With the aid of the Finite Element Method (FEM) simulation it is possible to predict results of the time‐temperature dependent mechanical properties by analysis. This paper presents a connection of the micro‐mechanical changes of material properties with a macroscopic approach to calculate residual stresses, local volume fractions of structural constituents, as well as the distortion of heat‐treated or heat‐influenced parts. This takes into account the kinetics of phase transformation in a mathematical formulation. Further on, this study shows the comparison between the simulation and experimental results.
