摘要
设计了一种Al-Fe合金的化学成分,采用半固态技术进行了成形,分析了合金铸态、电磁搅拌态、挤压态的组织,检测了合金铸态、半固态成形态的力学性能。试验结果表明:合金元素的加入和凝固过程中外加电磁搅拌以后,合金组织明显细化;经过半固态成形后,合金组织进一步细化,第二相长度和厚度减小,同时尖角发生钝化,且分布较均匀,力学性能比铸态提高了79.7%。
In this paper, an Al-Fe alloy chemical composition has been designed; semi-solid forming technology has been used to prepare the alloy. The microstructure of the alloy as cast, electromagnetic stirred and semi-solid formation state has been analyzed and the mechanical properties of the alloy have been tested. The results show that microstructure of the alloy becomes obviously thinner after the alloying and electromagnetic stirring, semi-solid formation processing makes the microstructure further refined.
