用机械合金化的方法制备了Fe50B15Si35纳米粉末,研究了Fe50B15Si35混合粉末在机械球磨过程中结构和磁性的变化。X射线衍射和矫顽力的测量结果表明,粉末的晶粒尺寸随球磨时间的增加而减小,样品的矫顽力随球磨时间变化而变化。
The Fe50B15Si35 nanopowder was prepared by mechanical alloying and the change of structure and magnetism of the Fe50B15Si35 mixed powder during mechanical milling was studied. X-ray diffraction and coercivity measurement results show that the grain size of the powder decreases with the increase of milling time, and the coercivity of the sample changes with the ball milling time.
