摘　　要：采用常规双辊铸轧和施加电磁外场的电磁铸轧两种方法对6016铝合金进行铸轧实验;研究施加电磁场对6016铝合金铸轧板微观组织和力学性能的影响。结果表明,与常规铸轧相比,电磁铸轧明显抑制宏观偏析,晶粒细化、大小更均匀,第二相粒子分布更弥散,力学性能显著提高。电磁铸轧板坯的抗拉强度、屈服强度和伸长率分别提高了13%、27%、71%。The roll-casting tests of 6016 aluminum alloy strip were carried out by general roll-casting and roll-casting with electromagnetic field. The effect of electromagnetic field on microstructures and mechanical properties of the aluminum alloy strip was studied. The results show that the macrosegregation of electromagnetic casting is obviously inhibited with the original microstructure, the grain is apparently refined and the distribution of the second phases are more diffuse. The mechanical properties are obviously improved, the tensile strength, yield strength and elongation are increased by 13%,27% and 71%, respectively.
