Abstract
1369289 Heat-treating titanium alloys UNITED AIRCRAFT CORP 24 July 1972 [6 Oct 1971] 34555/72 Heading C7A Alpha-beta alloys are solution treated in the α/# region within 55 C. of the # transus to develop primary alpha-phase and then transferred directly to an isothermal treatment bath, particularly of a molten salt, at a temperature low in the α-# field and within 110 C. of the α transus, where they are held to develop a desired amount of secondary α. There then follows cooling and subsequent precipitation hardening. Preferably the first stage of treatment is carried out at 871 to 927 C., the isothermal transformation at 760 to 817 C., and final hardening at 510 to 593 C. In a particular embodiment a Ti-6% AL-2% Sn-4% Zr-6% Mo alloy is forged at 885 to 899C., solution treated at 921 C for 1 to 2 hours, isothermally transformed at 829 C. for 15 minutes and aged at 510 to 593 C. for at least 8 hours.
