THE INFLUENCE OF DEFORMATION MODES ON THE STRUCTURE AND PROPERTIES OF Al–Mg–Х POWDER COMPOSITES. I. THE INFLUENCE OF ROLLING CONDITIONS ON THE MECHANICAL PROPERTIES OF ALUMINUM POWDER RIBBONS STRENGTHENED WITH SiC NANOPARTICLES

Abstract

The influence of deformation modes on the mechanical properties of metal matrix composites produced from aluminum powder strengthened by SiC nanoparticles has been studied. Symmetric and asymmetric rolling processes at room temperature were used. Rolling as additional deformation processing improves the composite structure by refining the SiC agglomerates, asymmetric rolling being a more effective deformation process. It is shown that this complex strengthening technique allows the strength to be increased twofold without decrease in the elastic and ductile parameters.
