Abstract

The large pulsed electron beam (LPEB) is recently highlighted as a surface modification method of metallic alloys owing to various advantages such as high thermal gradient and fast processing speed compared to conventional surface treatments. Besides its effect on surface properties, the effect of LPEB irradiations of fatigue behavior of metallic alloys is yet to be explored. In this study, effects of the LPEB irradiation on fatigue behavior of Ti-6Al-4V titanium alloy were investigated. The mechanisms of changing fatigue characteristics were specified relating it with changes in physical properties such as hardness, surface roughness, phase transformation, and residual stress.
