Abstract:  
Before the sixties, the shot peening was ordinarily used only for the machinery parts working at ambient temperature but at high temperature. Since the sixties it had been used to improve elevated fatigue behavior of different superalloys in our country. A lot of elevated parts and components of turbine engine rupture due to the elevated fatigue. Therefore, the research for the influence of shot peening on the elevated fatigue behavior of machinery parts and components has an important significance. The influence of shot peening on the elevated fatigue behavior of the specimens with different stress concentration factors has been investigated in the present article.
