Abstract : In the present study a new phase fraction based transformation hardening and further a stress and temperature dependent transformation kinetics following the postulates in internal variable thermodynamics is presented. The generally formulated kinetics equation is applied to describe the progress of phase transformation in a Cr-Ni-Mo-Al-Ti maraging steel and represents a good tool to predict the continuous change of the slope of isovolume fractions.

Keywords : Transformation hardening Stress dependent kinetics Transformation induced plasticity Martensitic transformation Constitutive modeling
