| Abstract: | The relationship between residual stress field,microstructure,density in the surface shot peening layer and the fatigue behavior for hot isostatically pressed(HIP) powder superalloy Rene'95 have been investigated. It has been shown that the high cycle and the low cycle fatigue strength can be obviously improved by shot peening. |

| Keywords: | powder metallurgy superalloy residual stress subgrain fatigue strength |
