Complex Analysis of Electrical Resistivity Dynamics of Co₈₂Fe₄Cr₃Si₈B₃ Amorphous Alloy under Heat Treatment

Abstract:

In this paper the detailed analysis of thermal behavior of electrical resistivity of Co₈₂Fe₄Cr₃Si₈B₃ amorphous alloy is made. It has been shown that within temperature range 23⁰С <T< 560⁰С the structure of the alloy keeps its amorphous character and only a slight changes occurred. A high temperature (above room temperature) resistivity minimum was found at 160°C. This feature was related with Curie temperature of the alloy. It has been shown that change of electrical resistivity behavior at 350°C can be explained by reaching the Debye temperature of the alloy.
