Mechanical characteristics of AL-1050 and Al-6061 alloys deformed using equal channel angular rolling process

Abstract

One of the effective severe plastic deformations (SPD) techniques is Equal channel angular rolling (ECAR) process which can lead to proper ultra-fine grained (UFG) structures of material, the main objective of this work is to study the improvement in mechanical properties within 1050 and 6061 aluminum alloy sheets. There are more attempts to investigate the microstructure and mechanical properties of strips material, the influence of process parameters such as number of equal channel angular rolling passes, routes (A&C) and annealing temperature after each passes on deformation behavior of 6061 and 1050 Aluminum alloys were investigated experimentally .Results was indicated that for AL-6061 without annealing process at first pass it was the higher stress than the passes after annealing process and also the grains was fine in the first pass ,For AL-1050 it was indicated that with ambient temperature at six pass the mechanical properties was improved and its recorded the higher stress with more passes at six pass for rout C and also the fine grains of microstructure was obtained in the six pass with compared to the material with annealing process which becomes more ductility with more passes.
