“…In the present manuscript, at first, the validity of ESL technique for the study of supercooling of liquid metals was investigated by the survey of cooling curves of many liquid metals with high T m originally obtained in the experimental studies of many physical properties, such as density, surface tension, viscosity, thermal conductivity, and heat capacity. 11,12) In the next stage, this ESL technique was applied to the study of the supercooling for the homogeneous liquid phase of eutectic Ni-Nb system whose eutectic point is present at 40.5 at% Nb and 1448 K. 20) The particular feature of the result in the present study, a poor supercooling tendency around the eutectic composition, was discussed with the relation to the knowledge recently found, 17,[21][22][23][24] the existence of concentration fluctuations in the homogeneous liquid phase near the eutectic point.…”
