The process development for 3 advanced weldable Tibase sheet alloys possessing improved elevated-temperature properties, Ti--8Al--1Mo--1V, Ti--5Al -- 5Sn--5Zr, and Ti--7Al--12Zr is summarized. The more important properties of each composition are discussed. Optimum procedures and conditions were established by processing several sheets from one ingot of each composition and evaluating the effects of various rolling and annealing temperatures on mechanical properties. A comprehensive evaluation of the properties of each composition showed that Ti-- 8Al--1Mo--1V is a higher strength alloy (130-Ksi minimum yield strength) with higher elastic modulus and lower ductility than either Ti--5Al--5Sn--5Zr (115-Ksi typical yield strength) or Ti--7Al--12Zr (125-Ksi typical yield strength) at temperatures through 800 deg F, but only minor differences in strength exist at 1000 deg F between the two higher strength materials, Ti--8Al--1Mo--1V and Ti-7Al- -12Zr. Sub-zero temperature (to --320 deg F) notch properties of Ti--5Al-5Sn-- 5Zr are superior to those of Ti--8Al-1Mo--1V and Ti--7Al--12Zr, although the latter two are not considered to be especially notch sensitive.
