**4. Conclusions**

In this study, Ti6Al4V powder, which was used as a metal matrix of biocomposites and EB powder with excellent bioactivity, was successfully manufactured using powder metallurgy and SPS. The Ti6Al4V-EB composite powders as a function of EB mass fraction (0.05, 0.5, and 5 wt.%) were ball-milled for 12 h, and the bulk composites were consolidated using SPS at 1000 ◦C. The microstructures with phase analysis and mechanical properties were analyzed using the sintered Ti6Al4V-EB composites.
