Abstract Titanium and its alloys are widely used in aerospace, automobile and ship, petrochemical industry, biological medicine and other fields because of their low density, high strength, good corrosion resistance and good biocompatibility. The article mainly aims at the preparation technology of powder metallurgy of titanium and titanium alloys, current situation are introduced. Powder manufacturing and densification at home and abroad are introduced. It is pointed out that the key for the future development of powder metallurgy titanium alloys is the preparation of low clearance element fine titanium powder, large size green and high performance sintered preform.
