The modeling of non-isothermal dendrite growth in Pb-Sn alloy was conducted based on the phase field method to visualize the evolution of interface morphology of dendrite and to examine the effects of phase parameters on it. The results indicate that the dendrite mosphology is dependent on the under-cooled degree

coupled parameters and anisotropy value. The trapped melt packets and side branches can be greatly suppressed by an anti-trapping current. Furthermore

the relationship between anisotropy and dendrite tip velocity was described.
