Note: Precipitation of MX Carbides/Nitrides in steel MX carbides (M = V,Nb, X = C,N) are known to have a positive effect on the grain size in ferritic or dual phase steels. This effect comes from pinning of grain boundaries and thereby slowing down grain coarsening during austenitization on the one hand. On the other hand carbides/nitrides may act as nucleation sites for ferrite during cooling and thereby promote fine ferritic grains. The project shall investigate the stability of precipitates during austenitization by different simulation approaches (Thermocalc, Phas-field) and discuss the potency of MX carbides/nitrides for ferrite nucleation.
