Abstract
Intergrated concepts for computational modelling and experiencing under the combined viewpoint of thermomechanics and material science will provide for new alloy design capabilities to exploit mechanical properties in terms of strength, ductility, toughness or enhanced energy absorption capability. Recently, a new type of high strength dual-phase steels associated with transformation-induced plasticity (TRIP) due to a strain-induced martensitic transformation (SIMT) has been developed [1], [2]. These low-alloy TRIP-steels show a good combination of total elongation and tensile strength at room temperature. The enhanced deformation capability comes from the mechanical properties of the martensitic transformation itself. It is attributed to the TRIP-phenomenon associated with the SIMT of the retained metastable austenitic phase under the effect of mechanical loading at constant temperature. The overall hardening is increased due to the mechanical properties of the emerging martensitic phase.
