使用原位透射电子显微镜研究了 Ag-Pb 合金纳米颗粒的共晶转变。研究发现，Ag-Pb合金纳米粒子的共晶温度随着粒径的减小而降低。获得了共晶温度与颗粒半径倒数的线性关系。基于热力学理论的理论计算也表明共晶温度与半径倒数之间存在线性关系。计算结果与实验观察结果非常吻合。 (C) 2011 年美国物理研究所。 [doi:10.1063/1.3558921]
The eutectic transition of Ag-Pb alloy nanoparticles was investigated using in situ transmission electron microscopy. It was found that the eutectic temperature of Ag-Pb alloy nanoparticles decreased with decreasing particle size. A linear relationship was obtained for the eutectic temperature as a function of the reciprocal of the particle radius. Theoretical calculations based on the theory of thermodynamics also suggested a linear relationship between the eutectic temperature and the inverse radius. The calculated results were in good agreement with the experimental observations. (C) 2011 American Institute of Physics. [doi:10.1063/1.3558921]
