      abstract     = {In this study, the powder metallurgy method was used to
                      prepare nano-C and in situ Al2O3 hybrid reinforced Al matrix
                      composites, the grain size was refined, and the dispersion
                      of reinforcements was improved by equal-channel angular
                      pressing (ECAP). Twin Si and slip steps were present in the
                      composites reinforced by $0.75\%$ carbon nanotubes (CNTs),
                      $0.25\%$ graphene nanoplatelets (GNPs), and Al2O3 by three
                      ECAP passes. The interface between the CNTs and the matrix
                      was closely bonded. The γ-Al2O3 particles and fibres were
                      generated by an in situ method, and the nucleation and
                      interfacial orientation of Al2O3 were discussed. With the
                      increase in ECAP passes, the electrical and mechanical
                      properties of the composites were improved. The electrical
                      resistivity of the composites reinforced with $0.5\%$ GNPs
                      after three ECAP passes showed the lowest value of 3.64 ×
                      10−8 Ωm. The maximum hardness of the composites
                      reinforced with $1.0\%$ CNTs after three ECAP passes was
                      321.9 HV. The compressive strengths of the composites
                      improved. The strengthening mechanism of the ECAP-treated Al
                      matrix composites was summarised as dislocation
                      strengthening, dispersion strengthening, grain boundary
                      strengthening, and load transfer.},
