摘要

利用显微组织拓扑转换方法

建立了亚共晶Al-Si合金显微组织特征参数和其电导率之间的本构方程

可以综合考察变质处理和细化处理的效果。细化处理和变质处理之所以提高亚共晶Al-Si合金的电导率

是因为改善了亚共晶Al-Si合金显微组织特征参数。

Abstract

With topological transformation method

the constitutive equation between electric conductivity and microstructure characteristics parameters of hypoeutectic Al-Si alloys is put forward

by which the synthetical effects of refinement and modificaion could be evaluated. The effects of refinement and modification on electric conductivity of A356 alloy are investigated. It is showed that both refinement and modification could improve electric conductivity by changing microstructure characteristics parameters of hypoeutectic Al-Si alloys
