The effect of laser shock peening, shot peening and their combination on the microstructure and fatigue properties of Ti-6Al-4V titanium alloy

[Display omitted] •The fatigue life can be significantly improved (up to 9.3 times) by (LSP+SP).•Gradient microstructure with dislocations and novel CRS distribution can be induced.•Fatigue crack initiation can be hindered by the high-density dislocation layer.•Fatigue crack growth rate can be retar...
