| 摘 要： | 对屈服点不明显的20MnSiNb热轧带肋钢筋进行了断口观察、化学成分测定及显微组织分析，并与力学性能正常的钢筋进行了对比。研究表明，贝氏体含量偏高是造成钢筋屈服不明显的主要原因。并提出了改进措施。 |
| 关 键 词： | 20MnSiNb钢 热轧带肋钢筋 屈服点 |

| Abstract: | In order to find out the reason of no-yield-point of 20MnSiNb hot rolled ribbed bar,the fracture observation,chemical composition and microstructure were analyzed,and the comparison and analysis of normal mechanical properties were made as well.The results showed that the reason was the high content of bainite,and the measures were proposed. |
| Keywords: | 20MnSiNb steel hot rolled ribbed bar yield point |
