Abstract

The Ni-Ti-C ternary phase diagram is constructed via two steps. In the first step, all of the experimental phase diagram data available from the literature were critically reviewed and assessed by using thermodynamic models for the Gibbs energies of individual phases. In the second step, samples were prepared by are melting of cold-pressed pelletsand annealing at 900 degrees C for 288 h. Water-quenched samples wereanalyzed by using X-ray diffraction (XRD), optical microscopy, scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS) and differential thermal analysis (DTA) techniques. A consistent thermodynamic data set for the Ni-Ti-C system is finally obtained by considering the experimental results from the present work and reliable literature data. Comparisons between the calculated and measured phase diagrams show that most of the experimental information is satisfactorilyaccounted for by the thermodynamic modeling.
