Abstract
The present invention concerns a method of producing powder-metallurgical compacted components, which during subsequent processing are split into individual parts mating in pairs, sintered and optionally heat-treated and remated. According to the process, an iron-based powder is compacted, the obtained green body is fracture-split into at least two parts, which are subsequently sintered and optionally heat-treated. The obtained sintered parts are then remated.
