通过对液态铝 - 铁合金结构因子中预峰的位置和高度的研究，发现相图中几乎所有高熔点金属间化合物聚集的区域内预峰高度较高，在[此处可能缺失具体位置信息]处最高；而预峰位置则较小，在[此处可能缺失具体位置信息]处最小。这些结果揭示了液态结构与铝 - 铁合金相图之间的密切关系。构建了两种原子构型，并且发现预峰的起源是铁 - 铁关联、铝 - 铝关联，或者是在不同成分下它们的混合。
Based on the study of the positions and heights of the pre-peaks on the structure factors of liquid Al-Fe alloys, it is found that the heights are higher in the region on the phase diagram where nearly all the intermetallic compounds with higher melting temperature gather, and the highest at ; while the positions are smaller, and a minimum at . These results reveal the close relationship between the liquid structure and the Al-Fe alloy phase diagram. Two types of atomic configuration are constructed, and the origin of the pre-peaks is found to be the Fe-Fe correlation or the Al-Al correlation, or their mixture at different compositions.
