本文采用粉末冶金技术和微波烧结工艺制备了xAg/Ti-Ta.采用光学和扫描电子显微镜(SEM)、X射线衍射仪(XRD)、压缩试验和形状记忆试验研究了xAg/Ti-30Ta(x=0,0.41 at％,0.82 at％和2.48 at％)形状记忆合金(SMAs)的热力学、力学和生物性能.结果表明,Ag的加入对颗粒的孔径和形状有显著影响,在Ag加入量为0.41 at％时,颗粒的最小孔径为11μm,相对密度为72％.断裂应力和应变随着Ag的增加而增加,Ag加入量为0.41 at％的合金断裂应力应变达到最大.0.82 at％Ag/Ti-Ta表现出更好的耐蚀性和生物相容性,具有与纯Ti和Ti6Al4V合金类似的性能,具备作为生物材料的应用前景.“,”In the present study, the thermal, mechanical, and biological properties of xAg/Ti-30Ta (x=0, 0.41, 0.82 and 2.48 at％) shape memory alloys (SMAs) were investigated. The study was conducted using optical and scanning electron microscopy (SEM), X-ray diffractometry (XRD), compression test, and shape memory testing. The xAg/Ti-Ta was made using a powder metallurgy technique and microwave-sintering process. The results revealed that the addition of Ag has a significant effect on the pore size and shape, whereas the smallest pore size of 11 μm was found with the addition of 0.41 at％ along with a relative density of 72％. The fracture stress and strain increased with the addition of Ag, reaching the minimum values around 0.41 at％ Ag. Therefore, this composition showed the maximum stress and strain at fracture region. Moreover, 0.82 Ag/Ti-Ta shows more excellent corrosion resistance and biocompatibility than other percentages, obtaining almost the same behaviour of the pure Ti and Ti-6Al-4V alloys, which can be recommended for their promising and potential response for biomaterial applications.
