternative curing methods
of thermosetting resins; including UV-curing, IR-Curing, E-Beam and Microwave-Technology. Christian Dreyer is
author or coauthor of 75 papers and has 34 patents.
ABSTRACT:
Thermoset based lightweight construction materials are used in many industries due to their high (thermo)
mechanical performance. However, the cross-linked structure of the thermosets, which is responsible for
their good performance, is not always an advantage. Conventional recycling and repair methods are often not
applicable for thermosetting polymers. The most frequently used recycling and disposal methods for thermoset
composites, which are landfilling, burning or grinding into a raw powder, are not efficient. The state-of-the-art
repair methods are mostly based on removing the damaged area by grinding or milling, followed by sticking new
layers even if the composite is only de-laminated. In the case of a delamination, it would be more efficient to
remove the dam-aged matrix without damaging the endless fibers. For this reason Fraunhofer PYCO developed
a simple, efficient and quick recycling and repair method for cyanate- and cyanate-epoxide-based composites.
Cyanates are formed via cyclotrimerization reaction from at least difunctional cyanate monomers, showing
high glass transition temperatures, thermal sta¬bility and high me-chanical strength as well as a lot of other
excellent properties. Furthermore, cyanates can react with a variety of compounds, e.g. epoxides, giving the
possibility to produce polymers with tailor-made properties, for example for applica¬tions acquiring fast curing
or curing at low temperatures. Regarding to the recycling process, the matrix resin can be decomposed and
fibers with good properties could be regained. The recycling of cyanate esters can be done under rela¬tively
mild conditions (from room temperature up to 190 °C) using a special class of agents, producing triazinecontaining structures, as well as phenols. The particular recy-cling product composition and the recycling
time depend on the specific formu¬lation and on the particular recycling agent. Recycling times below 1 h
are feasible. Furthermore, the decomposed matrix can be reused in the preparation of new thermo¬sets, e.g.
polyurethanes, epoxides or polyacrylates with glass transition temperatures up to 130 °C. Concerning repair,
the matrix could be decomposed in a well-defined area and the un-covered fibers could be impregnated with
new resin. By choosing the right agent and reimpregnation resin, the mechanical performance of the repaired
composite is compar-able to the performance of a new part.

ABSTRACT:
The ability to deposit microstructured coatings by the High Velocity Oxy-fuel spraying process
is well established in the area of thermal barrier coatings for the aerospace industry, however,
the application of this technology to the oil and gas industry is relatively new. Research
on the use of nanostructured materials indicates that certain properties such as strength,
hardness and fracture toughness can be enhanced if a nanostructure was used in place of
the microstructured material but the ability to deposit nanostructured coatings is relatively
new and posses a challenge. This presentation will review the application of the HVOF
coating technique and important parameters used to produce nanostructured coatings. A
comparison of the wear resistant behaviour of microstructured and nanostructured coatings
based on the WC-Co composition deposited on C-Mn steel substrates will be presented. 28 The 3rd Saudi International Conference on Advanced Materials Technology 2015

leader in the Applied Optics Laboratory headed by R. P. Salathé, at EPFL focussing on laser induced localized
chemical vapour deposition processes and improving the technologies for production of near field optical
probes (SNOM tips). Industrial experience in an electrochemical company was acquired from 1995 -1997 as
dental section manager at Gramm Technik (Germany). From 1997 until 2009 he carried out research on Laser
Micro-Processing, surface coatings, and Focused Electron Beam Induced Processing (FEBIP). Since 1997 he is
teaching on the bachelor, master, and PhD level in micro-engineering and materials sciences at EPFL. In 2009
he became head of the Laboratory of Advanced Materials Processing at Empa, Swiss Federal Laboratories for
Materials Sciences and Technology, continuing teaching at EPFL. He is author or co-author of more than 111
peer reviewed journal papers and inventor or co-inventor of half a dozen patents.
ABSTRACT:
Laser beams as well as charged particle beams (electrons, ions) entered into industrial processing for carrying
out specific tasks of local energy input. From very small energy input, i.e. changing solubility of so called
resists in microelectronics, through melting materials in welding processes, to high energy input in materials
evaporation, or if applied in very short pulses even very rapid ablation of materials. Both, removal and deposition
of materials by these local energy sources have been developed. Here we focus on generative processes, i.e.
deposition of materials either from solid, liquid, or gaseous precursors for growing structures. Limitations
such as processing speed, resolution, and materials quality will be presented and compared. Focused electron
beam induced deposition of pure metal nanostructures to laser induced microstructures will be presented
and discussed with impact on the generative processes starting from larger materials precursors such as
micrometric sized powders. Focused electron beam induced etching and deposition are industrial processes
for semiconductor mask repair. The electron beams have replaced Focused Ion Beams due to dramatically
lower interaction with the substrate to be repaired, the very precious lithography masks. The latter are key
elements for massive parallel mass production of chips in semiconductor industry and since recently also in
mobile electronics industry. Laser direct writing by LCVD or by laser deposition from electrolytic metal solutions
allow growing structures with relatively small growth rates, due to limited metal precursor supply. Laser welding
processes on the other hand are not limited by materials supply, but still speed limited for obtaining high
quality welds. These two process limitations will remain the challenges in modern direct laser melting additive
manufacturing processes. Taking the case that the materials supply is sufficient, the heat management, i.e.
reasonable heating rates to avoid excessive evaporation, key hole formation or conduction melting, and microstructure tailored cooling, have to be optimized in high quality high reliability laser generative processing.
Productivity enhancement can only be achieved by selection or synthesis of ideal materials destinated for
additive manufacturing.
