摘要：

The accumulative roll-bonding (ARB) process was applied on the strips of aluminum alloy 1050 in two processing conditions: cold ARB and warm ARB. The results of tensile tests and microhardness measurement show that the warm ARB process exhibits the lower tensile strength and microhardness, more homogeneous distribution of the microhardness, higher elongation, and especially superior planar isotropy of the tensile properties in comparison to the cold ARB, because of the intermediate heat treatment as well as the elevated temperature rolling in the warm ARB process. Furthermore, with increasing the cycles of both processes, the planar isotropy decreases progressively.
