抄録

In recent year, studies about creating titanium implants using a layered manufacturing process have been conducted. In this study, Ti-6Al-4V alloy was created using an electron beam and Ti-6Al-4V powder in the layered manufacturing process. The mechanical properties of the manufacturing material were analyzed. Ti-6Al-4V alloy created using the layered manufacturing process had the following properties: its microstructure was acicular with an alpha structure; it satisfied the strength and elongation requirements for wrought Ti-6Al-4V alloy for surgical implant applications; its fatigue limit was about 550 MPa, lower than wrought Ti-6Al-4V alloy.
