ABSTRACT:
A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by mixing it with iron and any other desired metalloid and/or elements to form a molten mixture, treating the molten mixture to a separation step to remove insoluble slag formed in said molten mixture, and rapidly cooling the molten mixture to below its vitrification temperature to form a solid amorphous metal alloy.
