通过在 Fe-Si-B-P 合金体系中微合金化添加Mo 元素,并提高铁含量,成功制备了具有较强非晶形成能力和优异软磁性能的非晶软磁合金.研究发现, Mo 元素微合金化能有效提高合金的非晶形成能力,1％的 Mo 可以将该非晶合金体系的 Fe 含量极限提高到84％以上,从而得到了饱和磁感应强度(B s )高达1．63 T的非晶合金.其中 Fe80 Si4．75 B 9．5 P4．75 Mo 1非晶合金可以铸造形成非晶块体样品,临界直径达到1 mm,饱和磁感应强度达到1．54 T,矫顽力为1．9 A/m.在整个成分范围内,该合金体系都具有1．9~5．1 A/m 的低矫顽力和高于传统 Fe-Si-B 合金的饱和磁感应强度(B s ),具有较好的应用前景.

Based on the Fe-Si-B-P amorphous alloy system,we successfully developed the amorphous alloys with large GFA and excellent magnetic properties by micro-alloying Mo element and increasing Fe content.We found that micro addition of Mo can effectively increase the glass forming ability.With only 1% addition of Mo,the Fe limitation to form a single amorphous phase is increased up to 84% leading to a high B s up to 1.63 T.Addi-tionally,the as designed Fe80 Si4.7 5 B9 .5 P4.7 5 Mo 1 alloy can form a glassy rod with a Dcr of 1 mm exhibiting a high B s of 1.54 T and low H c of 1.9 A/m.Owning to the excellent magnetic properties such as low H c of 1.9-5.1 A/m and higher B s than traditional Fe-Si-B amorphous alloys,the present alloy system is believed to be promising soft magnetic materials for the application in the future.
