【 摘 要 】

This paper aims to research the effects of progressive solution treatment on property of aluminium alloy electrical round rod, we mainly research the influences of different temperature on tensile strength and electrical conductivity of the aluminium alloy electrician round rod. The component and phase constitution of the aluminium alloy was analysed by means of OLYMPUSPMG-3 horizontal metallurgical microscope, SUPRA40 scanning electron microscope, APOLLO-10Xenergy spectrometer, tensile strength and conductivity of aluminium alloy electrical round rod under various progressive solution treatment. The results show that: comprehensive performance of specimen is optimal by means of scheme(350 °C×1h+510°C×6h), the conductivity is 56.6%IACS and the tensile strength is 103MPa.
