The phase recrystallization of medium-carbon steel with the initial structure of lamellar pearlite in the process of short-term heating to different temperatures above Ac

and subsequent cooling has been studied. The structure of steel formed under the nonequilibrium conditions corresponding to the decomposition of supercooled austenite has been described. It has been shown that the changes in the structure and phase composition that arise during this treatment have a noticeable effect on the characteristics of the deformation behavior of the material determined based on the results of dynamic indentation.
