研究了B2金属间化合物煤基二元Co-AI合金的显微组织和力学性能。重点研究了含Co初生固溶体的复合材料的两相合金，以期使本脆复合材料具有一定的延展性。首先通过差热分析和能量色散x射线光谱对富钴侧的Co-Al二元相图进行检查，以确定感兴趣的稳定相场。然后对选定的两相合金进行了压缩试验，研究了0.2%流变应力和压缩塑性与微观组织的关系
Microstructure and mechanical properties are investigated in the binary Co-AI alloys based on B2 intermetallic compound CoAl. The effort is focused on two-phase alloys of the compound with Co primary solid solution in order to irnpart some ductility to the intrinsically brittle compound. The Co-Al binary phase diagram on the Co-rich side is first examined to confirm the stable phase fields of interest by differential thermal analysis and energy dispersive X-ray spectroscopy. Then the compression tests are carried out on selected two-phase alloys to correlate the 0.2% flow stress as well as compressive ductility with microstructures
