Corrosion Behavior of Al-2wt%Cu Alloy Processed By Accumulative Roll Bonding (ARB) Process
Accumulative roll bonding (ARB) imposes severe plastic strain on materials without changing the specimen dimensions. ARB process is mostly appropriate for practical applications because it can be performed readily by the conventional rolling process. An Al-2wt%Cu alloy was subjected to ARB process up to a strain of 4.8. Stacking of materials and conventional roll-bonding are repeated in the pro...
متن کاملDevelopment of interface-dominant bulk Cu/V nanolamellar composites by cross accumulative roll bonding
Traditional nanostructured metals are inherently comprised of a high density of high-energy interfaces that make this class of materials not stable in extreme conditions. Therefore, high performance bulk nanostructured metals containing stable interfaces are highly desirable for extreme environments applications. Here, we reported an attractive bulk Cu/V nanolamellar composite that was successf...
متن کاملComputational evaluation of the homogeneity of composites processed by accumulative roll bonding (ARB)
A new computational method based on MATLAB was used to study the effect of different parameters on the homogeneity of composites produced by a severe plastic deformation technique known as accumulative roll bonding. For a higher number of passes, the degree of particle agglomeration and clustering decreased, and an appreciable homogeneity was obtained in both longitudinal and transverse directi...
متن کاملAnnealing Effects in Twin-Roll Cast AA8006 Aluminium Sheets Processed by Accumulative Roll-Bonding
Ultrafine grained sheets were prepared from a twin-roll cast AA8006 aluminium alloy using accumulative roll-bonding process at room temperature. The evolution of microstructure of sheets after three accumulative roll-bonding passes during isochronal annealing with a constant step of 20 °C/20 min was studied by light and electron microscopy. The influence of the resulting microstructure on mecha...
متن کاملFormation of a solid solution through accumulative roll bonding (ARB) and post-heat treatment of multilayered Cu/Zn/Al
In the present study, the capability of accumulative roll bonding (ARB) and subsequent heat-treatment to fabricate solid solution from a multilayered Cu/Zn/Al was investigated. Two post-heat treatment (one-step and two-step) routes were proposed. In the first, the ARB processed material was heated to 800 C for 5:30 hours and allowed to cool slowly in a furnace (one-step route). In the second (t...
