本文主要通过用3％at的Cr或Mo原子部分取代Fe_(79)Si_(11)B_(10)非晶合金中的Fe原子,研究了Cr或Mo原子对Fe基非晶高频损耗及静态磁性能的影响。结果发现:Fe_(79)Si_(11)B_(10)、Fe_(76)Cr_3Si_(11)B_(10)和Fe_(76)Mo_3Si_(11)B_(10)非晶合金分别在425℃、475℃和500℃左右退火后,其高频损耗P_(2/20K)分别是16-17w/kg、13-15w/kg和12—14w/kg。根据透射电镜观察和X射线衍射分析结果,我们认为:Fe_(76)M_3Si_(11)B_(10)非晶(M=Fe、Cr、Mo)的高频损耗性能改善可以归结于非晶表面的部分晶化作用。
In this paper, the effect of Cr or Mo atoms on the high frequency loss and static state of Fe-based amorphous alloys was studied by partially replacing Fe atoms in Fe 79 Ga 11 B 10 amorphous alloys with 3% at Cr or Mo atoms. Effect of magnetic properties. The results show that Fe_ (79) Si_ (11) B_ (10), Fe_ (76) Cr_3Si_ (11) B_ (10) and Fe_ (76) Mo_3Si_ (11) B_ (10) After annealing at about 500 ℃, P_ (2 / 20K) is 16-17w / kg, 13-15w / kg and 12-14w / kg, respectively. According to the results of TEM and X-ray diffraction analysis, we think that the improvement of high frequency loss properties of Fe 76 M 3 Si 11 B 10 amorphous (M = Fe, Cr, Mo) can be attributed to the amorphous surface Partial crystallization.
