This animation shows the in-situ von Mises stress and austenite volume fraction of a bevel gear during a gas carburization and oil quench simulation. It’s always interesting to see how the part moves because of thermal strain and phase transformations. Since the surface of the gear was carburized, the martensite phase transformation is delayed with respect to the core, and some retained austenite exists in the carburized case directly after quenching.
