The effects of cold-rolling with different reduction ratios of 70%-90% on the microstructure and mechanical properties of Ti50Zr30Nb10Ta10 alloy were investigated. It was found that the β-Ti phase in this alloy was stable under cold-rolling. With the increase in reduction ratio from 70% to 90%, the microstructure of the alloys evolved from deformed dendrite structure to fiber-like structure. The alloy cold-rolled with the reduction ratio of 70% exhibited optimum mechanical properties of combined high fracture strength of 1012 MPa and plastic strain of 10.1%, which are closely correlated with the dendrite structure of the alloy. It is indicated that the proper cold-rolling is an effective way to improve the mechanical properties of the titanium alloy.

Microstructure And Mechanical Properties

The novel titanium alloys were investigated in this article. The Ti-3573 and Ti-3873 titanium alloys were cold rolled and aged for different times at 650°C. The microstructure and mechanical properties of the samples were observed and measured, respectively. The results show that the mechanical properties of Ti-3873 alloys were better than those of Ti-3573 alloys. The cold rolling accelerated the α phase precipitation effectively. Stress-induced martensitic transformation was observed in both titanium alloys after cold rolling and aging treatment. Better aging strengthening effect can be obtained for the Ti-3873 titanium alloy which contains more molybdenum element, it is attributed to the role of Mo as β phase stable elemen. The tensile strength of Ti-3873 titanium alloy after aging for 3h reached the maximum value (1314MPa).
