Abstract

This chapter presents the effects of the multiple LSP impacts on the residual stresses in the depth direction, focusing especially on the change of micro-structure in different layers in the treated sample by multiple LSP impacts, and clearly reveals the underlying refinement mechanism of plastic deformation after multiple LSP impacts on LY2 Al alloy.
