美国能源部洛斯阿拉莫斯国家实验室开发了一项通过改变钛的晶粒大小获得高强纯钛植入件的技术。目前，钛铝钒合金由于高强性能已用于医疗植入件。但合金元素的毒性引起了人们的关注，这种毒性可能引起癌症和神经紊乱。不仅如此，最近的实验表明，钛铝钒植入件不加纯钛适合骨头?
The US Department of Energy Los Alamos National Laboratory has developed a technology to obtain high-strength pure titanium implants by changing the grain size of titanium. At present, titanium-aluminum-vanadium alloys have been used for medical implants due to their high strength properties. However, the toxicity of alloying elements has attracted people’s attention. This toxicity may cause cancer and neurological disorders. Not only that, recent experiments have shown that titanium-aluminum-vanadium implants do not add pure titanium for bones?
