Predictions of Phase Equilibria
The TCS Ti/TiAl-based Alloys Database (TCTI) can be used to calculate phase equilibria, including phase fractions and compositions, to reliably account for phase transformations with light impurities (O, N, H, etc.) taken into account. Typical examples for titanium alloys are shown with the emphasis on validation against experimental observations in multicomponent commercial alloys.
