Abstract: A simulation of the heat treatment processes requires material data for the description of phase transformation. Those data refer not only to the transformation without external loads, since during the heat treatment transformation and thermally caused stresses develop, which affect the behaviour of the phase transformation. Interaction between phase transformation and external stress is the subject of these investigations. The investigations show the influence of constant tension and compression stresses on the transformation kinetics during the isothermal pearlitic and bainitic transformation and also the martensitic transformation of the bearing steel 100Cr6 (SAE 52100). This paper shows the transformation plasticity parameter K for different phases. Also, we introduce some models to describe the evolution of the transformation plasticity.
