摘要： A process for the powder-metallurgical production of a workpiece by filling a binder-free and solvent-free, dry metal powder or ceramic powder into a mold, precompacting the powder by tapping and presintering it for 1/2 hour to 1 hour at 0.65 to 0.85 times the absolute melting temperature without significant shrinkage, adjacent powder particles being joined merely at their contact points by necking to give a skeletal formed body. The formed body is taken out of the mold and finish-sintered at at least 0.9 times the absolute melting temperature for at least 1 hour without additional support by a mold. Advantageously, the sintered body is additionally hot-isostatically pressed containerless in order to reach at least 98% of the theoretical density.

摘要： A method for zone heat treatment of metallic workpiece with a comparatively large cross-section, in which the workpiece is successively passed through a zone of higher temperature in such a way that the temperature of the workpiece initially rises steeply as a function of the displacement in the feed direction, passes through a flat maximum and then falls with a small slope. The method is carried out by passing the workpiece through a heating device equipped with a heating coil and a subsequent insulation body, or alternatively through a furnace. In a special embodiment of the method for obtaining the highest possible temperature gradient, the workpiece is drawn from a water bath and then passed through the heating coil.
