Abstract
A iron-based material such as cast iron is made by a process wherein filler particles are added to an iron base metal, as the base metal is poured into the mold. Pieces containing ceramic filler particles held together by a binder can be disposed in the mold prior to pouring molten iron base metal therein. Molten iron base metal is then poured into the mold so that the molten base metal contacts the pieces, gradually dissolving the filler. The filler becomes distributed throughout the molten base metal within the mold. Upon cooling, the base metal has the filler distributed therein, resulting in a iron-based material. The resulting material is particularly useful for making vehicle parts normally made of cast iron or steel.
