      abstract     = {In this study, Al-Si matrix composites reinforced with In
                      situ Al2O3, C nanotubes (CNTs), and graphene nanoplatelets
                      (GNPs) were prepared by ball milling, hot-isostatic pressing
                      (HIP), and subsequent high-pressure torsion (HPT).
                      Microstructures, interfacial bonding, and electrical and
                      mechanical properties of the composites were analysed. In
                      situ Al2O3 particles and whiskers were formed via reaction
                      between Al powder and SiO2 powder. Grains of the composites
                      were significantly refined and reinforcements were well
                      dispersed in the matrix by HPT. A sub-micron equiaxed grain
                      structure with an average grain size of 0.60 μm was
                      obtained. Interface between the CNTs and the matrix was
                      narrow and had no brittle phase. With an increase in the
                      number of HPT cycles, microhardness and electrical
                      conductivity of the composites increased. Strengthening
                      mechanism of the Al matrix composites was mainly fine-grain
                      strengthening. Dislocation accumulation and grain boundary
                      evolution caused by HPT were examined.},
