| Abstract: | On the basis of the heat conduction equation which has been already brought forward in prophase,the abnormal phenomena of specific heat and thermal dilate coefficient of iron-magnetism stuff nearby the phasetransformation point are used to establish the heat conduction equation involving the effect of magnetic field. Bymeans of FEM software ANSYS 's coupling function of heat and magnetism, the temperature field of thequenching process of middle-carbon steel is analyzed and a solution of the distribution of transient temperatureis obtained. |
