摘要： The present invention relates to a method for manufacturing a sintered ferromolybdenum alloy, in which a mixed powder of a mill scale (a mixture of Fe, FeO and Fe2O3) as a ferrous raw material discharged from a hot rolling and forging process of the steel-making process and a molybdenum oxide powder as a molybdenum raw material is primarily reduced with a hydrogen gas at low temperature, and then is secondarily reduced with the hydrogen gas at high temperature and simultaneously is cooled in a hydrogen atmosphere to thereby obtain a ferromolybdenum alloy in the form of a powder, and subsequently the obtained ferromolybdenum alloy powder is mixed with wax (Kenolube P11) and the wax-containing mixture is compacted or pressure-molded, after which the molded product is heat-treated in a hydrogen gas atmosphere and then is cooled, thereby manufacturing a sintered ferromolybdenum alloy, and a sintered product manufactured by said method.

摘要： This chemical vapor synthesis process was designed so that a metal carbide precursor and a secondary metal precursor are separately or together fed into each evaporator in a reactor by specially designed precursor feeders, either simultaneously or sequentially. The reduction and carburization of the vaporized precursors by gaseous mixtures produces carbide-metal nanocomposite powders. The product can be a very uniform mixture of the constituent powders or a uniform agglomerate, which is important to ensure a high quality of bulk cemented metal carbide product after consolidation and sintering. These nanocomposite powders can be readily characterized using XRD, carbon analyzer and TEM.
