【Abstract】 Effect of RE modification and heat treatment on carbide morphology and impact toughness of high C-Cr cast sieel were studied. Results show that RE and heat, treatment improves the morphology and the distribution of carbide and increases the impact toughness of high C-Cr cast steel. Function of RE and heat treatment combining results is remarkable.更多还原
