摘要：

In this study, the Accumulative Roll Bonding (ARB) process was used with a snap-stack procedure to reduplicate an Al (1100)/Mg (AZ31) alloy. Samples underwent four rolling and stacking cycles four times, which produced a 24-layer structure. The ARB process creates a multilayer compound between Al/Mg layers with excellent bonding characteristics. The excellent bonding characteristics were due to atomic diffusion. Diffusion couples between Al and Mg were investigated to study the composition of the formation in the Al-Mg system. Layers of intermetallic compound (IMC) Al(3)Mgz and A(12)ZMg(17) were observed. The composition-depth curves of the diffusion zone were determined by electron microprobe analyses of the IMCs.
