The development of new sintering techniques, such as field assisted sintering,
spark plasma sintering, flash sintering, laser flash sintering, and cold
sintering, has led to material consolidation at significantly lower
temperatures and shorter times. Microstructure formation and corresponding
structure-property relations of materials consolidated using these new

structure, local defect distribution, space charges, anisotropy of transport
processes at interfaces, and texture enables new applications in various fields
of structural and functional materials.

Powder and Wire Metallurgy (PW/M) is a commonplace fabrication and processing
method for high throughput part production in industrial settings.
Additionally, PW/M fabrication and processing advancement also is an essential
counterpart to the advancement of additive manufacturing (AM) with powder-based
AM methods. Novel and intensive research is ongoing in innovative, traditional,
and emerging magnetic materials and functional materials; however, the
practical application is limited by the ability to form these typically brittle
materials into the shapes that are designed for the applications. At this time,
advanced powder synthesis and processing, including additive manufacturing, can
provide a way to form these materials into final shapes for applications.

Most industrial applications such as the aerospace, automobile, biomedical and
defense areas need materials that must operate in increasingly extreme and
complex environments. Usually no single existing alloy can meet all the
requirements of a desired system component. Thus, the successful design and
processing of a gradual change in composition and microstructure, and therefore
properties, over the whole material is gaining considerable attention in
materials science and engineering. Graded materials, coatings and claddings
allow for unique combinations of properties to enable various harsh
environment, functional and structural applications. In practice, functionally
graded materials (FGMs) are often susceptible to processing defects linked to
prohibitively time-consuming, empirical process development without the ability
to predictively determine and/or rapidly screen experimentally viable pathways
(composition and process parameters) to optimize their production. Due to these
limitations, the actual performance of FGMs, relative to conventional parts,
remains to be validated and optimized. This symposium focuses on all aspects of
the science and technology, from fundamental science to industrial
applications, that will enable control of the microstructure and properties of
graded materials coatings and claddings, including: thermodynamic, kinetic,
property, and microstructure evolution simulations; rapid processing; in situ
characterization; and understanding defect formation.
Many types of gradient systems are of interest, including from one alloy
composition to another, from metals to ceramics, and from intermetallics to
metals. Advances in coating technologies, new compositions of coatings, and
advanced manufacturing techniques are of interest. Specific topics include, but
are not limited to:
• Fundamental issues and underlying mechanisms in processing FGMs, coatings,
and claddings
• Development and demonstration of computational-experimental platforms to
produce viable graded components ready for various types of advanced testing

Ultrafine-grained and heterostructured (UFGH) materials have been drawing great
attention from the materials research community because of their superior
mechanical and functional properties. In practice, heterostructures involving
an architecture microstructure, such as coarse-grained colonies dispersed in
fine-grained matrix, multi-length scale twins packed in predetermined fashion,
impregnation of transformational phases into non-transformational phases, etc.,
can produce outstanding combinations of mechanical properties that are not
accessible to materials having homogeneous microstructure. Formation of
heterostructures enables a new perspective to further enhance the properties of
UFG materials produced by severe plastic deformation and other processing
methods. Heterostructured materials can be produced using industrial facilities
for large-scale production at low cost. A continuous effort has been made in
the research field dealing with processing of UFGH materials and a significant
number of studies have been conducted to understand the underlying mechanisms
that control the mechanical behaviors of such materials. This symposium focuses

Metals powders have unique properties that make them useful for a wide range of
applications, in which powder is either the final product or the feedstock. The
production of powders from many metals is often non-trivial and/or energy/cost
intensive. Furthermore, while being in powder form enables new processing
techniques and material properties, it also presents new processing challenges
in safety, purity, handling, flowability, etc. There is continual need for
further understanding the underlying science of both synthesis and processing
in order to improve optimization of the applications that utilize these
materials. Furthermore, recent advances in related sciences and modeling
capabilities have enabled new pathways and techniques to realize these goals.

fabrication of ceramics, glasses, advanced concretes, and ceramic-metal
composites. Recent years, the hybrids of ceramic and metallic materials have
received plenty of interdisciplinary inspirations and achievements in material
processes and functional applications including ionic conductors, catalysis,
energy conversion and storage, superconductors, semiconductor, filtrations,
etc.
Topics of this symposium will cover, but not limited to:
• Silicates, oxides, and non-oxide ceramics and glasses
• Synthesis, characterization, modeling, and simulation of ceramic materials
• Design and control of ceramic microstructure and properties
• Ceramic powders and processing
• Catalyst and catalyst support materials
• Fundamental understanding of ceramic materials and processes.
• Novel methods, techniques, and instruments used to characterize ceramics and
glasses.
• Bioceramics, electronic, magnetic ceramics, and applications
• Surface treatment and ceramic thin films, membranes, and coatings
• Porous ceramic materials
• Hybrid systems of ceramic, metal, and/or polymer composites
• Ceramics used for extreme environments
• Metallurgical byproducts for ceramic manufacturing
In the complex web of energy resource, production, storage, use, and
efficiency, materials play a critical role as diverse and far-reaching as
energy itself. Powder materials are part of the fundamental science and
technology underlying the production of energy, including both conventional and
renewable energy sources. Increasing demand for energy and the public’s desire
to enhance environmental quality all point to the need for better and newer
powder materials.
This symposium will cover powder material issues related to energy. It will
consider all aspects of powder material processing and property studies with
energy applications as the main objective. It includes powder synthesis,
forming (including additive manufacturing), sintering, and property evaluation.
Powder materials that can deliver outstanding harsh environment properties are
especially of high interest. The symposium covers advances in theory, modeling,
and computation while in parallel developing cutting-edge experimental
techniques and approaches to understand and characterize powder materials in
demanding conditions. Both theory and modeling and experimental efforts in
powder materials synthesis, processing, characterization, and performance
evaluation will be covered.
Additive manufacturing comprises a breadth of processes, which have significant
economic potential and technical challenges. Significant resources have been
committed to laser powder bed fusion and electron beam powder bed fusion
processes. However, additive processes which produce green components and
require consolidation processes such as sintering and HIP eliminate many short
comings such as slow build rates, residual stress and print support
structures. In addition, the green part additive technologies build on
existing process technology from the powder materials and ceramics, which
enable the additive processing of non-weldable materials. These processes
include but are not limited to: binder jetting, material extrusion, filament
process, nano-Inkjet printing and selective laser sintering. However, these
processes introduce other challenges such as: feedstock development, alloy
design, depowdering, powder recycling, binder design, debinding, full
consolidation, microstructural development, sintering distortion, sintering
support structure design. This symposium will explore the interrelationships
between the various aspects on the process variables, properties, application
performance, economics and functionality of these non-beam additive processes.
Titanium and titanium alloys are used in many demanding applications in
aerospace, automotive, biomedical and terrestrial systems because of their
excellent combination of mechanical properties and corrosion resistance.
However, titanium alloys are excluded from many applications because of their
high cost- a result of an energy intensive extraction process and complex
fabrication sequence to mill products. This is particularly true in the cost
obsessed automobile industry; albeit some in-roads are now being made even into
the family car.
In the proposed six-session symposium, papers addressing all aspects of cost
reduction in titanium and its alloys will be presented, and proceedings will be
published. The various segments of titanium technology to be covered will
include, but not be limited to: extraction (with emphasis on innovative and low
cost Kroll approaches) new lower cost alloys, creative melting including cold
hearth approaches, near net shape techniques (including powder metallurgy
variants such as near net shapes, spraying, laser forming, and casting
approaches), additive manufacturing, biomedical applications,
processing/fabrication advances such as warm drawing, extrusion, superplastic
forming (also in combination with diffusion bonding), high speed machining and
knowledge based processing with emphasis on computer aided approaches, better
process control including enhanced inspection methods, and creative designs
such as functionally graded materials, porous alloys and infiltrated concepts.
