## Abstract The effects of RE (La and Ce) on toughness of 30CrMnSi wearβresistance cast steel have been investigated by means of analysing microstructures and mearsering the properties of the steel with and without RE. The results show that RE can refine the asβcast microstructures, hinder or elimi
