Abstract
The diffusion triple and electron probe microanalysis (EPMA) techniques have been adopted to study the isothermal section of the Ni-Al-Mo system at 1373 K. Experimental data from present work and literature have been assessed to evaluate the thermodynamic parameters of the ternary system by means of the calculation of phase diagram (CALPHAD) method. A substitutional-solution model is used to describe liquid, fcc, and bcc phases, while a sublattice model is used to describe intermetallic phases. Two sets of thermodynamic descriptions have been obtained, and comparison has been made between them. Also, calculations of equilibrium-phase diagrams compared to the experimental data have been presented. There is good agreement between the calculations and the experimental data.
