Nucleation and Growth of 先进材料疑固实验室 solid Laboratory of Advanced Materials Solidification Nucleation is the process through which unstable solid embryos in the liquid becomes stable nuclei. It is the birth of solid. Nucleation of solid is a complicated process: Liquid may have to be cooled to a temperature lower than the liquidus temperature. Heterogeneous particles(grain refiner particles)are easily to catalyze the nucleation of liquid. nced Matere 上浒充通大学 SHANGHAI JIAO TONG UNIVERSITYNucleation and Growth of solid Nucleation is the process through which unstable solid embryos in the liquid becomes stable nuclei.
