A Crystal Plasticity FE Analysis Considering Mechanically Induced Martensitic Phase Transformation

抄録

One of the most challenging topic nowadays for the steel manufacturers is the investigation of the role of the retained austenitic grains inside a martensitic body. The phase transformation of the former, in fact, has been proved to alter the material properties in terms of toughness, ductility, resistance and also it has be indicated as one of the probable causes for the crack initiation. The work presented in this paper aims to study this phenomena by means of a thermodynamically based single crystal constitutive model, coupling the crystallographic slip together with the phase transformation.
