Effect of RE Modification and Heat Treatment on Carbide Morphology and Impact Toughness of High C-Cr Cast Steel

研究了稀土与热处理对高碳铬铸钢碳化物的形态及冲击韧性的影响。结果表明,稀土和热处理均能改善高碳铬铸钢碳化物的形态与分布,提高其冲击韧性,尤其稀土与热处理共同作用时,效果更显著。

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.
