This paper aims to find out the fabrication conditions of Ti-Ni shape memory alloy by metal injection molding and to examine the influence of the fabrication conditions on the tensile properties and shape memory characteristics of the alloy. Ti gas-atomized powder and carbonyl Ni powder mixed well with polyacetal binder and injection-molded into a mold for tensile test specimens. The injection-molded compacts were debound and then sintered at various temperatures for 7.2 ks and 42.3 ks. The density of the sintered compacts was greatly influenced by the sintering temperature. The tensile strength and elongation of the compact sintered at 1423 K for 7.2 ks were 1 10 MPa and 5%, respectively. The obtained alloy evidently showed shape memory effect.
