Abstract
A preliminary mathematical model has been devised for the heat flow during processing of metal-matrix composites by infiltration of fibre preforms with liquid metal under pressure of a punch at a constant velocity. The model addresses microscale heat exchange between metal and individual fibres as well as the macroscopic thermal effects in the billet and mould during the infiltration and casting processes. The detailed physical model and numerical algorithm are provided. The thermal predictions of the model are shown to agree with the experimental measurements and relate well to solidification patterns.
