Abstract
This paper presents the results of a study of the decay of the Fe3C phase during thermal cycling near the temperature of the phase transition of the second kind, which is 210 C (Curie point of cementite). As a result of the conducted studies, it was found that structurally free tertiary cementite, present in low-carbon steels, is primarily susceptible to decay. In preeutectoid and eutectoid steels, cementite as an independent phase may be present in the composition of granular perlite. It was revealed that in the structure of steel U10 with the initial state of granular perlite, the maximum volume fraction (about 0,8).
