| Abstract: | The effects of RE compound modificator on the mechanical properties and microstructure of high carbon high speed steel used for roller ring were investigated by SEM, EDS and EPMA. The results showed that the grain is refined, the morphology and distribution of carbide and inclusion are improved by RE compound modifying treatment. Compared with the high carbon high speed steel without modification treatment, the impact toughness is increased by 73.6 %, with same hardness. |
| Keywords: | high carbon high speed steel centrifugal casting modification microstructure mechanical property |
