摘    要:研究Co-Ti-Ta三元系富Co区的相平衡。显微组织和XRD分析以及EDS检测结果表明,在1000~1200℃温度范围内,L12结构Co3Ti相和Laves_36_Co3Ta相与α-Co构成相平衡。Co3Ti相中Ta的固溶度超过10%,Ta的加入使Co3Ti相更稳定。根据实验结果构建Co-Ti-Ta三元系富Co区在1000、1100和1200℃等温截面图。

关 键 词:L12型金属间化合物  相平衡  Co-Ti-Ta  钴基高温合金

Abstract:The phase equilibria in Co-rich region of Co-Ti-Ta system were studied. The microstructure and XRD analysis together with EDS determination show that L12 type Co3Ti phase and Laves_C36_Co3Ta phase get equilibrium with α-Co phase from 1 000 to 1 200 °C. The Co3Ti phase possesses a solubility of Ta higher than 10%, and the addition of Ta stabilizes the Co3Ti phase. The isothermal sections of the Co-Ti-Ta system in the Co-rich region at 1 000, 1 100 and 1 200 °C were constructed according to the result.
Keywords:L12 type intermetallic compound  phase equilibrium  Co-Ti-Ta  Co-based superalloys
