摘　　要：简要回顾了强磁场在铁基材料领域的发展和应用历史。简述了强磁场影响奥氏体分解的基本原理。强磁场升高铁基材料中马氏体、贝氏体、珠光体、铁素体的转变起始温度,加速其转变行为。强磁场作为材料热处理的新手段,对于材料组织和性能控制具有重要作用。如何定量控制强磁场对铁基材料的相变与析出等还有待于更深入的研究。The development and application of high magnetic field in metallic materials research are precisely presented.The basic principles of influence of high magnetic field on the decomposition of austenite are described.Effects of high magnetic field on martensitic,bainitic,pearlitic and ferritic transformation temperatures,transformation behavior and transformed structures in Fe-based alloys are briefly reviewed.The start transformation temperatures are increased and the transformation behavior is accelerated by applying high magnetic fields.Being a new approach,high magnetic field plays an important role in the control of structures and properties of materials.Quantitative control of transformation and precipitation by applying high magnetic fields remains to be further investigated.
