Abstract
In the present study, Ti–29Nb–13Ta-4.6Zr alloys were prepared by cryomilling and spark plasma sintering. Experimental results show that the as-sintered alloys have a fine-grain structured β phase and a small amount of α phase. By optimizing the sintering temperature to 1050 °C, Ti–29Nb–13Ta-4.6Zr alloy with a compression yield strength of 972 ± 18 MPa and an ultimate compression stress of 2071 ± 27 MPa, as well as an ultimate tensile strength of 1034 ± 19 MPa and a plastic strain of 8.7 ± 0.3%, together with a low Young's modulus of 74 ± 2 GPa can be obtained. Additionally, the as-sintered alloys also show preferable corrosion resistance with a low corrosion rate of ∼0.71 μm/year in Ringer's solution.
