The work presents the solidification kinetics of a composite suspension with graphite particles dispersed in AlMg10 alloy matrix during its flow along a runner. The temperature field for investigated materials has been determined by measuring the suspension temperature values during flow and solidification in the elongated runner-like mould cavity. The influence of the quantity of ceramic particles on the temperature of the solidification beginning has been shown, and by the same its influence on the supercooling of the flowing composite suspension. Differences between the supercooling values for matrix alloy and for composites have been revealed. The obtained results have been interpreted pointing to the influence of graphite particles on activating the nucleation and change of the heat exchange conditions between the flowing suspension and the mould wall.
