This paper introduced the principle and application of warm laser shock peening, aiming at the existing problems in engineering application, and summarized the research status and academic achievements of domestic and foreign. From residual stress failure and tissue instability under high-temperature and alternating load, the mechanism of residual stress release induced by laser shock peening was analyzed. The auxiliary heat source based on laser shock peening is analyzed (WLSP), which can promote dynamic strain aging and dynamic precipitation in the process of laser impact reinforcement (LSP), and the dispersion distribution reinforcement phase is precipitated around the dense dislocation, and the strengthening phase is further nailed and positioned. Fault forms air mass. The stability of high temperature tissue and creep resistance of the material are significantly improved. At last, the future development of warm laser shock peening was looked forward.
