| Abstract: | Powder metallurgy of the Ti-6Al-4V alloy using titanium hydride powder and Al-V alloy powder, in vacuum furnace where dehydrogenizing and sintering could be joined has been researched.The results show that sintering density 4.4 g/m~3, tensile strength 854.89 MPa and elongation 3.8%.Above mentioned,these properties are in step with abroad,and that the technique of Ti powder produced was simplified, as a result decreased the inclusion in the alloy and reduced energy cost. |
