Abstract

METHOD OF PRODUCING HIGH CARBON HARD ALLOYS A method for forming high carbon hard alloys using powdered metal techniques wherein the carbon content of the atomized powdered metal particles is minimized and the carbon content to achieve the desired composition is provided by blending carbon or carbon containing powder with the powdered metal particles prior to compaction and sintering. The compact may be sintered just above the solidus temperature of the alloy.
