| Zusammenfassung: | A method of manufacturing a sized powder metal component having improved fatigue strength. The method includes the sequential steps of solutionizing a sintered powder metal component and quenching the sintered powder metal component, sizing the sintered powder metal component to form a sized powder metal component, re-solutionizing the sized powder metal component, and ageing the sized powder metal component. The sized powder metal component made by this method, in which the component is re-solutionized between sizing before ageing, can exhibit exceptional improvements in fatigue strength compared to components prepared similarly but that are not re-solutionized. |
