应用快速扫描（或芯片）量热法系统地研究了两种近共晶金-锡组成物的成核动力学。测定的成核速率在有限过冷时达到最大值。实验数据与模型计算的比较表明，观察到的最大成核速率是由于深过冷液体中成核机制的转变。(C) 2017材料学报Elsevier Ltd.出版。版权所有。
Fast scanning (or chip-) calorimetry has been applied to systematically investigate the nucleation kinetics of two near eutectic Au-Sn compositions. The determined nucleation rates show a maximum at finite undercooling. A comparison of the experimental data with model calculations indicates that the observed maxima of the nucleation rates are due to a transition of the nucleation mechanism in the deeply undercooled liquid.
