Ti-15-3(Ti-15V-3Cr-3Sn-3Al) and two other alloys which contained less V and Cr and more Al than Ti-15-3 were studied to investigate the effects of alloying elements, Al, V and Cr, on beta transus temperature, aging behavior and mechanical properties. The variation in composition causes a little increase in the beta transus temperature and the nose temperature. At full-aged condition, it produces a slight increase in hardness and large increase in alpha phase volume fraction. Among the effects, it is notable that the variation in composition produces rapid aging to full-aged condition, but it does not alter the strength-ductility relationship in full-aged condition. Hence, in Ti-15-3, the adjustment of composition as adopted in this study can widen 'processing window' to attain the required properties.
