Abstract

Abstract

In the process of particulate reinforced metal matrix composites the injection of the solid particulate into the molten metal is computed in this paper.By considering the resistance for the injection of a particulate as comprising drag,surface force and buoyancy,a criterion has been derived.For the implant of a particulate there is a minimum impinging velocity of a particulate onto the melt.Larger diameters of particulates,improvement in the wetting condition,and an increase of kinetic energy of particulates will favor the initiation of particulate transfer to melt.
