采用基于CALPHAD方法的规则溶液模型，研究了热力学性质对假想的A-B二元合金纳米颗粒体系相稳定性的影响。当合金的两个组分具有相同的熔点时，液相线和固相线温度在整个组成范围内都降低，而不管相互作用参数的符号。当两种物质具有不同的熔点和Omega（固体）0时，固相线和固溶线以及共晶成分向具有较低熔点的纯物质一侧移动。(C)2008爱思唯尔有限公司保留所有权利。
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 Omega(solid) 0, the solidus and solvus lines, and the eutectic composition move to the pure substance side that has the lower melting point.
