A laboratory evaluation of duplex annealed Ti--8Al-1Mo--1V sheet showed that 1850 deg F (5 min) and air cooled (AC) + 1100 deg F (8 hr) provided an optimum combination of room- and elevated-temperature tensile, sub-zero temperature notch tensile, and creep properties. Contamination was found to extend to a depth of 0.002 to 0.0025 in., which is entirely commensurate with finish grinding and/or pickling procedures being used. A more extended study of the effect of finish annealing temperature on the creepstability properties of Ti- -5A1--5Sn--5Zr and Ti--7Al-12Zr sheets resulted in the selection of 1650 deg F (1/ 2 hr) AC as the optimum final annealing cycle for both alloys. Preliminary evaluation of welded Ti--5A1--5Sn-5Zr and Ti-7Al-- 12Zr showed that good as- welded and welded-andannealed properties can be achieved. (auth)
