英文摘要	With the ability to model the pattern formation for solidification, a phase field model has been studied by many scientists. The phase field method has successfully been applied to predict microstructure evolution in metallic alloys such as dendritic solidification. Currently available models, however, are restricted to single grain. A new phase-field model for dendrite growth of multiple grains in multicomponent alloys is developed based on the Ginzberg-Landau theory and phase-field model of single grain. Taking Al-Cu-Mg alloys for example, coupled the concentration field, simulated the dendritic growth process of multiple grains during isothermal solidification. The result of simulation showed dendritic competitive growth of multiple grains; the regions between the secondary arms and grains have the highest concentration and reappeared the process of dendrite growth in practical solidification.
