摘要

研究了不同RE含量（0、0.04%、0.05%、0.06%）对锌合金显微组织、力学性能及耐蚀性的影响。在Zn-Al-Cu-Mg合金中加入适量的RE能阻止树枝晶长大

细化晶粒

并能改善合金的力学性能。当RE的加入量为0.05%时

合金的抗拉强度提高了11.8%

伸长率提高了1.75倍

硬度提高了5.6%。加入适量的RE后合金的耐蚀性能也有所提高。

Abstract

Effects of different RE additions including 0

0.04%

0.05% and 0.06% on the microstructure

mechanical properties and corrosion resistantance of the Zn-Al-Cu-Mg alloy were investigated.The results reveal that tensile strength and hardness of the Zn-Al-Cu-Mg alloy are increased by 11.8% and 5.6%

respectively

with appropriate RE addition as a result of refining grain size by restraining growth of dendrite.Meanwhile

corrosion resistance of the alloy can be slightly improved also.
