摘要
采用钇基重稀土对AlSi7Mg0.3合金进行了细化变质处理,研究了钇基重稀土对合金组织、热处理态力学性能的影响。实验表明: 钇基重稀土能强烈变质AlSi7Mg0.3合金中的共晶硅,同时对初晶α(Al)有明显的细化作用,使合金的力学性能得到大幅提高。
The influences of heavy RE elements on the microstructures and mechanical properties of AlSi7Mg0.3 alloy were researched .The results show that heavy RE elements can remarkablely modify eutectic silicon and refine the primary α(Al), the mechanical properties of the alloy are improved significantly.
