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.

2020 TMS Annual Meeting & Exhibition: Advanced High Strength Steels IV: Organized by Ana Luiza Araujo; Mary O'Brien; Tilmann Hickel; Amy Clarke; Kester Clarke; C. Tasan; MingXin Huang

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).

2018 TMS Annual Meeting & Exhibition: Advanced High-strength Steels: Organized by MingXin Huang; Tilmann Hickel; Amy Clarke; C. Tasan; Young-Kook Lee; Matthias Militzer

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 property combinations (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
