Titanium and titanium-based alloys have indisputably contributed to many
technological advancements of the modern society owing to their unique
structural properties combined with a low density and in-vivo biocompatibility.
Today these alloy systems are commercially used in myriad applications ranging
from the hot-sections of an aero-engine to structural applications at cryogenic
temperatures, ballistic shield components at room temperatures, orthopedic
implants, etc. Large tonnage commercial usage of titanium and its alloy systems
for such a diverse range of sensitive and safety-critical engineering
applications is rooted in the detailed understanding of the underlying
structure-property-processing relationships based on extensive research
spanning over the last fifty years.
To deliberate upon some of these issues, the signature symposium hosted yearly
by the Titanium Committee aims to serve as a forum for titanium experts and
researchers from all over the world. It has been a well-received international
platform for scientists, engineers, and technologists from industry, academia,
and research laboratories to exchange ideas and share the latest progress on
the state-of-the-art in processing-microstructure-property co-relation within
titanium and titanium-based alloys. The symposium covers all aspects of
physical and mechanical metallurgy of titanium and titanium alloys including
novel processing techniques, recent product development, new alloy design
approaches, microstructure exploration, and performance evaluation. The topics
of choice include, but are not limited to:
• Titanium and titanium alloys, including near alpha alloys, alpha+beta alloys,
metastable beta alloys, intermetallic alloys, titanium aluminides, and titanium
matrix composites.
• Alloy design approaches to novel commercial applications.
• Processing of titanium and titanium alloys using advanced techniques.
• Additive manufacturing of titanium-based alloys and their structure-property
relationships
• Phase transformations and microstructural evolution in titanium and titanium
alloys.
• Dynamic mechanical behavior and performance of titanium and titanium alloys.
• Deformation mechanisms within Titanium based alloys at various temperatures
and loading conditions.
• Translating novel processing routes for titanium-based alloys from
laboratory-scale to commercial scale.
This symposium is being organized on the occasion of Professor Dipankar
Banerjee’s 70th birthday to celebrate his seminal contributions and profound
impact on the field of Titanium physical metallurgy. It brings together leading
experts from across the world working on various aspects of titanium alloys
many of whom are his close friends and collaborators. The scope of the
symposium broadly encompasses all aspects of titanium and titanium-based
intermetallics including innovative processing routes, advanced
characterization techniques, novel computational modelling approaches etc. The
symposium will have special emphasis on advanced electron microscopy for
assessing the structure-property-processing correlation within titanium-based
alloys and intermetallics, with sessions also dedicated to evaluating phase
transformation pathways and deformation mechanisms, domains which have
immensely benefitted from Professor Banerjee’s research contributions. These
will include phenomena operating across multiple orders of length scales
extending from atomic-level to ingot- scale, across a wide range of
temperatures and loading rates. Please note that participation to this
symposium is by invitation only.
Titanium (Ti) and its alloys are expanding in use within the aerospace,
automotive, biomedical, and sports and recreation industries due to their
exceptional properties, such as specific strength, biocompatibility, and
corrosion resistance. This symposium serves as an international forum for
scientists, engineers, and technologists to discuss and exchange ideas on
• composition and texture effects on plasticity and fatigue of titanium alloys
for aerospace applications
• evaluating additive manufacturing for fatigue-critical applications in
aerospace
• revisiting hydrogen effects in titanium in anticipation of a hydrogen economy
• metastable and stress-induced phase transformations in beta-stabilized
titanium alloys for biomedical application
• novel functional properties in metastable beta-stabilized titanium alloys
• state of ICMSE/material genomics for titanium
We intend to bring together individuals from industry, academia, and research
laboratories to present advances in these areas and identify issues and
phenomena with overarching impact. Presentations dealing with processing,
characterization, mechanical behavior, interfaces, modeling, life prediction,
product development, environmental effects, and performance are welcome. In
addition, presentations dealing with the sensitivity of composition,
processing, microstructural parameters or mechanical properties (possibly
approached through literature curation, data mining, and machine learning) are
encouraged.

Additive Manufacturing (AM) involves unique processing conditions, producing
microstructure and material properties that differ from those produced by
conventional methods. More research is still needed to fully understand the
capabilities of AM and the correlation between process conditions, process
parameters, microstructure and other material properties.
Titanium-based alloys are attractive for industrial use thanks to excellent
properties in terms of specific strength, biocompatibility, and corrosion
resistance. Titanium alloys are also expensive and challenging to machine. Thus
it is not surprising that titanium attracts a strong interest within the AM
community. The purpose of this symposium is to discuss AM processes and AM
materials having titanium as the main constituent, with focus on the
correlation between processing conditions and microstructure/material
performance, in a broad perspective. We welcome contributions on all types of
titanium-based materials: Unalloyed, alloys, intermetallics, composites, etc.
We also welcome contributions on new innovative titanium alloy compositions
tailored for additive manufacturing.

High entropy alloys (HEAs) have been defined as alloys that have larger than
1.5R of configuration entropy (where R=8.314J/(Kxmol) is the gas constant).
These alloys possess a "high-entropy effect," "sluggish diffusion effect," and
"severe lattice distortion effect." HEAs tend to exhibit attractive mechanical
properties at elevated temperatures and good corrosion resistance.
Titanium-based HEAs alloys are being investigated for potential biomedical and
heat-resistant applications. Unfortunately, symposia focusing on high entropy
titanium alloys are lacking. This symposium is intended to address this need
and topics of interest include (but are not limited to):
• High entropy titanium alloys, including alpha-beta alloys, metastable beta
alloys, and stable beta alloys
• Advanced processing of high entropy titanium alloys
• Phase transformation and microstructural evolution in high entropy titanium
alloys
• Mechanical behavior and performance of high entropy titanium alloys
• ICME, materials informatics, and machine learning for the discovery of
composition-processing-microstructure-property relationships of high entropy
titanium alloys

As the principles outlined in the Materials Genome Initiative continue to take
root in our field, computational tools applied to integration (establishing
connections along the process-structure-property-performance continuum) and
analysis (gaining insight about a specific element of the ICME framework though
simulations or machine learning-based frameworks) in materials engineering
proliferate. Although broadly beneficial, this has led to some redundancy of
effort among researchers unaware that many of the practical tools they need may
already exist. Practical computational tools ready to address day-to-day
integration and analysis challenges are valuable to industry practitioners and
an associated symposium could draw additional industry participants to the TMS
Annual Meeting.
In light of this, the objectives of this symposium are to (1) serve as a forum
to present new computational tools that can be readily applied to materials
integration and analysis challenges in industry, academia, and government, (2)
stimulate sharing the code and data associated with each presentation through
an online repository (e.g. GitHub, Materials Data Facility, etc.) so that the
audience and materials community can access the tools, and (3) provide a
persistent link between the presentation/ProgramMaster listing, code
repository, and optional IMMI publication.
Abstracts in either of the following categories are sought:
• Presentation of a computational tool developed and applied to integration or
analysis of materials models, experiments, and data. Presentations in this
category emphasize discussion of the underlying theory and implementation of
the computational tool, limits and examples of its application, and instruction
for use by the audience and broader materials community.
• Presentation of a new research result that employed a novel computational
tool for integration or analysis of materials models, experiments, and data.
Presentations in this category emphasize discussion of the research result
along with details of the computational tool sufficient to give general
instruction for use by the audience and the broader materials community.
In all cases, presenters will be required to upload the code and data
associated with their presentation to a publicly accessible repository with
defined expectations on data and code discoverability, ability to be cited, and
longevity (to be identified by the symposium organizers and TMS). Presenters
are also encouraged to submit a paper aligned with their presentation to IMMI
(https://link.springer.com/journal/40192). Presenters are encouraged to
consider the use of non-traditional formats in their presentations, including
(for example) combining traditional slides with demonstrations or working code
or notebooks as necessary.
Additive Manufacturing (AM) opens new opportunities not attainable with
conventional manufacturing technologies. AM involves unique processing cycles,
producing microstructure and material properties that differ from those
produced by conventional methods.
AM continues to attract attention of professional communities including
research, design, and process engineers. However, more research is still needed
to fully understand the capabilities of these processes and the correlation
between process conditions, process parameters, microstructure and other
material properties.
This symposium is a derivative of the AM symposium on microstructure and
material properties held at MS&T in previous years. Titanium-based alloys are
attractive for industrial use thanks to excellent properties in terms of
specific strength, biocompatibility, and corrosion resistance. Titanium alloys
are also expensive and challenging to machine. Thus it is not surprising that
titanium attracts a strong interest within the AM community. The purpose of
this symposium is to discuss AM processes and AM materials having titanium as
the main constituent, with focus on the correlation between processing
conditions and microstructure/material performance, in a broad perspective. We
welcome contributions on all types of titanium-based materials: Unalloyed,
alloys, intermetallics, composites, etc. We also welcome contributions on new
innovative alloy compositions tailored for additive manufacturing.
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.
The ability to design and repeatedly produce complex, highly durable components
for demanding aerospace applications is generally taken for granted these days,
but this was not always the case. Edisonian techniques and institutional
knowledge were the prevailing methods to choose alloys and develop processing
routes with a primary focus of form over function. Little attention was paid to
material microstructure and its evolution over the course of processing, and
even fewer attempts were made to model it. This all changed when a small group
of scientists and engineers came together at Battelle Memorial Institute in the
late 1970’s and worked on a wide range of metals processing techniques. Their
early success, leveraging the momentum building in the steel industry during
World War 2, stemmed from their combined expertise in mechanics, metallurgy,
processing science, and computational methods. Their work was constantly
advancing the state of the art and often far before the rest of the world was
ready for it. For example, their team was the primary contractor for the very
first Air Force Materials Lab Processing Science Program. During this program,
the team developed (what we call now) a foundational engineering problem using
integrated computational materials science and engineering (ICME, or "ICMSE" in
some places) to optimize the process for creating a
dual-microstructure/dual-property Ti-6Al-2Sn-4Zr-2Mo disk – and they did this
~25 years before the widespread adoption of ICME in our community.
They were masters of understanding processes and developing practical
simulations of them. They devised elegant and convincing validation experiments
and paid careful attention to boundary conditions, process parameters, and
material behavior under processing conditions. Their work at Battelle and that
which followed when they each went their separate ways has touched every facet
of metals processing including: solid, liquid, and vapor phase processes, power
and wrought metallurgy, conventional and solid state joining processes,
high-speed machining processes, and additive manufacturing (a decade before the
current explosion of effort). Their work touched a vast array of
technologically important materials including titanium and its alloys,
nickel-base and cobalt-base superalloys, aluminum alloys, various
intermetallics, and high entropy alloys, among others. Within these alloy
systems, the honorees have contributed well over 1,000 papers to the body of
literature on analytical and numerical modeling of microstructure and texture
evolution and collectively advised over 200 graduate students! Their work led
to the formation of a small business focused on simulating virtually every
aspect of the metals processing value stream in the early 1990’s. This company
continues to thrive today and is an integral part of the aerospace metals
supply chain that produces flight-critical rotating components. The
contributions of Taylan Altan, Wei Tsu Wu, Soo-Ik Oh, and Lee Semiatin to the
field of processing science are so vast and impactful that it is the Structural
Materials Division’s great pleasure to honor their lifetime of achievements at
TMS 2020.
Paying homage to the honorees lifelong commitment to developing and validating
process models, this symposium will remain alloy-agnostic and instead keep
central themes of processing, process simulation, and modeling the evolution of
microstructure/texture/defects during processing. Hence, this symposium seeks
papers on any metallic material system in the following areas: (1) wrought
processing, (2) powder production, (3) powder processing, (4) melting and
casting, (5) solid-state joining operations, (6) additive manufacturing, (7)
machining operations, and (8) application of numerical methods in processing.
Preference will be given to papers that combine experiment with modeling for
greater insight into material behavior and also those that span more than one
of the above topic areas. Invited speakers from academia and government labs
will highlight the honoree’s technical breadth and depth while those from
industry will highlight the impact of their work in a production environment.
