先进材料疑固实验室 Solute redistribution Laboratory of Advanced Materials Solidification Different solidification conditions can cause different distribution of solute concentration in the liquid and in the solid. There are four situations: Situation 1:Fully equilibrium solidification Situation 2:No solute diffusion in solid,complete solute diffusion and mixing in liquid. Situation 3:No diffusion in solid,Limited diffusion in liquid,no convection. Situation 4:No diffusion in solid,some convection in the liquid 上浒充通大学 SHANGHAI JIAO TONG UNIVERSITYSolute redistribution Different solidification conditions can cause different distribution of solute concentration in the liquid and in the solid.
