Abstract (en)
The object of the invention is an easily sinterable prealloyed iron-based powder and the method for its manufacturing. The easily sinterable prealloyed iron-based powder comprises according to the invention at least 80% Fe by weight, Cu and P as alloying additives and inevitable impurities, particularly hardly reducible oxides. A method for producing the easily sinterable prealloyed iron-based powders according to the invention comprises the successive steps: preparing a reducible material; subjecting the said reducible material to mechanical processing by milling, including grinding, homogenization and activation of the reducible material; annealing the said ground homogenized and activated by milling reducible material in a reducing atmosphere; cooling the said reduced material to a temperature preventing its self-ignition; and grinding the said cooled material to a powder having a predetermined average particle size. The invention further relates to the use of the easily sinterable prealloyed iron-based powder for the production of sintered structural and tool components, in particular sintered metal-diamond composites, and the sintered product, especially the sintered metal-diamond composite, wherein the total porosity of the sintered product at a temperature not higher than 950°C is lower than 5%.
