摘　　要：在热处理过程中，通过外加磁场来改善被处理金属材料的力学性能是国际材料研究的一个重要的发展方向，一些学者利用在淬火过程中外加磁场来达到改变金属组织和性能的目的。本文在前期已提出的热传导方程的基础上，从变分原理出发，推导了磁场淬火温度场的有限元方程。得到的温度场计算结果与实验测试结果基本符合。at present, in heat treatment process, the methods of improving mechanical properties of metal materials by means of additional magnetic field is an important development tendency in international material study. Some scholars begin to utilize the quenching by additional magnetic field to change the organization and capabilities of the metal. In this paper, on the basis of the heat conduction equation that has already been brought forward in prophase, the finite element equation of temperature field in magnetic field quenching is derived by variational principle. Then the distribution of temperature field is simulated and testing is carried through.
