Electrical steels are an essential energy converting material widely used in
generators, transformers, electric motors, and other electromagnetic devices to
confine the magnetic flux and amplify the conversions between electricity and
other forms of energy. The efficiency of these devices is largely determined by
the magnetic properties of the electrical steel sheets, and has a huge impact
on the generation, transmission, and use of electrical energy. With the strides
towards the decarbonization of the global economy by promoting renewable
energies, electrical steels are increasingly gaining momentum in the steel
market, especially for the production of electric vehicles in the
transportation sector, which is projected to grow significantly in the coming
years.
Microstructure and texture control to optimize the magnetic properties is still
the focus of electrical steel research. How to economically manufacture high
silicon electrical steel sheets using traditional technical routes is another
area to be explored. There are also new theories, processing technologies and
characterization methods proposed to advance electrical steel development and
manufacturing. This symposium provides a venue for researchers, engineers,
experts and enterprises from the world to share experiences, exchange ideas and
establish collaborations in this field.
The symposium includes but not limited to the following topics:
(1) Relationships among processing, microstructure/texture, and magnetic
properties of electrical steels.
(2) Alloy development for high silicon electrical steels with improved
formability.
(3) Casting and thermomechanical processing technologies to enable economical
production of high silicon electrical steels.
(4) Theories regarding the evolution of texture and microstructure during all
the electrical steel manufacturing stages.
(5) Novel characterization methods and tools to evaluate the microstructure,
texture and magnetic properties of electrical steels.
(6) Alternative manufacturing methods to produce electrical steel sheets.
(7) Coating and bonding of electrical steel laminates.
(8) The manufacturing and assembling of electrical steel cores.
(9) Effect of manufacturing processes on the energy losses of electrical steel
laminates.
(10) Other properties of electrical steels, e.g., chemical, physical,
mechanical, electrical, etc.
Steels have been and continue to be of fundamental importance for virtually all
aspects of industry and manufacturing in our modern society. This technological
importance motivates collaborative and multidisciplinary research between
industry, academia, and national laboratories to continuously grow the
fundamental understanding of steel behavior. While developing steels with
better properties and performance to meet increasing engineering requirements,
advancing sustainability of steel production, manufacturing and applications
needs to remain a priority.
The High-Performance Steels Symposium focuses on novel developments in steel
design and new insights into processing-microstructure-property relationships.
Improved understanding of these relationships calls for the following
approaches, including, but not limited to:
• Conventional static and dynamic mechanical tests (tensile, compression,
hardness, Charpy, bending, etc.) as well as failure testing (fracture, fatigue)
• Advanced characterization techniques (HRTEM, APT, and ex/in-situ
SEM/TEM/Synchrotron/neutron diffraction)
• Computational modeling efforts including physics-based or advanced
data-science approaches such as ab-initio modeling, computational
thermodynamics, discrete dislocation dynamics, crystal plasticity and Machine
Learning (ML) methods, in the spirit of integrated computational materials
engineering (ICME)
• Design of novel steel microstructures through computational or
high-throughput experimental approaches, and their validation;
This symposium welcomes contributions in all of these directions and especially
those that provide combinatorial approaches, providing a forum to discuss the
future of high-performance and sustainable steel design.
Limits on damage tolerance of metals in extreme environments are grand
technical challenges of today's industry. The sophisticated design of steels
for applications in extreme environments is often demanding due to complex,
dynamic, and multi-scale damage processes amplified by environmental effects.
This symposium is dedicated to discussing advancements in structural steels
exposed to a range of extreme environments and their failure analysis. These
include, but are not limited to, hydrogen embrittlement, CO2 degradation,
cryogenic temperatures, thermal cycling, irradiation, stress corrosion
cracking, and creep failure at elevated temperatures, as well as the
synergistic effects of these environments. The discussion will also address
diverse load-bearing scenarios such as forming, fatigue, and high-rate
conditions.
Austenite Formation and Decomposition V (AF&D V) is the 5th international
meeting on the decomposition of austenite following seminal meetings in 1962,
1984, 2003, and 2011. The decomposition of austenite is one of the most
important solid-state phase transformations in structural metals since it
dramatically influences the relationship between the microstructure,
properties, and performance of steels. Topics of interest include experimental,
theoretical and computational aspects of thermodynamics and kinetics of
austenite and phase stability, advanced experimental characterization,
austenite decomposition to bainite, martensite, etc., rapid thermal processes,
thermomechanical processing, alloying element effects, multiphase
microstructures, and property evolution. A special topic of focus for AF&D V is
ultra-fast austenite formation.
The phenomenon of solidification segregation can have a strong influence on the
quality of products and together with segregation during solid state
processing, e.g. at grain boundaries, can affect the final properties of
steels. Segregation is still extensively studied and several models, analytical
and numerical, have been developed to understand it while processes have been
improved to minimize it. On the contrary, fewer works have addressed the
potential use of segregation to develop new microstructures through the control
of chemistry, processing and phase transformations. In addition, the
correlation between specific types of segregation and properties has not been
totally elucidated.
The themes of the symposium include but are not limited to :
• Advanced and novel characterization techniques for micro-, meso- and
macrosegregation
• Influence of segregation on phase formation and final properties
• Modeling of segregation
• State-of-the-art techniques to modify segregation during processing
• New concepts based on segregation-induced transformations
As the most widely used and cost-effective structural alloys, steels play a
crucial role in advancing sustainability. Some of the most recent efforts for a
decarbonized future include the modification of steel production processes and
the adaptation of steel applications to reduce carbon footprint.
This symposium focuses on experimental or computational efforts to decarbonize
steel - via modification of steel production, design or applications - for
higher energy efficiencies and lower emissions, including (but not limited to):
- Designing robust alloys or processing routes to minimize production energy
and emissions and to improve scrap recyclability
- Designing high performance steels or low-density steels for low weight
applications, e.g. automotive applications
- Designing microstructures in optimized chemical compositions for extreme
environments, e.g. extreme temperatures and/or pressures, hydrogen
environments, etc.
- Steel alloy and processing developments for renewable energy applications

The profound technological importance of steels, and the everlasting challenges
to make them more superior, but also more sustainable, motivate
multidisciplinary research across academia, national laboratories, and industry
to continuously improve the fundamental understanding of steels and their
behavior. The High-performance Steels Symposium focuses on new insights in
steel design and processing-microstructure-property relationships. Providing an
improved understanding of these relationships requires the use of various
experimental and computational methodologies, including:
• Novel mechanical testing approaches (e.g., micro-mechanical tests, in-situ
tests, etc.) and microstructure characterization techniques (e.g. Synchrotron
diffraction, neutron diffraction, SEM-EBSD, SEM-ECCI, HRTEM, APT, etc.), as
well as new applications of conventional testing and characterization methods.
• Physics-based modeling of microstructure development and steel behavior
(e.g., ab initio methods, computational thermodynamics, crystal plasticity,
discrete dislocation dynamics, etc.) in the spirit of integrated computational
materials engineering (ICME).
• Computational or data-driven approaches to design and understand novel steel
microstructures
This symposium welcomes contributions in all of these directions, especially in
integrated approaches.
Martensite is a key phase in steels for diverse industrial applications,
including automotive, cryogenics, pressure vessels, and fuel systems. Yet
despite the large body of research on the subject, a gap persists in
understanding the relationships between the competing transformation phenomena
that occur during processing (auto-tempering, low temperature tempering,
transition carbides, twinning, etc.), the hierarchical microstructures that are
produced, and properties, including damage evolution in service.
The advent of advanced characterization techniques in recent years, in concert
with modelling approaches, have provided fresh views on the austenite to
martensite transformation, on martensite structure and chemical variations, and
on its evolution during processing. The knowledge acquired has given new
insights into the development of novel microstructure-property relationships.
It is thus timely to provide a status on these investigations in a dedicated
symposium with the aim of narrowing the gap in our understanding of
microstructural evolution and its impact on properties. This Symposium will
focus mainly on recent developments in the study of martensite in steels.
Abstracts are of interest on (but not limited to) the following topics:
• Observations of new phenomena and microstructural evolution during quenching
and tempering, service, and/or extreme environments
• Advanced characterization (development of new techniques and methods) of
microstructure and/or properties, as applied to martensite in steels
• Recent advances in multi-scale modeling of microstructure development during
processing, service, or exposure to external stimuli
• Microstructure-inclusive modeling of properties and performance
• High-throughput, combinatorial, or machine learning-guided alloy design and
development
This symposium focuses the history of materials science and engineering,
particularly in the 20th century when the field evolved out of chemistry,
physics, and engineering advances (recounted for example in R.W. Cahn: The
Coming of Materials Science, Pergamon, 2001). The story of just how this
paradigmatic shift in thinking and approach took place as MSE coalesced into a
recognizable discipline is of special interest. Also of interest are the more
specific tales of the discoveries and evolution of materials structure,
properties, processing, performance – and their later working out to deeper
insight and technological application. Experiment, modeling, and theory are all
of interest, as are all material classes. Of similar relevance is the
development of the institutions of materials science such as journals,
professional societies, academic departments, and stakeholders in government,
industry, and civil society. Those who participated in or who have some
connection with these events are especially encouraged to present.
Steels are the most widely used and cost-effective structural alloy in modern
society, and they will therefore have an important role to play as we move
towards more energy efficient and decarbonized technologies. From alloy design,
through production, to application, significant steel research is being
conducted to enable a sustainable future. Engineered microstructures in various
novel steel concepts normally comprise of two or more phases, often divided to
nanometer level with various functionalities.
This symposium focuses on efforts to design, produce, and apply steels for
higher energy efficiencies and lower emissions such as, but not limited to:
* Designing new steel compositions or processing technologies that can allow
production with less energy and lower emissions
* Steel alloy and processing developments that enable more extreme
temperatures and stresses in service
* Steels for extreme environments such as high-pressure hydrogen or liquid
hydrogen at very low temperatures or in contact with hydrogen carriers
* Low density steels for light weighting applications
* Steels for electric cars, for renewables, CO2 storage/transmission, etc.
* Advanced high strength steels for structural and wear-resistant applications
(automotive, shipbuilding, construction, rail transport, infrastructure,
aerospace, earth-moving equipment, mining, etc.)

Steels are one of the most pervasive structural alloy classes in modern
society. The profound technological importance of steels motivates
collaborative and multidisciplinary research between industry, academia, and
national laboratories to continuously improve the fundamental understanding of
steel behavior. While developing steels with better properties, we are also
challenged to make these new high performance steels more sustainable.
The High-performance Steels Symposium focuses on novel developments in steel
design and new insights into processing-microstructure-property relationships.
Improved understanding of these relationship calls for approaches that
incorporate:
• Conventional mechanical tests (tensile, charpy, bending, etc.) and
microstructure analyses methods (SEM, EBSD, XRD)
• Advanced characterization techniques (HRTEM, APT, and in-situ
SEM/TEM/Synchrotron/neutron diffraction)
• Physics-based or data-driven modeling of steel microstructures/properties
(e.g., ab initio methods, computational thermodynamics, discrete dislocation
dynamics, crystal plasticity) in the spirit of integrated computational
materials engineering (ICME).
• Computational design of novel steel microstructures and their experimental
validation
This symposium welcomes contributions in all of these directions, and
especially those that integrate these different techniques and approaches to
create a venue to discuss the future of high performance and sustainable steel
design.
Carolyn M Hansson is a Professor at the University of Waterloo in the
department of Mechanical and Mechatronics Engineering and cross-appointed to
the department of Civil and Environmental Engineering. In 2021, she will be
celebrating her 80th birthday. The technical scope of this symposium are topics
that intersect with one or more of her areas of expertise. While her focus has
been primarily with concrete and steels, for the purposes of this symposium we
will include all materials for greater inclusivity.
The topics of interest include corrosion, erosion, and wear of materials;
durability of construction materials; corrosion and electrochemical techniques;
techniques for measuring the amount of degradation; rust-resistant reinforcing
materials; sustainable materials; cement and concrete; and materials to
maintain the integrity of structures.
Carolyn Hansson was the first female student to attend the Royal School of
Mines at Imperial College, London, and the first woman to graduate with a PhD
in metallurgy from the same. She is Fellow of the Canadian Academy of
Engineering, Fellow of the Royal Society of Canada, Fellow of the American
Concrete Institute, Fellow of the Minerals, Metals and Materials Society (US),
and Fellow of the Institute of Materials, Minerals and Mining (UK). Professor
Hansson is the Associate Editor for Cement and Concrete Research and a member
of the Executive Committee of the Board of Governors of Acta Materialia.
A key feature of this symposium will be a 45 minute Fireside Chat with Carolyn
Hansson. There will be two people asking questions (one of which is a budding
metallurgist and corrosion expert). The key aspect to this part will be to hear
Carolyn's story. Specifically, what her career path was like, what advice she
has for young people (particularly those that are underrepresented) in moving
forward in a research and academic career, and what she is excited about in the
future research in her field.
After the Fireside chat, short talks that align with poster presentations will
occur.
Contributed talks will be 5 minutes (3 slides max) in duration to introduce the
author’s poster.
Invited talks will be 10 minutes (6 slides max) to discuss the impact of Dr.
Hansson and/or the impact of her research on your career and may include an
introduction to your poster (poster presentation along with the invited talks
are encouraged for this symposium).
The goal of the above is to avoid the typical symposium style and encourage a
deeper level of interaction and networking.
Immediately following the 5 and 10 minute introductory talks, all authors will
move to their poster and all in attendance will mingle to discuss in detail the
work highlighted in the short talks. The Poster Session will be held in the
symposium room immediately following the Fireside Chat and Invited/Contributed
Talks. The Poster Session will be an interactive/networking component.
Steels are critical for effectively all industries that form the core of human
civilization. This key role motivates collaborative research efforts amongst
industry, academia and national laboratories to continously improve the
fundamental understanding of steel behavior, addressing at the same time
current challenges to make steel production and applications more sustainable.
The High-performance Steels Symposium therefore focuses on novel developments
in steel design, and on new insights regarding
processing-microstructure-property relationships in steels. Improved
understanding of these relationship calls for multi-probe approaches that
incorporate (i) conventional mechanical tests (tensile, charpy, bending, etc.)
and microstructure analyses methods (SEM, EBSD, XRD); (ii) advanced
characterization techniques (e.g. HRTEM, APT, and in-situ
SEM/TEM/Synchrotron/neutron diffraction); and (iii) advanced modelling and
computational efforts (e.g. ab initio methods, computational thermodynamics,
discrete dislocation dynamics, crystal plasticity), in the spirit of integrated
computational materials engineering (ICME). This symposium welcomes
contributions in all of these directions, and especially those that integrate
these diffrent techniques and approaches, to create a venue to discuss the
future of steel design.
High Strength Steels (HSS) and Advanced High Strength Steels (AHSS) have been
widely used in commercial vehicles for a few decades. In recent years, the
demand for vehicle light weighting has pushed the development of new steel
grades (Gen3 AHSS) with a combination of high strength and high elongation that
are possible by careful alloying and processing design, often taking advantage
of retained austenite. Gen3 steels are becoming commercially available as more
steel producers offer high-strength and high-elongation products in their
portfolios. This symposium focuses on the latest developments of the more
traditional grades of HSS and AHSS as well as Gen3 steels, including but not
limited to: high strength low alloy (HSLA), dual-phase (DP),
transformation-induced plasticity (TRIP), complex phase (CP), martensitic,
quenched & partitioned (Q&P), medium manganese, TRIP-assisted bainitic ferrite
(TBF), press-hardened steel (PHS), twinning-induced plasticity (TWIP) and low
density steels. Submissions are encouraged to demonstrate in-situ techniques,
constitutive models, simulations, computational thermodynamics and kinetics,
integrated computational materials engineering (ICME), or other advanced
techniques that provide increased depth of understanding of these alloys. The
advances in the fundamental understanding of these alloys from this symposium
facilitate the acceptance and implementation of AHSS and Gen3 steels in
commercial vehicles.
Advanced high-strength steels (AHSS) are particularly important to the
automotive industry due to recent demand of light weighting for fuel
efficiency, while maintaining or improving passenger safety. Collaborative
research efforts amongst industry, academia and national laboratories have been
essential to develop and further understand the behavior of these AHSS alloys.
This symposium focuses on the latest developments in high-strength low alloy
(HSLA), dual-phase (DP), transformation-induced plasticity (TRIP), complex
phase (CP), martensitic, twinning-induced plasticity (TWIP), quenched &
partitioned (Q&P), medium manganese, TRIP-assisted bainitic ferrite (TBF),
press-hardened steel (PHS) and low density steels. This symposium invites
contributions on the understanding of processing-microstructure-property
relationships of AHSS. Application of advanced characterization techniques to
AHSS, with a particular focus on the nanoscale, is welcome. Furthermore, this
symposium encourages advanced modelling and simulation of AHSS to further our
understanding the performance of these materials via ab initio methods,
computational thermodynamics, and constitutive laws, for example, as well as
integrated computational materials engineering (ICME).
