The mechanical coupling effect of laser shock and shot peening in Ti–6Al–4V dovetail joint: Residual stress, microstructure and fretting fatigue behavior

The mechanical coupling effect of laser shock and shot peening in Ti–6Al–4V dovetail joint: Residual stress, microstructure and fretting fatigue behavior

This research systematically investigates the strengthening effects of laser shock peening (LSP), shot peening (SP), and combined LSP + SP on the fretting fatigue behavior of Ti–6Al–4V dovetail joints under different load levels. Multi-scale characterization reveals that all treatments generate grad...
