A magnetic method for determining the concentration of residual austenite in maraging steels
Source abstract
Abstract
The results of measurements of magnetic properties of maraging steel 08Kh15N5D2T subjected to different types of thermal treatment, namely annealing, hardening, and aging, are presented. The required concentration of residual austenite during specimen preparation was obtained by varying the temperature of thermal treatment, the time of exposure, and the heating rate in the case of annealing. The new magnetic parameter N *, which linearly correlates with the concentration of residual austenite, is proposed. An algorithm for previously developed equipment and software, which is intended for the determination of this parameter, is offered.
