摘　　要：在多功能热轧机上对广泛应用的代表性金属材料Q235碳素钢和L2铝分别进行了累积叠轧焊实验,重点研究了变形温度、累积叠轧次数和压下量对金属材料强度、应力-应变曲线、显微硬度、塑性的影响规律,分析了规律形成的原因.结果表明Q235碳素钢和L2铝在不加入任何强化元素的情况下完全可以达到良好的自身结合,材料的抗拉强度得到提高,金属材料的塑性分别有不同程度的下降.Accumulative roll bonding （ARB） industrial experiments of Q235 plain carbon steel and L2 pure Al were carried out with a multi-function hot-rolling mill. The effects of deformation temperature, reduction and cycle pass on the tensile strength, stress-to-strain relation, microhardness and plasticity of these two metal mate- rials were investigated, and the reasons for these effects were analyzed. The results indicated that Q235 plain carbon steel and L2 pure Al could be well-bonded themselves by ARB process without the addition of any strengthening elements, their tensile strength increased, but their plasticitv decreased in a certain extent.
