摘要
剧烈塑性变形(SPD)能使材料同时具有良好的力学性能和优良的生物相容性能。与传统的钛合金相比,超细晶生物医用钛合金具有更高的强度、更好的耐腐蚀性和抗疲劳性能。重点论述了剧烈塑性变形技术及其在医用钛合金中的应用,详细地阐述了4种SPD细化晶粒方法。
Severe plastic deformation （SPD） can make the material have good mechanical properties and excellent biological compatibility. Compared with traditional titanium alloy, ultrafine-grained biomedical titanium alloy has higher strength, better corrosion resistance and anti-fatigue performance. Severe plastic deformation technique and its application in medical titanium alloy were mainly discussed. Four kinds of SPD grain refinement methods were elaborated in detail.
