Abstract

Equal channel angular pressing (ECAP) is one the most important severe plastic deformation techniques with many privileges such as extensive grain refinement. In the present study, the ECAP process of AA6061 is simulated using ABAQUS software and the strain distribution is evaluated. The microstructure of the pressed sample after annealing is predicted and the average grain size is calculated using Monte Carlo algorithm with the aid of MATLAB software. The results indicate that as the strain inhomogeneity increases, the grain structure uniformity after annealing treatment reduces. Moreover, as the channel intersection angle increases, the average grain size is enhanced.
