Einsatzhärten: Untersuchungen zur Änderung der Härteannahme nach isothermischer Umwandlung

Case hardening: Investigations on the change in hardenability after isothermal transformation To increase economic efficiency of case hardening processes great efforts are made in raising carburising temperature. One possibility to remove the coarse grain appearing after high temperature carburising is to integrate an isothermal transformation into the carburising procedure. Apart from a fine martensitic structure two extra effects appear if this technique is used giving reason to more research work. On the one hand there appears a reduction in hardenability of the investigated material. On the other hand bending strength increases towards conventionally case hardened samples.
