中文摘要：
通过考虑相图计算公式中基本参数——熔化温度和熔化焓的尺寸效应与形状效应，研究了完全互溶的二元纳米金属微粒系统理想溶液的相图．研究结果表明，纳米微粒的相图也依赖于微粒的尺寸和形状因子．对Cr-Mo纳米微粒系统相图的计算结果表明，纳米微粒相图的固相线和液相线要比相应块体材料的固相线和液相线低，但与已报道的结果不同的是，固、液相线变化的幅度基本相同．这与本文目前不仅考虑了纳米微粒熔化温度的影响，还考虑了纳米微粒熔化焓的影响有关．
英文摘要：
The phase diagram of binary metallic nanoparticles has been studied by considering the size and shape effects on the melting temperature and melting enthalpy. It is found that the phase diagram of binary metallic nanoparticles depends on the particle size and shape. The calculated results on Cr-Mo system show that both the solidus and the liquidus of the phase diagram of nanoparticles are lower than that of the corresponding bulk alloy, and their variation amplitude are similar, which is different from the reported result, due to considering the melting enthaly.
