| Abstract |
|
This paper presents recent developments on press and sintering of titanium from metal hydride powder. Titanium hydride offers a low cost solution compared with pure titanium powder. Different lubricants have been used for uniaxial compaction in an electric press. Dog bone specimens for tensile tests have been pressed, dehydrided and sintered. Sintering was performed in a muffle furnace at temperatures between 1100°C to 1400°C under argon. Sintered parts exhibit a linear shrinkage of about 13%. The yield strength (575 MPa), ultimate tensile strength (704 MPa), elongation to fracture (20%) and interstitial content measured by melt extraction meet the requirements for titanium grade 4. |
