MECHANICAL AND THERMAL PROPERTIES OF HIGH-TEMPERATURE TITANIUM ALLOYS

Abstract

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.
