摘　　要：以Mg-Cu-Al合金作为中间夹层材料，研究了热轧法制备不锈钢／碳钢复合板的工艺，探讨了不同的实验轧制温度、轧制速度、中间夹层厚度、变形量以及二次轧制参数对其显微组织的影响，并对铝合金中间夹层两侧的扩散层的厚度、显微硬度及组织进行了测定，对复合板的拉伸及剪切性能进行了测试．实验结果表明，在首次轧制温度600℃-635℃，轧制速度8～24mm／min，中间夹层厚度0．6～0．9min，变形量14％～28％，二次轧制温度660℃-680℃，轧制速度16～24mm／min，变形量21％～35％工艺条件下，复合板碳钢侧扩散层厚度可达61μm，不锈钢侧扩散层厚度可达50μm，显微硬度达到HV0.025 1000；扩散层主要由Fe2Al5相组成；复合板的抗拉强度达到526MPa，剪切强度达到85NPa．Using Mg-Cu-Al alloy as interlayer material, a stainless steel clad carbon steel plate is prepared by hot-wiling. Effects of rolling temperature, speed, interlayer thickness, deformation and the second rolling parameters on microscopic structure are studied, the thickness of diffusion layer and microhardness are measured, and tensile and shear properties of the clad plate are tested. Experimental results show that within the preparation parameters, a 61μm thickness of diffusion layer is obtained on carbon steel side, and 50μm is achieved on stainless steel side, which have a microhardness over HV0.025 1 000 and consist of primary Fe2Al5 phase. The tensile strength and shear strength reach 526 MPa and 85 MPa respectively.
