The effect of Aluminum equivalent and Molybdenum equivalent on the strength and fracture toughness of titanium alloys was studied in this paper. The result shows that the tensile strength of the alloy increases with increasing of aluminum equivalent and molybdenum equivalent and the fracture toughness decreases gradually, the effect of aluminum equivalent is comparatively more conspicuous. A suitable value range of aluminum equivalent and molybdenum equivalent of high strength and high toughness titanium alloys are obtained from the analysis, based on this, a new type of high strength and high toughness titanium alloy BTi-6554 (Ti-4Al-5Mo-5V-6Cr) was developed, which has good combination of strength and fracture toughness and has the characteristics of high strength and high toughness.
