Microstructure Changed during Accumulative Roll Bonding of Al/Mg Composite


Article Preview

In this study, the ARB process is used and the Al(1100)/Mg (AZ31) alloys which is chosen. Steps of 12 layers are created. The ARB process creates a multilayer compound between Al/Mg layers with excellent bonding characteristics and fine grained microstructure. The bonding condition became ascendant gradually with increased from 1 to 3 cycles. The grain sizes of Al and Mg alloys were reached to 875 nm and 656 nm after 3 cycles. The hardness of the Al and Mg alloys were raised to 42Hv and 90Hv after 3 cycles.
