摘要：

An optimization method was established to predict phase compositions and amounts in two-phase nickel base superalloys. Based on the compositions of alloys and their gamma' phase, gamma phase compositions and gamma' phase amounts were calculated with the use of the layered multi objective optimization algorithmic approach with tolerance. The optimization process was realized by establishing two relating objective functions and the corresponding constrained conditions. The results verified the feasibility and the accuracy of the present method.
