Theoretical and experimental study of the gamma and gamma prime equilibrium in Ni-based superalloys.
Original language description
Ni-based superalloys with aluminium belong to systems with order-disorder transition. Because of the complexity of these alloys, quaternary systems can be taken as suitable and sufficiently representative model systems for a theoretical study of their phase equilibria. In recent years several assessments including various model descriptions of ordered phases and ordering based on the CALPHAD formalism have been made with the aim to describe phase diagrams of relevant binary, ternary and some quaternarysystems. For our study, the Ni-Al-Cr-Co system was chosen and phase boundaries were calculated based on the data for lower-order systems. The calculations were performed by means of the software 'Thermo-Calc'. Values obtained were compared with experimentally determined phase information. For better agreement of theory with experiment, an thermodynamic optimization was performed.
