【摘要】 采用机械合金化方法，制备了ε－ ＦｅＸＮ／ＢＮ 磁性纳米复合材料，并用Ｘ 射线衍射仪和振动样品磁强计分析了α－ Ｆｅ 与ＢＮ 混合粉末的结构和磁性随球磨时间的变化．结果表明，这种原料通过球磨先形成非晶合金，然后非晶合金晶化形成了ε－ ＦｅＸＮ／ＢＮ，其饱和磁化强度随球磨时间的增加有一最大值，随后逐步减小更多还原

【Abstract】 The magnetic nanocomposite ε-Fe XN/BN was prepared by mechanical alloying.The change of structure and magnetism of the sample with ball milling was analyzed by x-ray and vsm.The results indicated that mixed powders non-crystallined,and then formated ε-Fe XN/BN alloy.The saturation magneization of sample increded,and then decreased with ball milling time. :The magnetic nanocomposite ε-Fe XN/BN was prepared by mechanical alloying.The change of structure and magnetism of the sample with ball milling was analyzed by x-ray and vsm.The results indicated that mixed powders non-crystallined,and then formated ε-Fe XN/BN alloy.The saturation magneization of sample increded,and then decreased with ball milling time.更多还原
