Abstract：High temperature alloys were important materials for key components of aircraft engines， and shot peening was a critical step in the manufacturing process of blade parts. Through the high-speed impact of the projectile on the surfaces of the workpieces，residual compressive stress might be introduced to the surfaces，thereby ofseting some working loads and improving the fatigue performance of the compo nents.Therefore，studying the shot peening processes of high-temperature alloys was of great significance for improving the service performance and reliability of key components in aircraft engines.This paper introduced the research status of high-temperature alloy shot peening processes in terms of simulation methods，surface integrity of high-temperature alloy shot peening，and fatigue performance of high-temperature alloy shot pening. Finally，the shortcomings of existing research and future research directions were analyzed.
