本文报道了Fe_(80-x)Cr_xSi_5B_(15),Fe_(80-x)Cr_xC_5B_(15),Fe_(80-x)Cu_xSi_5B_(15)和(Fe_(1-x)Co_x)_(32)Cu_(0.4)Si_(4.4)B_(13.2)四系列非晶合金在室温下的饱和磁致伸缩系数λs随成分x的变化关系,讨论了C,Si,Cr,Cu,Co原子对磁致伸缩系数的影响。发现少量Cu,Co的加入大大提高了非晶合金的λs。特别是(Fe_(1-x)Co_x)_(82)Cu_(0.4)Si_(4.4)B_(13.2)系列中当x=0.02时峰值λs=70×10~(-6)。
The dependence of composition varied, especially C, Si, Cr, CU and Co,in four amorphous alloy systems Fe_(80-x) Cr_xSi_5B_(15), Fe_(80-x) Cr_x C_5B_(15), Fe_(80-x) Cu_xSi_5B_(15) and(Fe_(1-x) Co_x)_(82)Cu_(0.4)Si_(4.4)B_(13.2) upon their saturation magnetostriction at room temperaturehas been studied. It was observed that the saturation magnetostriction of the alloysmay be remarkably improved by smaller addition of Cu and Co, the peak valuebeing up to 70×10~(-6) as x=0.02 in alloys (Fe_(1-x) Co_x)_(82)Cu_(0·4)Si_(4·4)B_(13·2).
