Many researchers have studied the microstructure and mechanical properties of Al/Mg composites rolled at a unique temperature; however, the effect of rolling temperature, which is one of the more decisive accumulative roll bonding (ARB) parameters, has not been investigated. In this work, laminated Al/Mg composites were fabricated by ARB at different temperatures using AZ31 magnesium alloy and commercially pure aluminum sheets. The microstructure of the layers and the mechanical properties of the rolled Al/AZ31 composites were investigated. Tensile and bending properties of the multilayer materials were examined by tensile and three-point bending tests. The results showed that mechanical bonding of the layers was improved with increasing rolling temperature. As a result, the intermediate rolling temperature (300 °C) indicated the best mechanical properties. Moreover, hot rolling caused an accelerated formation of intermetallic compounds.
