“…Even after cold rolling to 75% reduction, cracks could be seen at only a few interfaces, where particles formed clusters. This is unlike the situation seen in many other interfaces like A1/A12 0 3 (Ruedl 1969) and Cu/SiO 2 and Cu/AI203 (Humphreys and Stewart 1972). The regions around the interface are highly misoriented with respect to surrounding regions resulting in local lattice rotation as shown in figure 15 (Fine et a!…”

The fundamental and engineering aspects pertaining to the matrix-reinforcement interfaces in discontinuously reinforced metal matrix composites are presented in this overview. The interfaces play a key role in determining mechanical properties, namely Young's modulus, yield strength, elongation, creep and fracture behaviour, as well as physical properties like coefficient of thermal expansion, thermal conductivity and damping characteristics of metal matrix composites; these are discussed in detail. The ratio of the experimental value of the Young's modulus to that predicted from the rule of mixtures has been used as a measure of interracial bond strength. Various issues such as the nature of the interfacial bond, chemical reaction at the interfaces, and effect of alloying and processing on the structure of the interfaces and the properties of the composite are examined. In order to exploit the full potential of reinforcing the metallic matrix, the suggested strategies include creation of metallic bonding at the interface, use of in situ processing, choice of right type of alloying elements, and heat treatments and engineering of interfaces.
