摘　　要：提出一种采用衬板轧制进行AA1060铝/AZ31B镁/AA1060铝复合板的制备方法。结果表明:传统轧制铝/镁/铝复合板截面轮廓较为平直,而衬板轧制由于衬板可将剪切力部分转化为压应力,从而改变复合板板受力状态,在铝/镁界面连接处形成差速流动,故而界面轮廓呈现波浪状特征,层间实现互锁连接。界面连接强度为64 MPa,是传统轧制复合板的4倍。力学性能测试表明:衬板轧制复合板的抗拉强度可达210 MPa,比传统轧制法提高12.3%。综上可知,衬板轧制法为高性能铝/镁/铝异质复合板成形制造提供一种新思路。A hard plate rolling(HPR)method was proposed to develop the AA1060 Al/AZ31B Mg/AA1060 Al composite plate.The results show that the interface of the traditional Al/Mg/Al composite plate is relatively flat.The hard plate rolling can change the stress state of the composite plate by converting the shear force into compressive stress,and form a differential flow at the Al/Mg interface connection.Consequently,the interface profile becomes corrugated,and the interlaced bond between the layers is achieved.The interfacial bonding strength is 64 MPa,which is four times that of traditionally rolled composite plate.The tensile strength of hard-rolled composite plate can be as high as 210 MPa,which is 12.3%higher than that of the traditional rolling method.In conclusion,the hard plate rolling process provides a new idea for the research of forming and manufacturing high-performance Al/Mg/Al heterogeneous composite plates.
