The Influence of Deformation Modes on the Structure and Properties of Al–Mg–X Powder Composites. I. The Influence of Rolling Conditions on the Mechanical Properties of Aluminum Powder Ribbons Strengthened with SiC Nanoparticles

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