Abstract

The effect of laser shock peening (LSP) on the residual stress and fatigue properties of 8Cr4Mo4V steel was studied by numerical simulation and experimental verification in terms of the residual stress evolution, microstructure observation, hardness and rotating bending fatigue performance tests. The results show that LSP causes a large compressive residual stress on the surface of 8Cr4Mo4V steel, which was acquired to be -607 MPa and -584 MPa by finite element method and the experimental measurement. During the process of LSP, the plasma shock wave may shatter carbides on the surface of the steel into smaller pieces, while induce the secondary precipitation of subsurface carbides and the severe plastic deformation of the substrate near the surface, thus increasing the surface hardness of the 8Cr4Mo4V steel. The increase of residual stress and surface hardness and the precipitation of secondary carbides on the subsurface may effectively inhibit the initiation of fatigue cracks and slow down the crack propagation rate. Therefore, the crack source is transferred from the surface layer to the subsurface layer. The fatigue strength of 8Cr4Mo4V steel after LSP is increased by about 45.95% and the rotating bending fatigue performance is significantly improved.
