Prediction of Metastable and Stable Phases

With so many binary and ternary systems assessed, many multicomponent alloys can be accurately described with the TCS Ni-based Superalloys Database (TCNI).

Ni-18Cr-18Fe-3Mo-0.5Al-1Ti-5.3Nb-0.02C Alloy

This example calculates the metastable phase equilibria in a 718-type alloy when all phases are suspended except FCC_L12 and BCT_D022 phases.
