Abstract Phase stability diagrams of quaternary hot corrosion type could be constructed on the basis of calculations of ternary mixed environment type diagrams. For both systems the condensed phases were considered to be the reaction products of the metal with two components in the gas phases, while for the hot corrosion type a condensed phase of the Na-O-S system was regarded as the reactant. The equilibrium lines and the triple points in the phase stability diagrams were calculated and selected by the free energy changes associated with the assumed reactions.
