Aluminium-based Metal matrix composites (MMCs) have become increasingly used for structural applications in various industrial sectors because of their excellent specific stiffness and specific strength. Discontinuously reinforced (DR) Al/SiC metal-matrix composites (MMCs) are modern, lightweight materials which have a very attractive combination of material properties and price. The use of DR Al/SiC MMCs is mostly limited to the military and aerospace, however, these materials are now beginning to penetrate civilian applications. Besides the mechanical behavior, knowledge of the corrosion resistance of DR Al/SiC MMCs is very important, and so the corrosion resistance of Al/SiC composites has been investigated and discussed in comparison with a conventional Al alloy of similar composition.

The infiltration process is one of the techniques employed to work out polymer matrix composites (PMC) or metal matrix composites (MMC) and with continuous reinforcement. It consists in injecting the liquid (resin or metal) through a fibrous reinforcement placed in a mould. In the case of the MMC, the fibres and the mould are initially preheated at temperatures lower than the temperature of metal solidification. These thermal conditions induce phenomena of phase change of metal when the metal is in contact with the fibres. These phenomena disturb the flow of metal through the fibrous network. In order to follow the displacement of metal in the preform and take into account of the phase change, a two-dimensional numerical model based on a finite volume formulation was developed, on a very simple geometry.

As part of a broad program on composite materials, the role of the interface on the micromechanics of deformation of metal-matrix composites is being studied. The approach is to correlate elastic behavior, micro and macroyielding, flow, and fracture behavior with associated structural detail (dislocation substructure, fracture characteristics) and stress-state. This provides an understanding of the mode of deformation from an atomistic viewpoint; a critical evaluation can then be made of existing models of composite behavior based on continuum mechanics. This paper covers the electron microscopy (transmission, fractography, scanning microscopy) of two distinct forms of composite material: conventional fiber-reinforced (aluminum-stainless steel) and directionally solidified eutectic alloys (aluminum-copper). In the former, the interface is in the form of a compound and/or solid solution whereas in directionally solidified alloys, the interface consists of a precise crystallographic boundary between the two constituents of the eutectic.
