ABSTRACT:
A method for making an .alpha.+.beta. titanium alloy comprising: preparing an .alpha.+.beta. titanium alloy, hot-working the titanium alloy in an .alpha.+.beta. phase region, heating and then heat treating the hot-worked titanium alloy to a temperature from the .beta.-transus minus 55.degree. C. to the .beta.-transus minus 10.degree. C., air cooling the heat treated titanium alloy, heating and then heat treating the air cooled titanium alloy to a temperature from the .beta.-transus minus 250.degree. C. to the .beta.-transus minus 120.degree. C., and air cooling the heat treated titanium alloy.
