摘要：
The effect of RE-modifier on the microstructure and mechanical properties of high carbon-medium manganese steel has been investigated in present work. The results showed that the RE-modifier can refine the crystalline grain of high-carbon medium-manganese steel. The shape and distribution of carbides are improved and the columnar grains and phosphide in grain boundary are eliminated. Consequently, the impact toughness of the steel is increased by more than one time, compared with no addition of RE-modifier.
