摘要：

The microstructure of a SiC particulate reinforced Al 2080 alloy has been characterized by focussed ion beam microscopy and transmission electron microscopy. A 40 nm thick amorphous interface layer develops during processing of the composite material by diffusion of Al and Mg into the pre-existing SiO2 layer on the 3 mum SiC particles. During tensile deformation, damage occurs in the near-interface zone of the matrix, at the particle-matrix interface and within the SiC particles. (C) 2003 Acta Materialia Inc.
