eutectic cell 共晶系合金在共晶凝固阶段由溶质相与基体相共生生长成的晶粒团。例如铸铁中的奥氏体-石墨或奥氏体-渗碳体共晶团。
随着过热度的增加，碳化物共晶团的尺寸增大，导致室温拉伸性能降低。
As the superheat temperature being enhanced, the size of carbides eutectic cells increases and tensile properties decline at room temperature.
利用单相枝晶状共晶的熔断模型，解释了过冷熔体形成异常粒状共晶团的形成原因。
The reason of formation of anomalous eutectic group can be explained by the model of single dendritic eutectic phase growth and fusion.
实验结果表明，在高频脉冲电流作用下铸铁石墨片细化，石墨片变得卷曲，共晶团尺寸减小。
The results show that high frequency pulse electric current can refine and crinkle graphite flake, decrease the dimension of eutectic cell.
