Changes of enthalpy at the thermomagnetic analysis of tempered Fe-C alloys

In a given work, experimental approaches are advanced for investigation of magnetic effects at phase transformations in Fe-C interstitial alloys based on the iron. As revealed in our previous investigations, the understanding of processes, which occur in interstitial alloys based on the iron, is characterized by presence of many not clear or disputable moments. Therefore, the further investigations in this field were topical from the point of view of the general theory of phase transformations in alloys. The data obtained by us show that, in the field of the theory of formations of phases of Fe-C alloys as well as in general in the theory of formation of phases of interstitial alloys based on the iron, there is a number of the moments, which require the further studying; first of all, they concern the nature of thermal effects at heating the strengthened alloys of iron and change of enthalpy depending on modes of preliminary processing.
