| Abstract: | This paper deals with test methods of impact.Fatigue of forging die under load, and the technological ways of improving impact fatigue behaviours of forging die after EDM. The results show that the impact fatigue life-time of the specimen will increase by means of high-temperature temper and shot-peening after EDM with the water-base working fluid. The data in the paper reasonably account for the results obtained before, and the technological ways to improve the fatigue behaviours of forging die are proposed. |
