Abstract The pulsed magnetic field was applied into the solidification process of low carbon steel with titanium treatment without contact by the spontaneously developed device of pulse magnetic field generator, and the influence of pulsed magnetic field under different discharge voltage on macro morphology, dendrite and organization of the specimen was studied by metallographic microscope, scanning electron microscope and energy spectrometer. The results showed that the macro surface of the sample gradually became flat with the increase of discharge voltage. Furthermore, the dendrite and organization was gradually refined as the pulse magnetic field strength increased, but after reaching a certain strength, the opposite conclusion was obtained with continuously increasing the strength. Thus, it could be inferred that the influence of pulsed magnetic field intensity on dendrite and organization had an optimum value.
