摘　　要：综述了定向凝固包晶合金相和微观组织选择的理论模型和实验研究进展,分析相和微观组织的选择规律,同时讨论了对流对凝固微观组织的影响。依据国内外对包晶合金凝固的研究现状,提出进一步研究的方向。Directional solidification of peritectic alloys researched is very important since peritectic solidifications occur in many kinds of materials. Developments of research on both theoretical model and experimental results of phase and microstructure selection during directional solidification is reviewed, and the effect of convection on the microstructure is discussed in the paper. Finally, the problem for directional solidification of peritectic alloys were pretented in terms of the study about phase and microstructure selection in the world. The research developments direction in the future is also prospected .
