On Ti-15-3 (a shortened designation for Ti-15V-3Cr-3Sn-3Al) and other two alloys which contain less V and Cr and more Al compared with Ti-15-3, the effects of alloy elements Al, V and Cr on beta transus temperature, aging behavior and mechanical properties were examined.
This variation in composition causes a little increase in beta transus temperature and nose temperature. At fully aged condition, it produces a little increase in hardness and great increase in alpha phase volume fraction. Among the effects, it is notable that it produces rapid aging to fully aged condition, however, it does not alter the strength-ductility relationship in fully aged condition.
