摘　　要：以Co-Sb合金为对象,研究了定向凝固过程中合金的组织演变过程,分析了不同凝固速率对合金组织的影响。结果表明,定向凝固速度为2μm/s时,合金凝固组织只有后续凝固的Sb和包晶相CoSb3两相。Taking Co-Sb alloy as research object, the structure evolution process of Co-Sb alloy in the process of directional solidification was studied, the effect of different solidification rates on the microstructure were analyzed. The results show that, when the directional solidification rate is 2 μm/s, the solidification structures of the alloy only have two phases of the subsequent solidification phase Sb and peritectic phase CoSb3.
