Effect of plastic deformation of austenitizing temperature was investigated on phase transformations, structure and hardness of the supercooled austenite transformation products of the Cr-Mo constructional steel with Nb, Ti, and B microadditions. Basing on the analysis of the phase transformation plots of the supercooled undeformed austenite and of the supercooled and plastically deformed one, it was found out that direct cooling of specimens after completing their plastic deformation in the abovementioned conditions, results in a significant acceleration of the alpha -> beta, and ferritic and pearlitic transformations, and in the decrease of the transformation products hardness. These phenomena are of great importance for working out of the thermo-mechanical treatment of products made from the heat-treatable microalloyed steels.
