| 摘 要： | 采用化学分析、金相组织检验、力学性能检验和热处理实验等手段，对HRB335热轧带肋钢筋出现拉伸脆断和无屈服强度的异常现象进行分析。结果表明，HRB335热轧带肋钢盘出现一定量异常组织粒状贝氏体是拉伸脆断和无屈服强度现象的主要原因。 |
| 关 键 词： | HRB335热轧带肋钢筋 脆断现象 金相组织 力学性能 热处理 断口形貌 |

| Abstract: | By chemical composition snalysis,microstructure examination and heat treatment.the reason of the brittle fracture and on yield strength phenomenon in tensile rest of HRB335 hot rolled ribbed steel bar was analyzed.The results shows that the existence of a certain amount of abnormal granular bainite in the structure of HRB335 hot rolled steel bar is the main reason for no vield strength and brirrle fracture. |
| Keywords: | hot ralling ribbed stell bar brittle fracture yield strength granular bainite |
