Effect of the initial microstructure on the residual stress in the 20Cr<sub>2</sub>Ni<sub>4</sub> gear steel subjected to laser shock peening and shot peening

Effect of the initial microstructure on the residual stress in the 20Cr<sub>2</sub>Ni<sub>4</sub> gear steel subjected to laser shock peening and shot peening

ObjectiveThe influence of the initial surface topography on the residual compressive stress distribution along the depth direction of targets under laser shock peening (LSP) and shot peening (SP) processes was investigated.MethodsA finite element model for the composite strengthening of 20Cr<sub&...
