| Abstract: |
| Residual stresses, deformed microstructures after shot peening and its exchanges in the temperature field and the relationship between fatigue and the factors mentioned above have been investigated. lt was shown that the elevated temperature fatigue strength can be improved by shot peening strenthening. |
