摘要

采用真空电弧非自耗熔炼方法制备Ti45Al-8Nb-0.3Y-mCo (m=0, 0.5, 1, 2, 原子分数/%, 下同)合金, 研究合金的组织和高温抗氧化性能。结果表明: Co能够明显细化TiAl-Nb合金组织, 但对合金中α₂+γ片层组织的形成具有较强烈的抑制作用, 并且会促进富Co的B₂相析出。Ti45Al-8Nb-0.3Y-mCo合金在1000 ℃空气中氧化100 h后形成的氧化膜均主要由较为疏松的TiO₂和Al₂O₃混合组成, 且TiAl-Nb-0.3Y合金的氧化增重随Co含量增加而增大, 但氧化膜的抗剥落能力随Co含量增加而明显提高; 添加Co能够在一定程度上降低氧化膜的内应力, 对提高其抗剥落性能有益, 但引起的粗大B₂相析出削弱了合金的高温抗氧化性能。

Abstract：

Ti45Al-8Nb-0.3Y-mCo (m=0, 0.5, 1, 2, atom fraction/%) alloys were prepared by vacuum arc non-consumable melting method. The microstructure and high temperature oxidation resistance of the alloys were investigated. The results show that the microstructure of TiAl-Nb alloy can be significantly refined by addition of Co element. However, Co can remarkably inhibit the formation of α₂+γ lamellar while promote the formation of Co-rich B₂ precipitations in the alloys. The oxide films formed on the Ti45Al-8Nb-0.3Y-mCo alloys mainly consist of relatively loose TiO₂ and Al₂O₃ mixtures, after oxidation at 1000 ℃ for 100 h in air. With the increase of Co content, the mass gains of the TiAl-Nb-0.3Y alloys after oxidation increase obviously, while much better anti-spalling performance of the oxide films can be obtained. Addition of Co can reduce the internal stress of the oxide film to a certain extent, which is beneficial to the anti-spalling performance of the oxide film. However, the coarse B₂ precipitation caused by Co weakens high temperature oxidation resistance of the alloy.

Key words： TiAl-Nb alloy Co alloying alloy microstructure high temperature oxidation
