Role of segregation and precipitates on interfacial strengthening mechanisms in SiC reinforced aluminium alloy when subjected to thermomechanical processing. Journal of Materials Processing Technology, 153, 758-764.Full text not available from this repository.
The satisfactory performance of metal matrix composites depends critically on their integrity, the heart of which is the quality of the matrix-reinforcement interface. The nature of the interface depends in turn on the processing of the metal matrix composite component. At the micro-level the development of local concentration gradients around the reinforcement, as the metal matrix attempts to deform during processing, can be very different to the nominal conditions and play a crucial role in important microstructural events such as segregation and precipitation at the matrix-reinforcement interface. These events dominate the cohesive strength and subsequent mechanical properties of the interface. The compositional variations at the matrix-reinforcement interface of a metal matrix composite are reported, emphasising the interfacial strengthening mechanisms during thermomechanical processing. A method of calculation has been applied to predict the interfacial fracture strength of aluminium and SiC interface, in the presence of magnesium segregation. (C) 2004 Elsevier B.V.
