The effect of equal-channel angular pressing on the structure and mechanical properties of sintered Al–Sn composites with a different content of the second phase is investigated. It is established that the pressing results in a hard strengthening of the composite owing to grain structure refinement in the aluminum matrix. The strength of the processed composites is determined from the mixture rule. The shape of tin inclusions almost returns to the original one after each even number of equal-channel angular pressing by route C, while their thickness decreases with the number of pressing passes by route A. A decrease in the interlayer thickness leads to the additional refinement of grains in the aluminum matrix and causes the additional strengthening of Al–Sn composites.
