| Abstract |
| A complex multi-layer AA1050/AA5052 aluminum alloy was fabricated by an accumulative roll-bonding (ARB) process. A two-layer stack ARB was performed up to three cycles at ambient temperature without a lubricant according to the conventional procedure. A sound complex multi-layer AA1050/AA5052 aluminum alloy sheet was successfully fabricated by the ARB process. For further enhancement of the mechanical properties, the ARB-processed complex aluminum alloy sheets were further rolled to about 50% reduction by conventional rolling with the same rolling machine, which resulted in a thickness of just 1 mm. The mechanical properties of the ARBprocessed materials were investigated in detail and compared to the results of previous studies. |
