| 摘 要： | 在超高强度管线钢中添加不同数量的Mo与B,研究了不同Mo/B(s)比(B(s)为酸溶硼)的管线钢的组织相变特性和显微硬度的变化.结果表明,Mo-B(s)共同作用有利于提高钢的淬透性,增加组织中的下贝氏体含量,提高该钢的显微硬度,其共同作用的效果优于两者单独作用之和.在Mo-B(s)共同作用下,钢中的Mo/B(s)比RMo/B(s)=200时,该钢得到最佳的组织和最高的显微硬度.对有关作用机理进行了讨论. |

| Abstract: | The transformation characteristic, microstructure and micro-hardness for ultra high-strength pipeline steels with different content of Mo and B as well as different Mo/B ratio were investigated in this paper. Combined additions of Mo and B were found to more effectively increase the hardenability of the steel than the individual effectiveness of these two elements, which increase the volume fraction of bainite in microstructure and enhance the hardness of the steel. The experimental results showed that there should be an optimum Mo/B ratio to achieve the optimum microstructure and mechanical properties of the steel. The mechanism for the combined Mo-B effect on ultra high-strength pipeline steels was also discussed. |
| Keywords: | ultra high-strength pipeline steel Mo-B addition transformation microstructure microhardness |
