TRansformation Induced Plasticity (TRIP) phenomenon results from the competition between two basic mechanisms, namely the orientation and accommodation. An accurate description of such a behavior is closely related to a good evaluation of the contribution of each mechanism in the overall response of the material. The main objective of this work is to provide an analysis of the different mechanisms at the microscale governing the TRIP phenomenon. The interaction between these mechanisms is experimentally displayed through nonproportional loading paths corresponding to the “creep” test. A micromechanical model is presented and tested under such conditions.
