Effects of the initial structural state and of the rate of subsequent heating on inheritance of structure in steel 718 are studied. Metallographic analysis of the steel after various modes of heat treatment is performed. The critical temperatures of the steel are determined. Heating curves are plotted for specimens in different initial states with the help of a DIL-805A dilatometer. Recommendations are given on lowering the inheritance of structure in large-section preforms from steel 718.
