【Abstract】 Compared with conventional alloys, new multi-principal component high entropy alloys(HEAs)show better properties such as high strength, high wear resistance and high corrosion resistance due to high configuration entropy. HEAs are expected to overcome the shortcomings of traditional alloys in the medical industry. Therefore, HEAs holds significant academic research value and considerable application potential. Research status of elements screening, phase prediction and biocompatibility of medical titanium based HEAs were summarized in this paper. Furthermore, composition design idea of medical titanium based HEAs are briefly introduced, and the disadvantages of HEAs in application are pointed out. Finally, the future development trend of HEAs is prospected.更多还原
