Abstract

The near-α dual-phase Ti-Al-V-Mo-Nb-Zr alloy series were designed and prepared by copper-mold suction casting in this paper. Their compositions fall within the composition framework previously determined for Ti-6Al-4V: the α and β formulas satisfy the ratio of 12:5, but the β part can be further stabilized, by using multi-element alloying and especially by varying the addition amount of Zr, into the form of [Al-Ti_14-_x Zr _x ](Mo_0.6Nb_0.2V_1.2Al), x = 0.6~3. The as-cast alloys are all characterized by a basket-weave microstructure containing a large number of α' martensite needles. With increasing Zr content the α' needles are gradually refined, and the strength and hardness increase accordingly. Among them a Ti-6.7Al-2.2V-2.1Mo-0.7Nb-10.0Zr alloy achieves the ultra-high strength level, with the ultimate tensile strength of 1404 MPa and Vickers-hardness of 451HV, close to the typical ultra-high-strength β-21s after heat-treatment. In comparison with Ti-6Al-4V prepared in the identical conditions, the strength and hardness of this alloy exceeds those of Ti-6Al-4V by 52% and 39%, and the specific strength and hardness are increased by 45% and 33% respectively.
