摘　　要：目前人们对包晶凝固过程和机理的研究远没有单相和共晶体系那样深入,长期以来仅限于定性的描述,至今还没有形成较为完整的理论体系,也没有单相和共晶合金那样较成熟的凝固模型。本文评述了其近年来包晶凝固的理论、各种假设模型,讨论了定向凝固过程中组织,生长机制等。People do not understand the process and mechanism of peritectic alloys solidification so deeply com- pared with understanding of single phase and eutectic alloys. What people know is qualitative description for a long time. They neither have formed a relatively complete theoretical system so far nor built a relatively mature solidifi- cation model of single phase and eutectic alloys. Solidification theory and various hypothetical models of peritectic alloys have been reviewed in this paper. Microstructure and growth mechanism on directionally solidified peritectic alloys was discussed.
