摘要
对Ｆｅ７３．５Ｃｕ１ｎｂ３Ｓｉ１３．５Ｂ９成分的母合金进行了机械球磨，并对不同时间的球磨样品进行了Ｘ射线衍射（ＸＲＤ）和Ｍｏｓｓｂａｕｅｒ谱（ＭＳ）的测量，结果表明样品难以完全非晶化，形成了无序的αＦｅ－Ｓｉ固溶体的纳米晶，晶粒尺寸在５ｎｍ左右，同时共存一部分富集Ｎｂ，Ｂ元素的界面非晶相。在各种球磨条件下对αＦｅ－Ｓｉ固溶体中的Ｓｉ含量进行了计算。
Precusor of alloy with normal composition of Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9 has been ball-milled.The unmilled and milled samples for various times have been submitted to the X-ray diffraction and Mossbauer measurement.The results show that the crystalline sample is hard to be amorphizied completely, as a result, a co-existence state with both the nanocrystallites of αFe-Si solid solution, with a grain size of about 5nm, and a interfacial amorphous phase enriched with Nb, B elements has been formed. The Si concentration in the αFe-Si have been calculated.
