摘要：为了研究按摩尔分数（FeAl）1-xNix(x=0.4,0.6)和（FeAl3）1-xNix(x=0.1,0.3)配比的粉体在机械合金化过程中的结构演变,采用X射线衍射(XRD)对球磨样品进行分析。结果表明:球磨50h后的产物主要由Fe和Al的原子比来决定,Ni的成分含量大小对主要产物基本没有影响。

Abstract：In order to research the structural evolution of the elemental powders of （FeAl）1-xNix （x=0.4， 0.6） and （FeAl3）1-xNix （x=0.1， 0.3） obtained by mechanical alloying， X-ray diffraction （XRD） were used to analyze the as-prepared samples. The experimental results showed that the last milling products were decided by the proportion of atom between Al and Fe in the powder and the Ni content in the power had not affected to the main products.
