Abstract
Cast and forged titanium alloys suited for use at temperatures over 600.degree. C. are based on TiAl gamma phase structure. Useful alloys have about 1.5% or greater tensile ductility at temperatures of 260.degree. C. and below, thereby making them fabricable and suited for engineering applications. Disclosed are alloys having weight percent compositions of 31-36 aluminum, 0-4 vanadium, balance titanium (in atomic percent, about: 45-50Al, 0-3V, bal Ti). The inclusion of about 0.1 weight percent carbon improves creep rupture strength. To obtain high tensile strength, the alloys are forged at about 1025.degree. C. and aged at about 900.degree. C.; to obtain higher creep rupture strength and tensile ductility, a solution anneal at about 1150.degree. C. is interposed before aging.
