PURPOSE: To produce a composite material having high elongation by pouring molten metal while dispersing under fine particle condition to make semi- solidified state, piling while mixing fine additive having high melting point with this and solidifying to dispersing the additive.

CONSTITUTION: The molten metal of Al, etc., is made to fine particles having ≤1 mm diameter and poured in a mold or on a table and piled under semi- solidified state. While the additives of high melting point particle for dispersed- reinforcing, staple, whiskers, etc., are added and mixed to the molten metal having semi-solidified state by blowing, etc., at the same time, they are piled and solidified. By this method, a metal base composite material having high strength and rigidity and excellent wear resistance and heat resistance is obtd.
