Abstract
A Ti--Al--V--Cr intermetallic alloy having an atomic percent composition of 5-35 Al, 10-15 (V+Cr), the balance being Ti. The alloy is partially of DO.sub.19 type and partially of B2 type and has high temperature strength and excellent room temperature ductility. The alloy is produced by arc melting the metallic components Ti, Al and at least one of V and Cr; followed by homogenizing the melted components; solidifying the melted components to form an alloy; hot working the solidified alloy by isothermal forming to form a beta-phase polycrystalline microstructure; transforming the metastable .beta.-phase into a two-phase microstructure; and equilibrating the two-phase microstructure by prolonged annealing.
