On the interaction between transformation induced plasticity and the austenitic stainless steel anisotropy (AISI 304) under shear loading path

It is well known that for the AISI 304 austenitic stainless steel some parameters such as temperature, strain rate, material anisotropy and loading path are the main factors which strongly affect the kinetic of transformation induced plasticity (TRIP) in this material. In literature, tensile and compression tests represent the commonly experimental tools studied on this material. Under such type of loading, dissymmetry plastic behavior was obtained due to the martensitic kinetic evolution. The aim of the present work is to highlight the role of the TRIP phenomenon on the initial material anisotropy of the AISI 304 material using appropriate experimental framework. The cross-coupled effect of the phase transformation on initial anisotropy is studied through special loading test (simple shear test (SST)) conducted at various temperatures.
