通过参考一系列过热液态Fe100−xBx(x=0~100)合金,证实了液态Fe80B20合金配对相关函数第二个峰中肩部的存在。肩部是由于连接方式的机会不平等造成的,而不是特定类型的以B为中心的簇的出现。我们的模型预测以 B 为中心的结构单元的顶点共享和面共享是肩部的两种重要连接模式。这张图可能填补了理解过热液体和非晶态 Fe80B20 合金中第二个峰形状差异很大的空白。
By referencing to a series of superheated liquid Fe100 −xBx(x= 0 to 100) alloys, the existence of the shoulder in the second peak of the pair correlation functions of liquid Fe80B20alloy is confirmed. The shoulder is caused by the unequal opportunity of connection modes rather than the occurrence of particular types of B-centered clusters. Our model predicts that vertex sharing and face sharing of the B-centered structure units are the two significant connection modes responsible for the shoulder. This picture may fill the gap in understanding the widely different shapes of the second peak in superheated liquid and amorphous Fe80B20alloy.
