Thermal Stability of Residual Stresses in Differently Deep Rolled Surface Layers of Steel SAE 1045

Abstract The stability of compressive residual stresses generated by deep rolling plays a decisive role on the fatigue behavior specimens and components, respectively. In this regard, at elevated temperature has proven to be very effective in stabilizing when analysis is conducted ambient temperature. However, since can affected not only plastic deformation but also thermal energy provided, it necessary analyze influence time relaxation To evaluate effect temperatures limits under as well combined thermo-mechanical loads, present work introduces discusses results investigations differently rolled material conditions steel SAE 1045.
