摘要： A steel powder composition useful in the production, by powder-metallurgical methods, of sintered parts with high density, good dimensional accuracy, hardenability, and strength is prepared from an admixture of two pre-alloyed iron powders of different compositions, the first being a pre-alloy of iron and molybdenum, and the second being a pre-alloy of iron with carbon and at least one transition element including chromium, manganese, vanadium, or columbium.

摘要： An improved powder composition of an iron-based powder and an alloying powder is provided. Segregation and dusting of the alloying powder is eliminated or substantially reduced when the powder composition contains a polymeric binding agent which is an adherent film-former and which is insoluble in water.
