Особенности кинетики распада и структурообразования в хромомолибденованадиевой стали при непрерывном охлаждении от различных температур аустенитизации

Influence of austenite grain size of chrome-molybdenum-vanadium steel on formation of structure at continuous cooling has been studied. It is shown, that at the coarsen of grain with increasing temperature of austenitization from 850 till 1050 ° С stability of the supercooled austenite in structure of chrome-molybdenum-vanadium steel is increased, that is promoted decrease in critical quenching rate.
