ABSTRACT:
A composite material is produced by placing a plurality of blocks of cast iron having high wear-resisting properties on the bottom of a mold, pouring into the mold a molten impact-resisting cast steel, allowing the molten steel to solidify and subjecting the solidified mold to a heat treatment. The composite material thus produced can exhibit both excellent wear- and impact-resisting properties.
