The main purpose of this study was the description of phase transformation kinetics during continuous heating from the as-quenched state (tempering) of newly designed tool steels for mill rolls with different carbon content. Dilatometry was used to determine the characterictic temperatures of phase transformations occurring in the investigated steels during he4ating from the as-quenched condition. The paper contains interpretations of dilatometric curves and describes the influence of heating rate on the temperature range of occurrence of a particular transformationż The effect of carbon content on transformation strains was also studied.

Celem niniejszej pracy był opis kinetyki przemian fazowych przy nagrzewaniu ciągłym ze stanu zahartowanego (odpuszczaniu) nowo zaprojektowanych stali narzędziowych na walce hutnicze o różnej zawartości węgla. Na podstawie badań dylatometrycznych wyznaczono zakresy występowania poszczególnych przemian fazowych podczas nagrzewania ze stanu zahartowanego. Zamieszczono interpretacje dylatogramów oraz opisano wpływ szybkości nagrzewania do odpuszczania na temperaturowe zakresy wystepowania poszczególnych przemian. Ponadto opisano wpływ zawartości węgla na efekty dylatacyjne towarzyszące poszczególnym przemianom.
