The General Status of the Refractory Metal was Reviewed Including its Characteristics and Application. the New Technology Research of Directly Prepared Refractory Metal from Refractory Metal Oxide was Discussed. FFC, OS and SOM Methods were Mainly Introduced. at the same Time, their Advantages and Disadvantages and the Difference between each other were also Pointed out. the Development Trends and Application Prospect of the Refractory Metal in Future were Prospected.

The development history of biomedical titanium alloy was reviewed in this paper. Because of high recovery strain, low stiffness facilitating integration with bone structures and good market potential of porous biomedical material, the most common methods for fabricating porous biomedical material were introduced. The advantages and disadvantages of the methods were summarized from the aspects of process route, reaction mechanism and porosity. The main direction for further studies in this field was also suggested.
