本文结合铝—钢、铝—铜、铝—不锈钢、低碳钢—不锈钢等双金属带的轧制实验结果与系统的电镜观察,讨论并分析了在同步轧制与异步轧制条件下的复合轧制变形特点及其对初结合状态的影响,以及不同的后续热处理效果。通过分析强调指出,对促进层间结合起决定性作用的因素并非两层相结合金属的整体(平均)变形,而是接触面附近的显微搓剪变形。在一定的变形温度与单位压力的配合
In this paper, aluminum-steel, aluminum-copper, aluminum-stainless steel, low carbon steel-stainless steel bimetallic strip rolling experimental results and the system electron microscopy, discussed and analyzed under synchronous rolling and asynchronous rolling conditions Rolling deformation characteristics and the impact on the initial bonding state, and the effect of different follow-up heat treatment. Through analysis, it is emphasized that the factor that plays a decisive role in promoting interlayer bonding is not the overall (average) deformation of the two-layer combined metal but the micro-shear deformation in the vicinity of the contact surface. In a certain deformation temperature and the unit pressure with
