Resumen

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 8th 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. © (2023). All Rights Reserved.
