Abstract:
The process development for 3 advanced weldable Ti-base sheet alloys possessing improved elevated mperature properties, Ti-8Al-1Mo-1V, Ti-5Al5Sn-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 effect 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 T TEMPERATURES THROUGH F, but only minor differences in strength exist at 100 F between the two higher strength materials, Ti8Al-1Mo-1V and Ti-7Al-12Zn. Sub-zero temperature to -320F notch properties of Ti-5Al-5Sn-5Zr are sup rior to those of Ti-8Al-1Mo-1V and Ti-7Al12Zr, although the latter two are not considered to be especially notch sensitive.
