Influence of Laser Shock Peening on residual stress and fatique life of stainless steels
Original language description
This paper shows influence of Laser Shock Peening (LSP) on Residual stress (RS) and Fatigue life of stainless steels. LSP is an innovative surface treatment technique for strengthening metallic materials. The principle of LSP is based on conversion of laser energy into a shock wave that results in material plastic deformation and redistribution of RS. The aim of the RS redistribution is to move the compressive RS to maximally stressed area in component. Suitable RS redistribution in component, can lead to increase of component fatigue life. The paper is focused on the RS change and fatigue life after LSP treatment. The tested material was austenitic stainless steel which is used in nuclear industry. The depth profile of RS was measured by X-ray diffraction (XRD) and fatigue life was examined through the three-point bend fatigue test.
