摘　　要：在金属固态相变中,扩散型相变的珠光体转变涉及三相两界面的复杂过程。外加磁场将改变奥氏体向珠光体转变过程,对珠光体显微结构及宏观性能产生极大影响。本文综述了磁场对钢中珠光体相变的研究进展,阐述了磁场对扩散型相变的作用机制,主要讨论了强磁场对珠光体相变的奥氏体相区、铁素体、渗碳体的影响。最后对强磁场下珠光体相变未来研究提出了一些建议并进行了展望。In the solid phase transformation of metals, the pearlite transition of diffusive phase transformation involves the complex process of three phases and two interfaces. The external magnetic field will change the process of austenite transformed to pearlite, which has a great influence on the microstructure and macroscopic properties of pearlite. In this paper, the research progress of magnetic field on pearlite transformation in steel is reviewed, the mechanism of magnetic field on diffusion-type transformation is expounded, and the effects of high magnetic field on austenite phase region, ferrite and cementite are discussed. Finally, suggestions and prospects are also put forward for the future study of pearlite phase transition under the strong magnetic field.
