Marangoni convection during solidification or remelting process was investigated in a small pool of liquid Fe-O alloy by experiments and numerical simulations. Most of studies in such a system with low Prandtl but high Schmidt number have took into account the thermocapillary convection but have left the solutocapillary effect out of consideration. However our experimental and numerical approaches revealed that solutocapillary convection also played an important role to cause some peculiar flow patterns with single roll cell or two roll cells. Marangoni convection obtained was classified to at least four categories based on the thermocapillary and the solutocapillary forces.Marangoni convectionthermocapillary forcesolutocapillary forcesolidificationremeltingFe-O alloy
