| 摘 要： | 采用铜模吸铸法制备直径为3,6 mm的Ti64Fe18Cu18,Ti68Fe18Cu16,Ti70Fe18Cu12和Ti74Fe18Cu84种Ti-Fe-Cu合金圆棒,通过X射线衍射仪和光学显微镜观察该合金样品的微观组织结构,并对其进行压缩实验和抗腐蚀性能测试,研究合金样品的力学性能、抗氧化性能及耐腐蚀性能。结果表明:制备的Ti-Fe-Cu合金相主要是由立方cp2 Ti(Fe,Cu)金属间化合物和bccβTi固溶体组成;随着Cu含量的减少,Ti-Fe-Cu合金硬度和室温塑性逐渐增大,且最大压缩塑可达18%;此合金具有良好的抗氧化和抗腐蚀性能,与传统的Ti-6Al-4V合金相比,其制造成本更低,性能更优异。

| Abstract: | Ti64Fe18Cu18, Ti68Fe18Cu16, Ti70Fe18Cu12 and Ti74Fe18Cu8 alloys with a diameter of 3 and 6 mm were prepared by casting copper mould. Phase composition and micro-structure were studied by OM and XRD. Then, mechanical properties, inoxidability and corrosion resistance were investigated by compression tests and the electrochemical corrosion. The results show that the Ti-Fe-Cu alloys are organized primarily by the intermetallic compound of Ti（Fe, Cu） and β-Ti base disordered solid solution; And with the Cu content reduced, room temperature compression plasticity increases, which reaches 1 8% maximum; These alloys have good inoxidability and corrosion resistance. Compared with conventional Ti-6Al-4V alloy, Ti-Fe-Cu alloys have not only lower manufacturing costs, but also superior performance. |
