Multicomponent phase selection theory applied to high nitrogen and high manganese stainless steels

Phase selection theory enables a prediction to be made as to which phase forms first when a molten alloy is solidified. Here it is applied to a multicomponent system to provide information about the δ–γ transition that may occur in high nitrogen and high manganese steels. The theoretical predictions are compared with experimental results for microstructures obtained by means of copper mould casting.
