The purpose of this program was to obtain preliminary mechanical- and thermal-property design data on some of the newer titanium alloys. Three sheet alloys Ti-5A1-5Sn-5Zr, Ti-5A1-5Sn-5Zr-1Mo-1V, and Ti-6A1-2Sn-4Zr-2Mo and two bar alloys Ti-5A1-5Sn-5Zr and Ti-679 were studied. Results of the tests show that the new Ti-6A1-2Sn-4Zr-2Mo sheet alloy has well-balanced properties with short-time strength at all temperatures comparable to or higher than those of other alpha-beta alloys and higher long-time strength creep than other alpha- beta alloys to which it was compared. The Ti-679 bar alloy also exhibited generally high strength over the temperature range 70 to 1000 F at which properties were studied.
