The thermodynamic driving force for rapid crystallization of liquid metals, i.e.the Gibbs free energy difference △G_(LS) between undercooled liquid phase and product solid phase, is of essential importance for deepened investigations on rapid solidification such as the calculation of nucleation rate and the prediction of the formability of metastable phases as well as the feasibility of glass transition. An ultra-high-vacuum containerless processing technique by RF electromagnetic levitation melting was applied to undercoolliquid Fe and Ni by amounts up to 200 and 235 K. Specific heats of undercooled liquid Fe and Ni were measured by drop calorimetry and determined as. 48. 6 and 40. 5 J . mol ̄(-1) . K ̄(-1) respectively. On the basis of specific heat measurements, the △G_LS values of Fe and Ni were calculated according to its rigorous expression. Meanwhile, the theoretical models by Turnbull and Dubey-Ramachandrarao were also used to calculate the thermodynamic driving force approximately. It was found that Dubey-Ramachandrarao model usually showed smaller deviations but both models deviated significantly from the rigorous calculations provided that the undercooling exceeded 100 K. Since the deviation of approximated △G_(LS) value has a drastic influence on the calculation of nucleation rate in the undercooled liquid metals, it is necessary to do rigorous calculations about the thermodynamic driving force for any quantitative research on rapid crystallization.

采用超高真空无容器悬浮熔炼技术使液态Fe和Ni的过冷度分别达200和235K,借助量热法测定出其比热各为48.6和40.5J·mol~(-1)·K~(-1).据此精确计算出深过冷Fe和Ni快速结晶的热力学驱动力△G_(LS),并与Turnbull模型和Dubey-Ramachandrarao模型的近似计算结果相比较,发现这两种近似模型在过冷度超过100K时均产生大于1%的偏差.进一步分析发现,△G_(LS)的计算偏差对深过冷液态金属中晶体形核率的影响极大,因此快速凝固研究中应尽可能精确计算△G_(LS).
