摘要

通过金相组织分析以及在不同参数下以锶变质对压铸铝合金性能带来的各种影响进行了试验。结果表明对压铸铝合金而言

在快速凝固的条件下

不推荐以锶作变质处理

但须根据铸件的结构特征和特定需要加以区别对待

Abstract

Different influence of Sr modification with different parameters by analyzing metallographic structure on properties of die casting Al alloy is studied.The results show that Sr modification should not be taken in rapid solidification for die casting Al alloy

but it is necessary to take different consideration in the light of structure characteristics and special demand for castings.
