Abstract At present, the composition of metastable β-titanium alloys is developing towards higher β-stable elements and higher Al content. In this work, Ti-Al-(Mo, Nb, V) metastable β-type alloys were first designed via higher Al content and Mo, Nb and V co-alloying after analyzing the composition of typical metastable β-Ti β-21S and TB18, and prepared by copper-mold suction-casting method. It was found that Ti-6.5Al-1.5V-11.5Mo-2.8Nb alloy possesses a critical stable β-phase structure at as-cast state. At this time, this alloy shows excellent tensile yield strength of 623 MPa and elongation of 16.6%, with the best comprehensive mechanical properties, of which its yield strength is slightly lower than that of the reference TB18 alloy, but the elongation is significantly higher than those of same alloy series and TB18 alloy. In addition, its solidification ranges is 31 ℃, which is lower than that of the same series of alloys, particularly much below the 238 ℃ of TB18 alloy.

Key words： metastable β-titanium alloy high Al content microstructure mechanical property
