Abstract
Aiming at the application problems of laser shock processing on the aero-engine high temperature components, thin blade, blade- mortises/tenon teeth and other complex parts (regions), we carried out a systematical research on surface nanocrystallization induced by laser shock processing. This article summarized many studies about the characterization, theory and thermal stability of surface nanocrystallization of metal materials in various aero-engines. Moreover, we proposed a new strengthening mechanism of laser shock processing which was based on surface nanocrystallization and compressive residual stresses. Thereby, the application temperature of laser-peened high temperature components could be improved, and the engineering applications of laser shock processing on thin-wall construction, mortises/tenon teeth and other special parts (regions) were introduced. The research on laser-induced surface nanocrystallization and compound strengthening mechanism, which broadens the study area and application field of laser shock processing.
