Abstract

Titanium alloys have been used especially as aerospace, medical and dental materials because of their excellent attributes of high corrosion resistance and high specific strength. A Ti-10V-2Fe-3Al is one ofβ-titanium alloy and it shows super-elasticity. In this study, the fabrication of super-elastic Ti-10V-2Fe-3Al alloy compacts by metal injection molding which is one of near net shape forming of powders was investigated using mixed elemental and alloy powders. Under the optimized MIM process condition, nearly full density (97∼98 %) was obtained and the tensile properties of strength and elongation were 1000∼ 1050 MPa and around 5 %, respectively. Moreover, after solution treatment and aging, the compacts with alloy powder showed clearly super-elasticity.
