通过原位透射电子显微镜对纳米颗粒中合金相形成的研究表明，这些颗粒的相平衡与相应的块体材料的相平衡显着不同。基于热力学修正的理论研究，通过考虑影响纳米尺寸合金颗粒相平衡的因素，修正了 CALPHAD 数据库中块体材料的吉布斯自由能。事实证明，这项研究对于评估实验结果很有用。
A study on alloy phase formation in nanometer-sized particles by insitu transmission-electron microscopy revealed that the phase equilibrium of these particles is significantly different from that of the corresponding bulk materials. A theoretical study was conducted based on thermodynamics modified so that Gibbs free energies for bulk materials available in the CALPHAD database were modified by taking into consideration factors affecting the phase equilibrium of nanometer-sized alloy particles. The study proved useful to evaluate the results obtained from experiments.
