ABSTRACT:
A process for producing ferromolybdenum alloys by agglomerating a finely-particulated mixture containing controlled amounts of molybdenum disulfide and an iron bearing material into a plurality of pellets and heating the pellets to an elevated temperature under a controlled vacuum for a period of time sufficient to effect a dissociation of the molybdenum disulfide and an extraction of the sulfur and other volatile constituents in the pellets and an alloying of the metallic molybdenum produced with the iron bearing material producing substantially dense sintered ferromolybdenum alloy pellets.
