摘 要：<正> Using the calculation of thermodynamicequilibria in multicomponent systems,two ternaryphase diagrams,Ni-Cr-Mo and Ni-Cr-Co,havebeen calculated by optimizing the Gibbs free ener-gies with respect to phase diagrams andthermodynamic data.On the basis of this calcula-tion,the occurrence of σ-phase in the residual solidsolution of commercial Ni-base superalloys,IN-713C and U-700,has been predicted.The re-sults show that the calculation of phase equilibria issuccessful in the prediction of the occurrence of theσ-phase.
