摘　　要：铁磁质、顺磁质或逆磁质材料，在强磁场下热处理或者凝固都得到类似的现象：晶粒细化及取向性，强磁场还可以改变材料的组织、诱发相变，许多研究者对磁场影响材料组织的机理进行深入的研究。最终得出结论：材料凝固过程中强磁场使得晶粒旋转，固态下强磁场使不同磁导率的组织分散均匀。本文综述了强磁场对材料组织和性能影响的进展。并提出展望。After annealing or solidification under high magnetic field, ferromagnetic, paramagnetic and diamagnetic material will have the same phenomena that grain will be orientated or refined. High magnetic field can change material structure and induce phase transformation. Many scientists use theory to explain the relation between high magnetic field and material property. It concludes that grain will be rotated while solidification, and different magnetic conductivity structure will be dispersed homogeneous while annealing. This article will summary both the latest improvemenl of theory and experiment result.
