Taking the process of producing MIM Ti-6Al-4V alloy by HDH powder as a reference, the processes of making P/M Ti-6Al-4V and MIM Ti-6Al-4V by using TiH2 have been discussed. When using HDH Ti powder making MIM Ti-6Al-4V the tensile strength is 819 MPa and elongation percentage is 7%. When using TiH2 powder making P/M Ti-6Al-4V the tensile strength is over 850 MPa. And when using TiH2 powder making MIM Ti-6Al-4V, processes of dehydrogenation and debinding are successfully reached.
