摘　　要：镁/铝复合板具有密度小、比强度高和耐腐蚀性好等优点,广泛应用于航空航天、汽车制造等领域。轧制法是目前生产镁/铝复合板最为广泛的一种方法,该法设备简单、操作容易、成本低廉。介绍了普通轧制法、异步轧制法、爆炸+轧制法、累积叠轧法、固-液铸轧法、波-平轧制法6种轧制工艺,以及这些工艺在制备镁/铝复合板时的优缺点。波-平轧制工艺可以提高复合板的平直度,有利于板材后续加工成形。也研究了轧制温度、轧制压下率、轧制速度、轧后退火处理对镁/铝复合板力学性能的影响,镁/铝界面金属间化合物的形成因素,以及化合物层厚度对镁/铝复合板力学性能的影响。Mg/Al clad plates are widely used in aerospace and automobile manufacturing industries due to the advantages of low density, high specific strength and good corrosion resistance. Rolling technique is one of the most widely used methods in the production of Mg/Al clad plates, which has the advantages of simple equipment, easy operation and low cost. Six rolling processes were introduced, including common rolling, asynchronous rolling, explosion + rolling, accumulative rolling,solid-liquid casting rolling and corrugated-flat rolling. The advantages and disadvantages of these processes in preparing Mg/Al clad plates were also studied. Corrugated-flat rolling process improved the flatness of the clad plates, which was conducive to the subsequent processing and forming of plates. The effects of rolling temperature, rolling reduction ratio, rolling speed and annealing treatment on the mechanical properties of Mg/Al clad plates, the formation factors of intermetallic compound at Mg/Al interface and the influence of intermetallic compounds thickness on the mechanical properties of Mg/Al clad plates were also analyzed.
