PROPERTIES OF NEW HIGH-TEMPERATURE TITANIUM ALLOYS

Abstract

The memorandum compares and summarizes the compositions, recommended heat treatments, and basic physical and mechanical properties for a group of 12 relatively new titanium alloys. Most of these were developed for service above 600F as bar and forging alloys and can be considered as alloys of the 'super' alpha class. These include the Ti-6Al-2Sn-4Zr-2Mo, Ti-5Al-5Sn-5Zr, and Ti-7Al- 12Zr compositions, which were developed in the United States, as well as the series of IMI-679, -680, -EX 684, and -EX 700 alloys and of Hylite 50, 51, 55, 60, and 65 alloys, all of which were developed in the United Kingdom. In addition, some preliminary data are presented for a silicon-modified version of the Ti-6Al-2Sn-4Zr-2Mo alloy.
