Abstract:Applications of high strength & toughness titanium alloys, high-temperature titanium alloys, lower-temperature titanium alloys, and casting titanium alloys in aerospacecrafts are introduced. The status and directions for development of titanium alloys are described. At the same time, advanced forming technologies about titanium alloys applied in aerospacecraft, such as powder metallurgy technique and superplastic forming/diffusion bonding technology ( SPF/DB), are illustrated. The actuality and development of powder metallurgy technique in America and Russia are introduced in particular, and this technique has already been applied in the development of various types of products in our country. Meanwhile, SPF/DB provides a new approach to overcome some shortages in titanium processing, e. g. , high cost and dif- ficult processing ability.
Keywords:titanium alloy  high strength  high toughness  powder metallurgy  superplastic forming
