Abstract
Purpose: This work contains a detailed description of the kinetics of phase transformations during continuous heating from quenched state of HS18-0-1 and HS6-5-2 high-speed steels. Design/methodology/approach: The kinetics of phase transformations during continuous heating (tempering) from as-quenched state of investigated steel, was elaborated using a DT 1000 dilatometer of a French company Adamel. Findings: During heating of previously quenched HS18-0-1 and HS6-5-2 steel samples, the presence of four basic transformations was found, i.e. precipitation of epsilon carbide, precipitation of M3C, transformation of retained austenite and precipitation of alloy carbides of MC and M2C type. It was shown that in quenched high-speed steels a part of retained austenite transforms already during heating for tempering, but its significant part transforms only during cooling process after tempering. Research limitations/implications: The substitution of tungsten with molybdenum in HS6-5-2 steel has influenced mainly the stability of retained austenite and the temperature of precipitation beginning of MC (MCS) type carbides. Practical implications: This results will be used to design new technologies of tempering of these steels. Originality/value: Characterization of kinetics phase transformations during continuous heating from quenched state in high-speed steels.
