| 摘 要： | 利用纳米压入测量仪测试了Ti-12Mo-6Zr-2Fe钛合金的硬度和模量.测试表明,Ti-12Mo-6Zr-2Fe钛合金的硬度比Ti-6Al-4V ELI高,而模量比后者低,与常规方法得到的规律一致,表明该方法能很好地表征钛合金的力学特性.对测试过程的分析表明这种方法得到的结果不能与传统方法得到的结果互换,表面状态对测量结果有一定影响.

| Abstract: | The hardness and elastic modulus of Ti-12Mo-6Zr-2Fe titanium alloy have been inspected by means of nanoindentation. It showed that the hardness of Ti-12Mo-6Zr-2Fe is higher than that of Ti- 6Al-4V ELI, while the elastic modulus of Ti-12Mo-6Zr-2Fe is lower than the that of Ti-6Al-4V ELI, this results consist with the rule obtain by conventional testing method. The nanoindentation method can describe the mechanical properties of titanium alloys, hut its results could not transfer to conventional tested results, and the surface status of the specimen has some kind of effect on the testing results. It is highly advantageous to evaluating the mechanical properties of titanium alloys by means of nanoindentation method. |
