Abstract: In production engineering, current research focuses on the induction of targeted residual stress states in components in order to improve their properties rather than follow the usual path of minimizing residual stresses to prevent failure. In this contribution, a focus is laid on the investigation of the subsequent cooling process of hot bulk formed parts. Such cooling of a component leads to a microscopic phase transformation, which has to be considered in order to compute residual stresses inside the material. A numerical approach based on a phenomenological macroscopic material model is presented to depict the related stress evolution.
