| Abstract | ||||
| Accumulative Roll Bonding (ARB) is a prospective severe plastic deformation (SPD) process that can continuously produce bulk material and has good commercialization potential. This paper aims to study the effect of different ARB cycles in details on tensile strength, elongation, and strain-hardening coefficient. Aluminum sheets AA1050 were heated at 300⁰C, then rolled for a single pass with 67% reduction in thickness and air cooled. The produced sheet was cut and accumulative roll bonded (50% reduction) after reheating at 280⁰C with different ARB cycle regimes. The tensile testing was carried out at room temperature after different cycles of ARB. Ultimate tensile strength, elongation, and strain-hardening coefficient were determined. The results indicated that UTS after ARB is significantly improved by accumulative roll bonding achieving 121% of AA1050. This improvement is attributed to the reduction of grain size and increasing the grain boundaries. However, the total elongation percentage were reduced, at which the elongation reduced by a factor 95% of AA1050." | ||||
