Abstract
The phase equilibria in the Cu-Fe-Ta ternary system at 1000, 1100 and 1200 C have been experimentally determined by optical microscopy, electron probe micro-analyzer and x-ray diffraction on ternary equilibrated alloys. The Cu-Ta binary system was reassessed and the thermodynamic assessments of the Cu-Fe-Ta ternary system were carried out by using calculation of phase diagrams method on the basis of the experimental data investigated in the present work. A consistent set of the thermodynamic parameters leading to reasonable agreement between the calculated results and experimental data was obtained in the Cu-Ta and Cu-Fe-Ta systems.
