碳添加以及退火处理对Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)(x=0、0.5、1、1.5、2、2.5)非晶合金非晶形成能力和软磁性能的影响

Effect of C addition and annealing conditions on the magneticproperties of nanocrystalline Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)(x=0、0.5、1、1.5、2、2.5)ribbons

在不损坏软磁特性的前提下增强非晶形态形成能力,并研究生产新型Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)(x=0、0.5、1、1.5、2、2.5)软磁合金。研究Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)软磁合金的热稳定性以及磁性能,结果分析显示,随着C含量的增加,合金的非晶态形成能力逐渐增强,饱和磁感应强度(Bs)明显提升,软磁特性也有了明显提高。在x=1.5时,Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)性能最佳,Bs为1.75T,矫顽力为2.1A/m。在653K温度下等温退火300s后,随着α-Fe相的析出,整个合金体系的Bs增加,从1.48T-1.75T增加到1.64T-1.83T。在773K等温退火300S后,Bs从1.48T~1.75T增加到1.67T~1.80T。晶化处理后,Fe-(B,P)硬磁相析出,Hc也有所升高。

We report the effect of substituting C for B on the glass formation,magnetic behaviors and thermal properties of Fe_(84)Si_(2)P_(3)B_(10.5-x)C_(x)Cu_(0.5)(x=0,0.5,1,1.5,2,2.5)alloys ribbons.The results show that with the increase of C content,the amorphous forming ability of the alloy was gradually enhanced,and the saturation magnetic induction intensity(Bs)of the alloy was obviously improved.The soft magnetic properties were also obviously improved.When X was 1.5,Fe_(84)Si_(2)P_(3)B_(9)C_(1.5)Cu_(0.5)exhibited good soft magnetic performance that was characterized by a high saturation magnetic flux density of 1.75 T,and the coercivity force Hc was 2.1 A/m.After annealed at 653 K and 773 K for 300 s,the Bs and Hc increased with the precipitation ofα-Fe phase.
