Short description
Short description
The operational behavior of steel components is significantly influenced by their residual stress state. On the basis of forward rod extrusion of stainless steel, methods for the controlled generation of residual stresses are being investigated, their stability under typical operating conditions is being analyzed and their effects on the operating behavior are being identified in this research project. In the first phase, basic mechanisms of the generation of residual stresses were identified. In the current second phase, parameters for a robust adjustment of the residual stress state during forming were developed, whereby lubrication in particular was identified as relevant. Furthermore, the influence of thermal and mechanical loads on the stability of the residual stresses in the components is being investigated.
