| Research Abstract |
High temperature liquid alloy is the source of various kinds of metal material. The solute segregation and its morphology heavily depend on the solidification speeds, although the process is extremely complex. The aim of this research is to control the solute segregation and morphology in the resulting solid layer with modulating the temperature of the cooling surface, on which the solid layer forms. The research is focused on the design of the solute segregation position and the size of morphological structure in the solidified layer. In order to develop the necessary technologies, the present work bases its foot on the heat transfer and fluid mechanics of double diffusive convection system. The acquired knowledge will serve as fundamentals for developing new functional metal alloys.
