喷丸对DD3单晶高温合金高周疲劳性能的影响

The Effect of ShotPeening on the HighCycle Fatigue Properties of Single Crystal Superalloy DD3

对两种取向的ＤＤ３单晶高温合金进行了高周疲劳性能试验。结果表明：［１１１］取向的疲劳极限在喷丸后降低。

This paper describes the high cycle fatigue properties of the two orientations of single crystal superalloy DD3The results showed that after shotpeening,the properties of orientation was lowered,and the properties of orientation was raised
