Ti-27Mo-1.5Nb无磁不锈定膨胀合金研究

Research on non-magnetic and stainless controlled expansion alloy Ti-27Mo-1.5Nb

研究了一种Ti-27Mo-1.5Nb新型无磁不锈定膨胀合金,该合金的膨胀系数为7.70×10-6/℃,磁导率为1.0003,同时研究了Ti-27Mo-1.5Nb合金的微屈服强度及其它机械性能和物理性能,该合金还是良好的耐腐蚀材料,试验表明,Ti-27Mo-1.5Nb合金是诸如静电陀螺等电真空领域中与高纯Al2O3匹配的良好封接材料。

A new non-magnetic controlled expansion alloy Ti-27Mo-1.5Nb were designed.The expansion coefficient is 7.70×10-6/℃. The permeability is 1.0003. At the same time,the microyield strength,the physical properties and the mechanical properties of Ti-27Mo-1.5Nb alloy has been studied. The alloy is a fine resistance to corrosion material too. The results indicated that Ti-27Mo-1.5Nb alloy is a fine joining materials to pure Al2O3 ceramic or glass for example electrostatic gyroscope.
