Introduction
Today, reduction of weight of material is an actual subject in wide areas of automotive and mechanical engineering. Several possibilities are available, like better utilization of the material by higher hardness or optimizing the construction by finite elements. Two further possibilities are rolling of components and shot peening or the later developed stress peening. Because it is possible to induce compressive residual stresses in dedicated amounts, it is used very often at tensile pulsating load to get a better utilization of the material. The two possibilities have different advantages, which are on the one hand cheaper realization and so huge amount of induced residual stresses like vice versa.
