摘要
在室温下，用Mossbauer谱和透射电子显微镜（TEM）考查了纳米晶Fi(74.7-x)Cu(0.8)Nb2VxSi(11.5)B(11)（x=1．2，1．5，2．0）合金的显微组织．研究了V对α-Fe（Si）晶粒的体积分数、平均直径、α-Fe（Si）中的出含量以及合金性能的影响，对实验结果作了初步的定性解释．
Microstructures of nanocrystalline Fe74.7-xCu0.8Nb2VxSi11.5b11 (x = 1.2, 1 .5, 2.0) alloyare investigated by Mossbauer Spectroscopy and TEM at room temperatllre. Influence ofV content on the values of volume fraction and average diameter and St content of a--Fo f St)mpstallites as well as properties of this alloy is studied, the results are qualitatively interpreted.
