Calculation of phase equilibria and evaluation of glass-forming ability of Ni-P alloys

Abstract

A thermodynamic evaluation of the Ni-P binary system has been made by employing the calculation of phase diagram (CALPHAD) method. A set of the thermodynamic parameters describing the individual phases of this system has been obtained from experimental information available in literature. Phase equilibria and thermochemical properties of this system are calculated using the obtained parameters. Moreover, the glass-forming ability of this system has been evaluated based on a simple kinetic model. The calculated glass-forming ability as well as the calculated phase diagram show good agreement with experimental data in literature. (C) 1999 Elsevier Science S.A. All rights reserved.
