基于d-电子合金设计理论和JMatPro软件，运用正交试验，设计了具有较低弹性模量和较高强度且含有无毒元素Nb、Mo、Zr 和 Sn的新型生物医用β钛合金Ti?35Nb?4Sn?6Mo?9Zr，并对该合金的显微组织和力学性能进行分析。结果表明，Ti?35Nb?4Sn?6Mo?9Zr 合金在800°C 下固溶处理后，由单一的β等轴晶构成。与Ti?6Al?4V相比，该合金具有较优越的力学性能：E=65 GPa，σb=834 MPa，σ0.2=802 MPa，δ=11%，有望成为新型种植材料。该方法可以有效地降低实验次数，并得到理想的实验结果。

A new kind ofβbiomedical titanium alloy, Ti?35Nb?4Sn?6Mo?9Zr, composed of non-toxic elements Nb, Mo, Zr and Sn with lower elastic modulus and higher strength was designed based on d-electron alloy design theory and JMatPro software using orthogonal experiment. The microstructure and basic mechanical properties of designed alloy were investigated. The results show that the alloy is composed of singleβequiaxed grains after solution treatment at 800 °C. Compared with Ti?6Al?4V, the mechanical properties of the designed alloy are more excellent: E=65 GPa, σb=834 MPa, σ0.2=802 MPa, and δ=11%, which is expected to become a promising new type implanted material. The research approach adopted can reduce the experimental time and cost effectively, and get the ideal experimental results.
