摘要
本文研究了稀土复合变质剂对Si-Mn系中碳贝氏体钢组织、冲击韧性和硬度的影响。试验结果表明 ,稀土复合变质对Si-Mn系贝氏体钢组织、冲击韧性和硬度影响较大 ,且存在一个稀土复合变质剂最佳加入量。
The effect of RE multiple modification on structure and impact toughness and hardness in Si-Mn and bainite cast steel has been studied. The test shows that the structure and impact toughness and hardness have been affected greatly by RE multiple modification in Si-Mn middle carbon bainite cast steel. In addition, there is an optimization addition.
