Scope The need to improve fuel economy through reductions in vehicle weight has created a global demand for advanced high strength steels. Recent advances in computational alloy design methods and microstructural development during processing have produced several new classes of steel alloys that demonstrate excellent combinations of properties. Many of these new alloys contain complicated metastable phases that are able to transform during deformation, (e.g., transformation-induced plasticity (TRIP) steels), and as such, often exhibit novel temperature and strain path-dependent behavior. Property data and constitutive relationships that accurately describe the mechanical behavior of alloys with complex microstructures are needed to improve the reliability of numerical formability models. The current inability to consistently predict the mechanical response of these alloys under the complex loading generated during sheet metal forming creates significant obstacles that impede the widespread incorporation of these steels.

The main objective of this symposium is to provide a high-level scientific forum that spotlights the numerous advances in the experimental and computational methods used for constitutive analyses and improves our knowledge of the mechanical and metallurgical responses of advanced high strength steels to complex sheet forming processes. This includes increasing our understanding of the relationships between complex microstructures and mechanical behavior, as well as the relative influences of strain path and temperature on formability and failure.

Abstracts are requested in the following general topic areas relating to advanced high strength steels: enhanced mechanical property measurement methods including advanced in-situ technique development; characterization of phase transformations and deformation mechanisms in multiphase microstructures during forming; theory and modeling related to the mechanical properties; deformation simulations, forming processes, friction and springback; multi-scale mechanical testing; integration of scientific knowledge with manufacturing practices; and development of accurate constitutive relationships.
