This research developed new nanostructured Al–Fe3O4 composites via accumulative roll bonding (ARB). X-ray diffraction (XRD) analysis and field emission scanning electron microscopy were conducted to examine microstructural characteristics and particle distribution in the nanocomposites. Hardness and tensile strength tests were employed to examine their mechanical propertie...

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensil...

Nanostructured Cu-/Al-laminated composites were processed by accumulative roll-bonding (ARB) technique for four cycles. Microstructural evolutions inside the Cu and Al layers interfacial reactions revealed after annealing at different temperatures. Recovery recrystallization occurred in low temperatures, three kinds of intermetallic compounds formed near interfaces. The mechanical properties th...

A nano/ultra-fine grain Al-0.2wt% Zr alloy was produced by accumulated roll bonding (ARB) processafter 10 cycles. The fraction of high angle grain boundaries increased from 8% to 65.4% during 10passes during ARB process. This alloy was subjected to tensile test at different temperatures (523,573and 623 K) and strain rates (0.1 and 0.01 s-1). The optimum condition of temperature and strain rate ...

A cold roll-bonding (CRB) process is applied to study the effects of stacking number on microstructure and mechanical properties roll-bonded age-treated Al sheets. Commercial AA1050 AA6061 sheets with a thickness 2 mm were stacked alternately each other two four layers, by multi-pass rolling. The then subjected natural aging (T4) artificial (T6) treatments. as showed typical deformation structu...
