ABSTRACT:
An apparatus for making metal-matrix composite includes a feeding container filled with a suspension liquid in the suspending an ultrafine reinforcing material having a particle size as fine as 0.05 .mu.m in a suspension liquid in the container, a refining furnace filled with a molten metal alloy matrix in the refining furnace with the suspension liquid of the ultrafine reinforcing material homogeneously dispersed in the metal alloy matrix for producing a metal-matrix composite by a refining process, which is degassed by inserting a degassing pipe in the furnace to remove gases to eliminate porosity in the composite, thereby producing a metal-matrix composite having improved mechanical properties.
