Titanium alloy weighs approximately 50% less than steel or corrosion resistant alloy, which makes titanium alloy an excellent candidate material for high-strength fasteners in both aerospace and automotive industries. Powder Metallurgy (PM) approach is a viable and promising route for cost-effective fabrication of titanium components due to the usage of low-cost raw materials, high workability and near net shaping. Therefore, PM technology has potential for fabricating low-cost titanium fasteners. In the present study, PM titanium fastens were prepared through cold isostatic pressing (CIP), vacuum sintering and hot working. The mechanical properties were characterized, and the ways to improve the properties were discussed. The results show that the ultimate tensile strength, ductility and fatigue limit are 1205MPa, 12% and 420 MPa, respectively, which are good enough to be used as fasten materials.
