| Research Abstract |
It is well known that even the melting point, which is one of the most fundamental physical properties, can be changed by the surface or surface Gibbs energy in nano metals and alloys. Although it is possible to evaluate the decrease of the melting point and liquidus temperature in metals and alloys on the basis of thermodynamics, we need precise information on the interfacial Gibbs energy between solid and liquid phases. However, we have not yet developed an adequate experimental procedure and a calculation method to evaluate the interfacial Gibbs energy between solid and liquid phases in alloys. The purpose of this study is to establish those experimental and calculation procedures.
