本文首先计算出Fe-Al合金中在任一给定的浓度下,各种有序度所对应的原子在晶格上的分布情况。然后对测量的Mossbauer谱线进行分解,得出合金中原子配位状况。将实验值与计算值进行比较,最后测定出合金的长程有序参数,并对实验及计算结果进行了讨论。
The distribution of atoms in lattice corresponding to different degree of order was calculated for Fe-Al alloy under given concentration. The atom co-ordination of the alloy may be resulted from analysis of the Mossbauer spectra obtained. The long-range order parameter of the alloy is then determined with comparison between the measured and calculated values. A brief discussion on these values has been also made.
