摘    要:了在低碳锰铌钢的奥氏体向铁素体和珠光体墨迹的过程中外加稳恒磁场的晶粒细化作用。实验结果表明:稳恒磁场对相变过程中的晶粒细化有影响。在本的实验条件下,随上加磁场磁通密度的增大,昌粒尺寸减小。在磁通密度为1.5T时,昌粒尺寸为不加磁场时线性尺寸的60%。强磁场作用于相变时引起的高温钢辐射散热 加是导致晶粒细化的主要原因之一。由于在稳恒磁场中低碳钢的磁导率较大,磁场的产董的晶粒细化作用使试样组织的均匀

Abstract:The effect of stable magnetic field on grain refinement was investigated in the case of low carbon Mn Nb steel transformation from austenite to ferrite and pearlite. The result showed that the stable magnetic field has effect on transformation. The grain size decreases when the flux density is raised. When the stable flux density is 1.5 T, the grain size is 60 % of normal grain. One of the main reasons of grain refinement is that radiation increases for hot steel with magnetic field. Medium and low carbon steel have higher magnetic conductivity in magnetic field, so their microstructure become homogeneous by grain refinement.
Keywords:magnetic field treatment  grain rifinement  transformation
