Abstract

Hot bulk forming processes offer great opportunity to adjust the component’s properties in preferred manner. The set degree of deformation during the forming step but especially the cooling step have substantial influence on properties such as life time, strength or wear resistance. Main focus lies on the evocation of “favorable” residual stress states in the material, which arise particularly due to phase transformation in consequence of cooling. Numerical simulations offer a time- and cost efficient possibility to investigate different cooling routes and their effect the resulting stress evolution in order to obtain a targeted final residual stress distribution.
