英文摘要：

With low density, high specific strength, low elastic modulus, high melting temperature and favorable corrosion resistance and tissue compatibility, Ti and its alloys have been considered as a first choice for biomedical application. In this paper, the main characteristics and advantages of titanium alloys fabricated by powder metallurgy were briefly introduced. The recent research progresses and application of the P/M biomedical Ti-alloys were reviewed, especially in terms of powder preparation, forming, sintering and properties. The further development trend and application prospect of P/M Ti-alloys were analyzed in view of the existing problems of clinical application.
