Abstract

To fabricate ultra-fine grain structures containing high strength, accumulative roll bonding is a kind of severe plastic deformation (SPD). In the present study, magnetic Al/ Fe₂O₃ composites reinforced with 0, 2.5% and 5Wt.% of Fe₂O₃ particles have been manufactured via ARB. A uniform distribution of Iron oxide particles was achieved after the 8^th cycles of ARB. Mechanical properties include (hardness, elongation, toughness) and also, magnetic and electrical properties such as magnetic saturation, magnetic permeability and magnetic residuals were studied. The presence of Fe₂O₃ particles improved the mechanical, electrical and magnetic properties of this kind of laminated composites. Vibrating sample magnetometer was utilized to study the magnetic properties of samples vs No. of steps.
