Abstract
The problem of stress dependence on phase transformation has been reported in many papers. But from the view of continuum mechanics, only a few cases were analyzed and experimentally verified. In order to formulate the elastic plastic constitutive equation with the stress dependent effect on phase transformation, we carried out beinaitic transformation experiment of SCM440 under constant biaxial loading (tensile and torsional). Transformation induced plasticity (TRIP) strain components were measureed and compared with the theoretucal result.
