In this study,the microstructural evolution and mechanical properties of a newly developed Ti-40.7Zr-24.8Nb(TZN)alloy after different thermomechanical processes were examined.As-cast TZN alloy plates were solutiontreated at 890℃ for 1 h,after which the thickness of the alloy plates was reduced by cold rolling at reduction ratios of 20%,56%,76%,and 86%.Stress-induced α”formation,{332}<113>β mechanical twinning,and kink band formation were observed in the cold-rolled TZN alloy samples.In the TZN sample after cold rolling at the 86%reduction ratio plus a recrystallization annealing at 890℃ for 1 h,the deformation products of a stressinducedα”phase,{332}<113>β mechanical twinning,and kink bands disappeared,resulting in a fine,equiaxed singleβ phase.The alloy samples exhibited elongation at rupture ranging from 7%to 20%,Young's modulus ranging from 63 to 72 GPa and tensile strength ranging from 753 to 1158 MPa.The TZN alloy sample after cold rolling and recrystallization annealing showed a yield strength of 803 MPa,a tensile strength of 848 MPa,an elongation at rupture of 20%,and an elastic admissible strain of 1.22%,along with the most ductile fractures during tensile testing. 展开更多
