摘要: Temporary cooling of metals under the conditions uniaxial tension and stationary creep is shown to lead formation dislocation loops at subgrain boundaries. The support impeding dislocations in sub-boundaries increase resistance metal. Electron microscopy study has that are prismatic interstitial type. regularities discussed. Es wird gezeigt, das die zeitweise Abkuhlung von Metallen unter den Bedingungen einer uniaxialen Spannung und stationaren Kriechens zur Bildung Versetzungsschleifen an Subkorngrenzen fuhrt. Die Schleifen unterstutzen Festsetzen Versetzungen erhohen Kriechwiderstand des Metalls. Elektronenmikroskopische Untersuchungen zeigten, prismatisch vom Zwischengittertyp sind. Einzelheiten Kriechwiderstandes werden diskutiert.
