Investigations reveal the relationship between laser shock treatment modes and fatigue characteristics in titanium alloy VT6, suggesting important implications for material strength.
The influence of laser radiation power density during laser shock treatment of titanium alloy BT6 on the properties of the surface layer: geometry, microhardness, degree of riveting, residual stress level and microstructure is studied. Comparative fatigue characteristics of samples strengthened in different modes of laser shock treatment are presented. Fractographic analysis is carried out and the relationship between the modes of laser shock treatment and the depth of fatigue crack initiation is determined.
