摘　　要：采用金属型铸造、电磁搅拌成型以及半固态挤压成型三种方式制备了Al-5.6Fe-4.0Cu-2.0Zn-0.5Mn-0.5Mg合金,通过扫描电镜和透射电镜观察了微观组织,并进行了力学性能测试。结果表明,半固态成型后的铝铁合金组织细化,力学性能大大提高,抗拉强度提升至279 MPa。Al-5.6Fe-4.0Cu-2.0Zn-0.5Mn-0.5Mg alloy was prepared by metal mold casting, electromagnetic stirring molding and semi-solid extrusion molding. The microstructure was observed by SEM and TEM, and the mechanical properties were tested. The results show that the microstructure, mechanical properties and tensile strength of semi-solid Al-Fe alloy are improved greatly, the tensile strength is increased to 279 MPa.
