摘　　要：以新型近β型医用钛合金Ti-5Zr-6Mo-15Nb(TLE)铸锭为实验原料,通过开坯、锻造、轧制、热处理等多道工序制成板材和棒材。分析了不同加工工艺及热处理制度对合金组织与性能的影响。结果表明:TLE合金具有较高的强度、较低的弹性模量、优良的塑韧性与疲劳性能,冷热加工性能好;合金经过适当的固溶与时效处理后可获得良好的综合力学性能匹配,特别适合充当外科植入物材料使用。Ti -5Zr -6Mo - 15 Nb （TLE） titanium alloy is a new near β type titanium alloy. The processability of the new near β type titanium alloy TLE was summarized. The contrast experiments of its mechanical properties under different heat treat conditions were investigated. The TLE alloy has a high strength, low Young＇s moulds, with better plasticity, ductility, and fatigue property. The TLE has a workability under both high and low temperature conditions. After proper solution and age treatment, TLE express a well mechanical properties match. So, the TLE suit for using as a medical implant material.
