Abstract
The powder layered manufacturing has attracted attention as a technique for producing implants in near net shape. In this study, the bending fatigue property of plane specimen of titanium alloy fabricated by means of electron beam melting method (EBM) is evaluated. The bending fatigue properties of the EBM materials subjected to fine particle peening (FPP) were also studied. The fatigue properties of EBM material was found lower than that of conventionally manufactured material because of defects introduced during manufacturing process worked as initiation sites of fracture. It was found that the surface modification process examined in this study, FPP is effective on improving the plane bending fatigue properties of EBM material. Therefore, it is believed that FPP is effective treatment.
