Experimental investigation of laser peening on Ti17 titanium alloy for rotor blade applications

•Laser peening on Ti17 titanium alloys is investigated.•Roughness and residual stress value were grown on laser energy and impact times.•Hardened layer depth increases significantly with laser peening impact times.•Laser peening is effectively in lower fatigue stress level.•Laser peening makes the m...
