EFFECT OF Cr,Cu AND Co ON MAGNETOSTRICTION OF Fe-Si-B AMORPHOUS ALLOYS

Abstract

Abstract: 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_xC_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 temperature has been studied.It was observed that the saturation magnetostriction of the alloys may be re- markably improved by small addition of Cu and Co.the peak value being 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).

Key words: amorphous alloy, magnetostriction, Fe-Si-B system
