Grain refinement can greatly enhance the material mechanics, magnetism and other physical properties. Exploration of grain refinement methodology has been one of the hottest fields of material research. Among all the methods, deep supercooling technology is an effective way to refine the grains. In this paper, the grain refinement mechanism has been explored by deep supercooling and rapid solidification technique with introducing grain refined process of pure metal, binary uniform crystalline alloy and the binary eutectic alloy. Furthermore, peritectic grain refinement mechanism and rapid solidification technique have been discussed.
