摘要

本研究探讨了通过调整 Al-Zn-Mg-Mn 合金中的硒添加量来改善导电性和机械性能的问题。Sr 的添加形成了金属间化合物，金属间化合物的体积分数随着 Sr 含量的增加而增加。随着 Sr 添加量从 0% 增加到 1.0%，挤压合金的导电率分别下降到 48.9%、45.2% 和 42.5% IACS。随着锶添加量的增加，轧制合金的平均晶粒尺寸分别减小到 55.5、53.1 和 42.3 μm。极限抗拉强度分别提高到 195、212 和 216 兆帕。

Microstructural, Electrical and Mechanical Properties of the Al-Zn-Mg-Mn Alloy with Strontium Addition

This study investigated the improvement in the electrical conductivity and mechanical properties obtained by adjusting the amount of the Sr addition to the Al-Zn-Mg-Mn alloy. The addition of Sr formed an intermetallic compounds, and the volume fraction of the intermetallic compounds increased with increasing Sr content. As the amount of Sr added increased from 0 to 1.0 wt%, the electrical conductivity of the extruded alloy decreased to 48.9, 45.2 and 42.5% IACS. As the addition amount of Sr increased, the average grain size of the rolled alloy decreased to 55.5, 53.1 and 42.3 μm. And, the ultimate tensile strength increased to 195, 212 and 216 MPa.
