“…As a corollary, the second phase has to contribute significantly to the strength of the composite. Many types of fibre or particulate have been tested for reinforcing an Al-matrix in view of packaging applications: SiC [3][4][5][6][7], Al 2 O 3 [8,9], diamond [10][11][12], graphite flakes [13], fly ash [14], and carbon nanotubes [15,16]. The composites can be processed by squeeze casting or by powder metallurgy provided to control properly the phenomena governing wetting and interfacial reactions with Al.…”
