Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

MODELING AND FABRICATION OF Al/Al2O3 COMPOSITES USING ACCUMULATIVE ROLL BONDING PLASMA ELECTROLYTIC OXIDATION

Although the current field of application Al–alloy 7075 (AA7075) is vast, it still limited due to some drawbacks, especially its susceptibility stress corrosion cracking (SCC). This work aims evaluate microstructural, mechanical, and (SCC) behaviors on an AA7075 in flat format deformed by a combination repetitive corrugation straightening (RCS) accumulative roll bonding (ARB) techniques. Four d...

Ultrafine-grained Cu/Al/Ag composites were processed by an accumulative roll bonding (ARB) technique from pure copper and aluminum sheets a silver powder. The Al content was fixed to 11 wt.% while the concentration 1, 2, or 3 in wt.%. ARB-processed samples heat treated at different temperatures between 750 1050 °C for 60 min then quenched room temperature (RT) producing Cu–Al–Ag alloys. effect ...

This paper aims to investigate the properties of aluminum-based composite Al2O3/SiC ceramics using new severe plastic deformation (SPD) methods and finite element method. research work also focused on accuracy simulation results in manufacturing reinforced ceramic. The latest method was developed by repetitive press-roll forming (RPRF) for processing ceramic-reinforced materials. simulations we...

Accumulative Roll-Bonding (ARB) is one of the more recently developed techniques capable of producing bulk ultra-fine grained (ufg) metals. There are still many aspects of the behavior of ufg metals that lacks an in-depth understanding, such as a generalized view of the factors that govern the cyclic deformation mechanism(s). This study aims to advance the understanding of the cyclic deformatio...
