Abstract
Purpose: In this paper the effect of carbon content on the transformations taking place at the early stage of tempering (precipitation of the ε carbide) of the model alloys with manganese and vanadium addition is evaluated. Design/methodology/approach: The alloys with specially designed chemical composition (constant content of alloying elements and varied carbon content) were investigated by means of dilatometric method. The range of temperature of the early stage tempering was established on the basis of differentiated dilatogram curves digitally recorded during heating up step of the previously hardened specimens. In order to unify the experimental conditions, only one heating rate was chosen. Findings: It was shown that carbon has a similar influence on the first stage of the tempering of the model alloys containing manganese and vanadium addition when considering a qualitative way of the effect. But when a quantitative way is taken into account, the effect of carbon content is different. Research limitations/implications: Investigations of the early stage of the tempering will be continued for its more accurate quantitative analysis. Authors are expecting that there is a relationship between an intensity of this stage of tempering and steel’s properties. Practical implications: The results of the research have strong cognitive meaning. It is possible that in the future they may be used for designing of chemical composition of steels for which presently only the low-temperature tempering is provided. Originality/value: The results contained in this paper have very high cognitive significance and in the future it may be possible to use them for elaboration of detailed heat treatment technology of new steels, which are anticipated to be subjected to low-temperature tempering only.
