By increasing the temperature at which low-pressure carburizing is performed, the process time for production of case-hardened steels decrease but run a risk of abnormal grain growth occurring during carburizing. Particles present in the steel pin the grain boundaries and can prevent this growth depending on their size and volume fraction. In this report, the grain growth and particle stability in specifically aluminium nitride containing steels are investigated through thermodynamic calculations, precipitation simulations, and mock carburizing in atmospheric- and low pressures. The results show that no or minimal grain growth occurs at lower temperatures and for steels with a higher pinning force from the particles, and that abnormal grain...
