Abstract:
With a new system shot peening and stress peening using an air blast machine at elevated temperatures is feasible. The effects of conventional shot peening, stress peening,
warm peening and stress peening at elevated temperatures on the characteristics of near surface layers, on the stability of residual stresses and half widths and on the
fatigue strength of a quenched and tempered AISI 4140 steel (German grade 42 CrMo 4) will be presented. The alternating bending strength is increased by stress peening as
well as by warm peening compared to conventional shot peening.
