Dataset for "An investigation of the mechanical and microstructural evolution of a TiNbZr alloy with varied ageing time"

Alloys comprised of the highly biocompatible elements titanium, niobium and zirconium have been a major focus in recent years in the field of metallic biomaterials. To contribute to the corpus of data in this field, the current paper presents results from a thorough microstructural and mechanical investigation of Ti-32Nb-6Zr subjected to a variety of ageing treatments. The presented alloy was stabilized to the higher temperature, body-centred cubic phase, showing only minimal precipitation on prolonged ageing, despite the presence of nanoscaled spinodal segregation arising from the Nb-Zr interaction. It further showed excellent mechanical properties, with tensile yield stresses as high as 820 MPa and Young’s moduli as low as 53 GPa. This leads to the ratio of strength to modulus, also known as the admissible strain, reaching a maximum of 1.3% after 6 hours ageing. These results are further supported by similar measurements from nanoindentation analysis.

由高生物相容性元素钛、铌及锆组成的合金，近年来始终是金属生物材料领域的核心研究方向之一。为充实该领域的数据集储备，本文针对经多种时效处理的Ti-32Nb-6Zr合金开展了全面的微观组织与力学性能研究，并呈现相关结果。该合金在高温下稳定为体心立方（body-centred cubic）相；尽管铌-锆相互作用会引发纳米尺度的调幅分解偏析，但长期时效后仅出现极少量析出相。该合金同时展现出优异的力学性能：抗拉屈服强度最高可达820 MPa，弹性模量最低仅为53 GPa。由此得到的强度-模量比（亦称许用弹性应变）在时效6小时后达到峰值1.3%。纳米压痕分析得到的相似测试结果进一步佐证了上述结论。
