摘要：
The changes of surface topography, surface roughness, surface residual stress and compressive residual stress field caused by shot peening and their effects on fatigue properties of Ti-60 high temperature titanium alloy at 20 and 600 degrees C were investigated. The results show that the fatigue limit for 1 x 10(7) cycles is increased by similar to 39 and 15% by shot peening at 20 and 600 degrees C respectively.
