Effect of co-strengthening of laser impact/mechanical shot peening on fatigue performance of TC4 titanium alloy damaged by foreign objects

Effect of co-strengthening of laser impact/mechanical shot peening on fatigue performance of TC4 titanium alloy damaged by foreign objects

Aiming at the problem that the fatigue performance of aeroengine blade leading edge was seriously degraded after foreign object damage（FOD）, the surface of TC4 titanium alloy thin wall specimen was treated by laser shock/mechanical shot peening, and the residual stress gradient distribution on the s...
