- 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的影响。本文综述磁场对钢中珠光体相变的研究现状及研究进展,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有价值的建议,具有非常重要的指导意义。
In the solid phase transformation of metal, the pearlite transition of diffusive phase transformation involves the complex process of three phase and two interface. The external magnetic field will change the process of austenite to pearlite, which has a great influence on the microstructure and macroscopic properties of pearlite. In this paper,the researce status and progress of magnetic field on pearlite transformation in steel are 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, some valuable suggestions for the future study of pearlite phase transition under strong magnetic field are put forward, which has very important guiding significance.
