Study of Age Hardening Behavior in a 350 Grade Maraging Steel

  • Chapter
Characterization of Minerals, Metals, and Materials 2015

Abstract

The age hardening behavior in the 480–600 °C temperature range was studied in maraging steel 350. The age hardening at 480, 520, and 560 °C was modeled by an equation derived from the Johnson-Mehl-Avrami-Kolmogorov (JMAK) model, while the overaging stage at 520, 560, and 600 °C was examined using a model based on the Orowan mechanism and on the Pardal model. The results show that the model based on JMAK for the early aging stages has good fitting with the experimental data in the 480–560 °C range. Furthermore, the precipitation seems to occur in two stages at 480 °C. In addition, the model based on the Orowan mechanism and on the Pardal model has good fitting at 520 and 560 °C, but the Pardal model fitting is better than that of Orowan at 600 °C. This behavior is due to the reversion of martensite, which becomes significant when the temperature increases.
