RE 对 ZnAl4 合金组织和力学性能的影响

Effect of RE on Microstructure and Mechanical Property of ZnA14 Alloy

在ZnAl4合金中添加RE元素对其进行变质处理,通过金相组织和力学性能分析,研究了RE对该合金的显微组织和力学性能的影响。结果表明,基体中加入适量的稀土后,优化了组织结构,细化了晶粒,使合金的强度、硬度提10%以上,延伸率也有一定的提高。

RE was added in the ZnAI4 alloy. Through the analysis of its microstructure and mechanical properties, The effect of RE on microstructure and mechanical properties was studied. It has been shown that the organizational structure was optimized and its grains get refinement. Then appropriate amount of rare earth was added. It makes its strength and hardness to increase more then 10% and the elongation have a certain improvement.
