摘要:: 随着生物医用金属材料的市场应用快速增加，生物医用钛及钛合金已成为人体植入物的主要原料，然而相比于不锈钢及钴基合金，常规钛及钛合金虽在生物医用领域各方面性能都较为优异，但作为植入物处于人体较为复杂的环境中时，其各方面性能还有待提高。因此，超细晶钛及钛合金的研发在医用市场具有广阔的前景。目前，市场上超细晶金属材料的制备以剧烈塑性变形工艺为主，其中等通道转角挤压变形的制备方式较为成熟。对生物医用超细晶钛和钛合金的类型及特点作了简单的介绍，着重从等通道转角挤压变形方式制备的超细晶钛及钛合金在生物医学上的耐蚀性、生物相容性、力学性能及疲劳性能等方面进行了简述，对其在医疗市场的未来发展趋势作出了展望，并总结了其未来发展待解决的问题。

Abstract:: With the rapid increase of biomedical metal materials in the market, biomedical titanium and titanium alloys have become the main raw materials for human implants. However, the performance of conventional titanium and titanium alloys compared with stainless steel and diamond-based alloys in various aspects in the medical field is excellent, but its performance as an implant in the more complex environment of the human body needs to be improved. Therefore, the research and development of ultrafine-grained titanium and titanium alloys have great practical significance and broad market prospects in the medical market. At present, the preparation of ultrafine-grained metal materials on the market is mainly based on the severe plastic deformation process, and the equal channel angular pressing deformation method is more mature. This article briefly introduces the types and characteristics of biomedical ultrafine-grain titanium and titanium alloys, focusing on the biomedical corrosion resistance, biocompatibility, mechanical property and fatigue performance of ultrafine-grained titanium and titanium alloys prepared from equal channel angular pressing deformation method. Meanwhile the future development trend of biomedical ultrafine-grain titanium and titanium alloy in the medical market, and the problems to be solved are introduced.
