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
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
(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
(10) Other properties of electrical steels, e.g. chemical, physical,
mechanical, electrical, 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
• Conventional mechanical tests (tensile, charpy, bending, etc.) and
microstructure analyses methods (SEM, EBSD, XRD)
• Advanced characterization techniques (HRTEM, APT, and in-situ
• 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
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
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
Contributed talks will be 5 minutes (3 slides max) in duration to introduce the
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
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).
Advanced high-strength steels (AHSS) are particularly important to the
automotive industry. The application of AHSS on automobiles is an effective way
to reduce the weight of vehicles and therefore the fuel consumption while
maintaining the passive safety. To address the current and future needs to
reduce even further the weight of vehicles in future car designs, new AHSS
grades are actively being researched in industry and academia. This symposium
focuses on the latest developments in high-strength low alloy (HSLA) steel,
dual-phase (DP) steel, transformation-induced plasticity (TRIP) steel, complex
phase (CP) steel, martensitic steel, twinning-induced plasticity (TWIP) steel,
quenched & partitioned (Q&P) steel, Mn-TRIP steel and press-hardened steel
(PHS). This symposium invites contributions on the understanding of
process-microstructure-property relationships of AHSS. Application of advanced
characterization techniques on AHSS with a particular focus on the nanoscale is
welcome. In addition, advanced modelling and simulation of AHSS related
phenomena, with a particular focus on ab initio methods, computational
thermodynamics, constitutive laws as well as integrated computational materials
engineering (ICME), will be discussed.
The symposium includes, but not limited to, the following topics:
(i) Alloy design and/or thermo-mechanical processing of AHSS towards improved
(ii) Micro-mechanisms of phase transformation, plasticity and damage in AHSS
(iii) Hydrogen and liquid metal embrittlements
(iv) Application of advanced characterization techniques on AHSS
(v) Advanced modelling and simulation of AHSS relevant phenomena
