Application of annealing and accumulative roll-bonding processes forenhanced mechanical properties of Al 1050

In this study, mechanical properties of bulk ultrafine-grained materials (Al 1050 alloy) produced by severe plastic deformation modified or enhanced by a mild annealing treatment. In order to put the UFG materials for structural use, they must have bulky dimensions. This method is based on Accumulative roll bonding (ARB) and appropriate annealing treatments. The ARB process up to 8 cycles was performed at ambient temperature under unlubricated conditions. Then annealing at 275ºC for 90 minute applied. Here, how annealing treatment affect the mechanical properties discussed.
