摘要 采用普通对称式方法(不施加复合能场)和非对称下沉式方法(施加超声波/电磁复合能场)对1060铝合金板带坯进行铸轧试验;研究了复合能场对铝合金板带组织和性能的影响。结果表明:施加复合能场后,铸轧速度(1.2~1.4m.min-1)提高了30%,铝合金板带的组织由粗大的柱状晶转变为均匀细小的等轴晶,其抗拉强度、屈服强度、伸长率和硬度分别提高了25.03%,24.37%,40.09%和10.95%。 The roll-casting tests of 1060 aluminum alloy strip were performed by common symmetrical type method (without composite field) and asymmetric and sunken method (compound energy-field with ultrasonic and electromagnetic field). The effects of compound energy-field on microstructure and mechanical properties of the Muminum alloy strip were studied. The results show that, after the composite energy-field was applyed, the castrolling rate (range from 1.2 m · min-1 to 1. 4 mmin^-1) was increased by 30%, mierostructure changed from columnar grains to even and fine equiaxed grains, and the tensile strength, yield strength, elongation and hardness were improved by 25. 03%, 24. 37%, 40. 09%, and 10. 95%, respectively.
