摘要：

为了提高建筑用镁/铝复合板的综合力学性能，分别采用波纹+平辊和平辊+平辊两种轧制条件，同时，在温度为 250、300、350和400 ℃下对镁/铝复合板进行轧制，然后，对其进行显微组织观察并测试各项力学性能参数。研究结果表明：在温度为 350 ℃ 下轧制的镁/铝复合板均形成了良好的结合界面，且未观察到缺陷结构；逐渐提高轧制温度后，形成了更大的镁合金晶粒。随着轧制温度的升高，轧制镁/铝复合板的拉伸强度表现为先增大后减小的变化规律，最大值发生在350 ℃处；伸长率表现为单调增大的变化规律，采用波纹+平辊轧制条件形成了平整的拉伸断口组织，从而使镁/铝复合板具备良好的结合性能；弯曲强度表现为先增大后减小的变化规律，最大值发生在350 ℃处。相比较平辊+平辊方式，采用波纹+平辊方式轧制的复合板强度更高，可见，波纹+平辊轧制能进一步提高复合板的耐弯曲性能。

In order to improving the comprehensive mechanical properties of Mg/Al composite plate for building, the Mg/Al composite plate was rolled under two rolling conditions of corrugated and flat rolling and flat and flat rolling, and the rolling temperatures were controlled at 250, 300, 350 and 400 ℃. Then，the microstructure was observed and the mechanical property parameters were tested of Mg/Al composite plate. The results show that the Mg/Al composite plates rolled at the rolling temperature of 350 ℃ have good bonding interfaces, and no defect structure is observed. After gradually increasing the rolling temperature, larger magnesium alloy grains are formed. With the increasing of rolling temperature, the tensile strength of rolled Mg/Al composite plate increases first and then decreases, and the maximum value occurs at 350 ℃; the elongation increases monotonically and the flat tensile fracture structure is formed under the condition of corrugated and flat rolling, so that the Mg/Al composite plate has good bonding properties; the bending strength increases first and then decreases, and the maximum value occurs at 350 ℃. Compared with the method of flat and flat rolling, the strength of the composite plate by the method of corrugated and flat rolling is higher. It can be seen that the bending resistance of composite plate can be further improved by the corrugated and flat rolling
