摘要: Abstract A general approach combining experimental measurements of Gibbs energy and phase equilibria, thermodynamic modelling phases calculation diagrams is used to study the ternary Fe–Ni–S system. quasi-subregular model describe properties metal alloy at high temperatures, a statistical for monosulfide phase, an associated solution metal-sulfur liquid disulfide treated as pseudo binary solid solution. Values parameters were obtained using equilibrium data in our own laboratory Wisconsin well those reported literature. Agreement between calculated values are quite good. Using phases, system from down 1173 K. set presented stability diagrams. Phase temperatures l...
