• During annealing of steels different kinds of enrichments are observed on steel surfaces. Equilibrium segregation of a dissolved element leads to enrichment in the range of a monolayer, two interacting elements can form two-dimensional compounds by cosegregation and also chemisorption induced segregation leads to monolayer surface compounds. If the concentrations or pressures are exceeded which are necessary for the formation of three-dimensional bulk compounds, enrichments occur due to surface precipitation resp. oxidation. On the other hand, oxidation can cause segregation or accumulations of dissolved elements beneath the oxide scale.<Br>These different phenomena are fundamentally discussed and examples are presented, which are important in the steel production and for the steel properties.
