文摘By self-made pulse electrical source and strong magnetic field solidification tester, the effect of strong pulse magnetic field on graphite morphology and solidification structure of gray cast iron was studied. The results show that the structure is remarkably refined after treated by pulse magnetic field, and the width of graphite flakes is decreased while the length is increased after a slight decrease. The solidification temperature and eutectic temperature are increased and the undercooling degree of eutectic transformation is decreased by magnetic field.
