Titanium alloy parts for aerospace seek to meet strong demand for low costs. Powder metallurgy is expected to be low-cost processing technology of titanium alloy. An innovative powder densification technology known as SPS has been developed in recent years. The SPS process is a synthesis and processing technique which makes it possible to at low sintering temperature and in a short sintering duration. This study focuses on the mechanical and fatigue properties of Ti-6Al-4V and TiB/Ti-6Al-4V composites (TMC) prepared by spark plasma sintering (SPS) in vacuum. The microstructure, mechanical properties and fretting fatigue strength of the sintered Ti-6Al-4V and TMC were investigated.
