Abstract
A thermal mechanical processing sequence for application to alpha-two type titanium is discussed. A typical alloy composition is 14% aluminum, 23% niobium, 2% vanadium, and balance titanium. Tensile ductilities in excess of 10% and up to about 40% are provided in this material by a processing sequence which includes multiple working steps below the beta transus with intervening thermal anneals also at temperatures below the beta transus. Typical rolling start temperatures would be on the order 954° C. (1750° F.). Typical annealing temperatures range from 732° C. (1350° F.) to 954° C. (1750° F.).
