The physical metallurgy of iron and steel is exceedingly complicated and many of the complications arise from the behavior of solutes, which segregate to surfaces and interfaces, which alter the mechanical behavior. The modified Darken model was used to describe the complex segregation behavior of the species involved. Trends in the surface concentration changes as describe by the Darken model for a ternary alloy are shown. Simulations were done for different interaction parameters, different bulk concentrations of the species, different segregation energies of the species and different mobilities (diffusion coefficient and activation energy).
