摘 要: 通过测试自然时效和人工时效的强度-时间关系曲线,以及采用金相显微镜、透射电镜和扫描电镜观察, 探讨了微量锆对经80℃轧制的Zn-22%Al合金显微组织和力学性能的影响。结果表明, 在低于80℃的温轧温度下时效时,加0.08%~0.32%Zr和不加Zr的Zn-22%Al合金的强度保持不变。锆具有细化Zn-22%Al合金的组织并阻碍时效时晶粒长大和等轴程度降低的作用。 锆还可提高Zn-22%Al合金的强度和时效时力学性能的稳定性。在三个不同含锆量的Zn-22%Al合金中,牶?.18%Zr的合金强度最高,而且最稳定。

Abstract:The effects of Zr on the microstructures and mechanical properties of the as-rolled(80℃) Zn-22%Al alloy have been studied by measuring the curves of tensile strength versus ageing time and by means of OM, TEM and SEM. The results show that the strength of?Zn-22%Al-(0.08%~
0.32%)Zr alloys and Zn-22%Al alloy remains constant after ageing below the warm-rolling temperature(80℃), that Zr can refine the microstructure of Zn-22%Al alloy, slow the grain growth and reduce the equiaxial degree during ageing, and that Zr can improve the strength and the stability of mechanical properties of Zn-22%Al alloy. It is found that the Zn-22%Al-0.18%Zr alloy has the highest strength and is the most stable one among three Zn-22%Al alloys tested with different Zr contents.
