Carbide Formation and Decomposition During LPC and Gas Carburizing
During carburizing—especially low-pressure carburizing (LPC)—alloy steels containing carbide forming elements may form carbides. If not properly controlled, these carbides can negatively affect surface carbon levels, hardness, and fatigue performance.
In high-alloy steels, carbide formation during LPC boost steps is often unavoidable. These carbides can supply additional carbon during subsequent diffuse steps. This extra carbon as well as the coarsening rate, carbide formation, and decomposition rate directly influences:
The DANTE Nitriding Model simulates nitrogen diffusion and the nitride phase evolution.
The model accounts for:
Because nitriding induces volumetric expansion and phase transformation strains, these effects must be included for accurate residual stress and distortion prediction.
