Effect of Accumulative Roll Bonding Process with Inter-CycleHeat Treatment on Microstructure and Microhardness of AA1050 Alloy
Processes with severe plastic deformation (SPD) may be definedas metal forming processes in which ultra-large plastic strain isintroduced into a bulk metal in order to create ultrafine grained(UFG) metals.Accumulative roll bonding (ARB)is a SPD process that may be defined as multisteps rolling process in order to create high strength metals with UFGstructure.In this study,ARB process with inter-cycleannealingis carried out on the commercial purity aluminium (AA1050) sheet up to 13 cycles.The purpose of the present study is investigation of microhardness behavior and micro structural evolution in the ARB processed AA1050 sheet.Micro-Vickers hardness measurement is carried out throughout thickness ofthe ARB processed sheets.In addition,with increasing ARB cycles the grains size is reduced in nanometer level.
