English abstract:
Eta phase stabilities were evaluated in consideration of new experimental data on the Ni-base superalloy, ATI718Plus. It has been found that the previously suggested miscibility between Ni3Ti (η-phase) and the Ni6NbAl compound (η*-phase) has been overestimated. A new thermodynamic model description is proposed which is also applicable to kinetic simulations of the precipitation evolution of η and η* in multi-component Ni-base superalloys.
