Abstract

By using OP SEM double arm direct electric bridge, electronic universal material testing machine and electric heating high temperature drying box instrument. The effect of Er on the properties and microstructures of Al-Zr-B alloy electric conductors was studied. The results show that additive Er can refine the grain of the alloy, increase the strength of the alloy and heat resistance and conductivity after a reasonable heat treatment. Er can react with impurity elements existing in aluminum matrix to form precipitated phase, thereby the effect of impurity elements on the conductivity of aluminum was reduced, their corresponding the electric conductivity and tensile strength improved. When the Al-0.2Zr-0.06B-0.2Er alloy soaked in the temperature of 220 for 8h, its tensile strength and equivalent conductivity is 218MPa and 59.8%IACS respectively. The complicated properties of Al-Zr resistant alloy wires are improved, this study is of significance.
