| Abstract: | in this paper, fatigue testing specimens of a Ni - base superalloy and austenitic stainless steel were shock processed by solid laser spot around the zone of stress constration. The variation of fatigue life after Laser shock processing was described. The results showed that, the fatigue life of these two materials was extended distinctly, but the extension changed much with different loading coefficient. |
