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°C were investigated. The results show that the fatigue limit for 1 × 10 7 cycles is increased by ∼39 and 15% by shot peening at 20 and 600°C respectively.
