摘　　要：研究交变电磁场对Al-5%Fe组织性能的影响,得到交变磁场对铸件的组织及力学性能的影响规律。研究结果表明:交变磁场电流强度对铸件的组织及力学性能都有较大的影响。随着通入电流强度的增大,铸件的抗拉强度和伸长率增高、硬度增大,组织结构明显细化。当磁场电流强度为12 A时,抗拉强度和布氏硬度分别提高了143 MPa和88.15 HB,伸长率提高了21.1%,但当磁场电流强度超过12 A时,抗拉强度及硬度反而降低,晶粒变得粗大。The microstructure and property of A1-5%Fe alloy under different alternating magnetic field conditions were examined for the discipline. Effects of alternating magnetic field on microstructures, hardness, tensile strength were studied. The results show that the alternating magnetic field current has an influence on the microstructure and mechanical properties of castings. With the increase of magnetic current strength, the tensile strength, hardness and elongation increase and the grain refines obviously. When the magnetic field current strength is 12 A, tensile strength, brinell hardness and elongation are increased by 143 MPa, 88.15 HB and 18.8%, respectively, but when the magnetic field current strength is more than 12 A, tensile strength decreases, the grain becomes bulky.
