AbstractAn Al–7%Si casting alloy has been subjected to equal-channel angular pressing up to eight passes by routes A, BA, BC and C. Microstructural and mechanical characterization by tensile testing was performed. No significant differences in tensile strength were found between the processed samples. However, there are strong differences in ductility, which are attributed to the dependence of the fracture propagation path on the processing route due to different geometric redistribution of the eutectic constituent.
