The thesis reviews the history and current situation of the preparation of titanium and titanium alloy from titanium hydride powder, and compares the technical preparation of titanium and titanium alloy with the corre- sponding wrought alloy performance. It points out that the preparation of titanium and titanium alloy through powder metallurgy technique has simple process, low energy consumption, high yield, small equipment investment, and can re- duce costs as well as make the alloys meet the application requirements, thus is applicable to manufacture small quanti- ties of varieties and specifications of medical titanium and discusses the future developing trends. products. Finally, it analyzes the existing problems in this field,
