Key words: continuous cooling transformation, microstructure, cooling rate, hardness, rotor steel.
Abstract: A diagram of continuous-cooling transformations in rotor steel 30Cr2Ni4Mo (30Kh2N4MF) in the range of cooling rates from 0.01 to 10 Ksec is plotted with the help of a dilatometric method. The changes in the morphology of the products of transformation of austenite and in the Vickers hardness, which occur upon growth in the cooling rate, are studied and analyzed.
