Abstract
A process and apparatus are disclosed for the production of a solid metallic composition such as ferromagnesium wherein one constituent has a melting point which is above the boiling point of the second constituent. In accordance with the disclosed process, a liquid melt of the first constituent is formed which has an effective depth sufficient to produce a static pressure head in excess of the vapor pressure of the second constituent at the temperature of the melt. The second constituent is then melted and mixed with the first constituent to form a liquid mixture wherein at least a portion of the second constituent is in solution with the first constituent. The mixture is then solidified rapidly to form a solid metallic composition in which a substantial part of the second constituent appears as a dispersion of fine particles of the second constituent in a matrix of the first constituent. The apparatus includes a columnar furnace communicating with a reaction chamber to provide the requisite pressure within the reaction chamber, an adder mechanism to supply the low-boiling point constituent to the pressurized reaction chamber and means to cool and solidify the liquid mixture rapidly so as to form the desired dispersion of fine particles of the low-boiling point constituent in a matrix of the other constituents.
