Influence of Deep Cryogenic Treatment on Martensite and Carbides Morphology of H11 Tool Steel

Popis výsledku v původním jazyce

Unlike conventional cold treatment, which is commonly used for elimination of retained austenite, deep cryogenic treatment (DCT) primarily improves the wear resistance of tools. This effect is supposed to result from preferential precipitation of fine carbides during annealing which follows after deep freezing. The formation mechanism of these carbides is the subject of several recent investigations performed mainly on high speed steels. The article describes the influence of DCT on the microstructure and properties of X37CrMoV5-1 (H11) hot working tool steel. The result show a significant improvement of wear resistance through DCT, especially at high sliding velocities that are typical of many industrial applications of hot working steels (e.g. closeddie forging). Apart from this, some effects of DCT on the microstructure were found, which contributed to better understanding of this process.
