2023 TMS Annual Meeting & Exhibition: Electrical Steels: Organized by Youliang He; Kester Clarke; Jun Cui

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 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.

MS&T22: Materials Science & Technology: Resisting Degradation from the Environment: A Symposium Honoring Carolyn M. Hansson’s Research and Pioneering Experiences as a Woman in STEM: Organized by Jenifer Locke; Brendy Rincon Troconis; Ashley Paz y Puente; George Gray; Suveen Mathaudhu; David Shifler

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.

2022 TMS Annual Meeting & Exhibition: High Performance Steels: Organized by Ana Luiza Araujo; C. Tasan; Jonah Kleem-Toole; Louis Hector; Tilmann Hickel; Benjamin Adam

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.

2021 TMS Annual Meeting & Exhibition: Advanced High Strength Steels V: Organized by Ana Luiza Araujo; Louis Hector; Igor Vieira; Lijia Zhao; Krista Limmer; Jonah Klemm-Toole; S�bastien Allain; MingXin Huang

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.
