Abstract

The effects of thermodynamic properties on the phase stability of an imaginary A-B binary alloy nanoparticle system were examined using a regular solution model based on the CALPHAD method. When the two components of an alloy had the same melting points, both the liquidus and solidus temperatures decreased across the whole composition range, regardless of the sign of the interaction parameter. When the two substances had different melting points and Ω (solid) ≤ 0, similar behavior was observed. However, when Ω (solid) > 0, the solidus and solvus lines, and the eutectic composition move to the pure substance side that has the lower melting point.
