The investigations were performed by means of the dilatometric method on two model alloys of almost similar chemical compositions but of differentiated concentration of vanadium (0.14 and 0.77%). The samples of each alloy were austenitized at the temperatures, when almost all vanadium carbides of MC type remained undissolved, and at the temperatures of dissolving of MC carbides when entire vanadium passed into austenite. It was observed that vanadium bound into MC carbides affects weakly the kinetics of transformations of the undercooled austenite and its influence is much stronger when it is completely dissolved in the solution (austenite).
