Study on the Deformation Rule and Mechanical Properties of Three Layers Aluminum Alloy Plate by Roll Bonding

采用"热轧+中间退火+冷轧+轧后退火"法复合轧制AA1100/AA7075/AA1100三层铝合金板.利用金相、SEM-EDS观察微观组织变化及界面元素扩散,由显微硬度和拉伸试验测定复合板力学性能.结果表明,AA7075层组织呈拉伸纤维状沿轧向分布;热轧包覆率不变,中间退火后包覆率随冷轧应变的增加先减小后几乎不变;结合界面处存在Mg、Zn元素扩散.轧后退火使复合板强度降低、塑性增加,硬度沿厚度方向呈现梯度变化规律.
