The results obtained from the Vienna Ab Initio Simulation Package (VASP) were compared with the data from high temperature carburization and high temperature oxidation experiments. The samples were characterized using optical microscopy, scanning electron microscopy, focused ion beam microscopy, energy dispersive X-ray spectroscopy, and other techniques. Despite limitations of system size of the VASP, it is able to efficiently predict the diffusion behavior of interstitial elements in well-ordered materials.
