摘要
The microstructures of Fe-Cr-B alloys after modification with rare earth(Ce) were investigated.The experimental results show that the as-cast modified micro-structures of Fe-Cr-B alloys are much finer and the original distribution of M_2B borides at grain boundaries in the continuous network modes was changed into broken network granular particales,indicating that the rare earth(Ce) has significant modification effect on the microstructures of Fe-Cr-B alloys.
