Abstract

A process for producing alloys, particularly iron-base alloys containing magnesium, wherein the alloy constituents are molten under pressure of an inert gas and the melt is rapidly solidified in a chill mold. As a result of this rapid solidificatlon, the magnesium is retained as a fine dispersion or separate phase, allowing a high magnesium recovery rate in the ductlle cast irons or compacted graphite cast irons, treated with said alloys. The apparatus for this process consists of a charge vessel (24) far an alloy charge, means (22) for receiving the molten alloy and for rapid solidification of the alloy and means (66) for supplying inert gas under pressure to the vessel.
