Abstract
PURPOSE: To easily manufacture a grain reinforced composite material contg. the reinforcing material mixed uniformly with the matrix metal by mixing a powdered metal with a powdered reinforcing material, press-molding the mixture into a billet, and extruding the billet after heating to a specified temp.
CONSTITUTION: A molten Al alloy M for a matrix material is poured in a crucible 1, cooled to a semimolten state contg. about 20% solid phase, slowly granulated by agitation with an agitator 2, and wholly powdered by continuous agitation. To the powdered Al alloy is added a necessary amount of alumina powder P as a reinforcing element, and they are uniformly mixed by agitation. This mixture is put in a metallic mold 6 and molded into a billet 8 by compression with a ram 7. The billet 8 is heated to the melting temp. of the Al alloy in a furnace 9, and when the matrix Al alloy in the billet 8 becomes a semimolten state, the billet 8 is put in an extruder 10 and extruded to manufacture a rodlike product 12 made of grain reinforced composite material contg. the alumina grains dispersed uniformly as the reinforcing material in the matrix.
