Abstract

The effects of homogenization treatment on the electrical conductivity, tensile strength and microstructure of Al-B electrician round rod were investigated by means of tensile test, optical microscopy(OM), scanning electron microscopy (SEM), energy dispersive spectroscopy(EDS). The results indicate that during homogenization the grain boundary of samples became thinner, microstructure was more compact and well-distributed. As-cast Al electrician round rod has favorable comprehensive properties under homogenization at 430℃ for 3 h, the electrical conductivity and tensile strength reach to 58.1%IACS and 100MPa, respectively. Compared to the sample without homogenization, the electrical conductivity increased by 2.1%IACS in the case of tensile strength was not reduced. After 83% rolling processing of specimen with better comprehensive performance, the electrical conductivity and tensile strength of samples reach to 55.24%IACS and 209MPa, respectively.
