ORTHORHOMBI CRYSTAL TITANIUM-NIOBIUM ALUMINIDE CONTAINING VANADIUM

摘要

PURPOSE: To produce a titanium-aluminum alloy improved in room temp. ductility and room temp. fracture toughness by incorporating specified ratios of Al, Nb and V into Ti. ;CONSTITUTION: A titanium-aluminum alloy contg., by at.% about 18 to 30% Al, about 18 to 34% Nb, about 0.25 to 7% V, and the balance substantial Ti is prepd. In this way, the titanium-aluminum alloy contg. a rhomic crystal shape in a ratio substantially occupied at least by 25% of the volume of the alloy microstructure can be obtd.;COPYRIGHT: (C)1993,JPO
