摘要/Abstract

摘要： 用Gleeble热模拟试验机研究了0.06C-0.31Mo V-Nb-Ti-B微合金化钢再结晶区压下率(35.0%~ 52.0%)、非再结晶区压下率(60.2%～70.3%)、冷却速度(20~38 ℃/s)等轧制参数对钢的组织和机械性能的影响。试验结果表明，随着轧后冷却速度加大，上贝氏体的体积比增加导致钢强度的提高；贝氏体基体中针状铁素体含量越多，上平台能(USE)越大，韧-脆转变温度越低，因此，贝氏体基体中针状铁素体能改善管线钢的机械性能。

Abstract: The effect of rolling parameters such as 35.0%~52.0% reduction rate in recrystallization region,60.2% ~70.3% reduction rate in non-recrystallization region, cooling rate(20～38 ℃/s)on structure and mechanical properties of0.06C-0.31Mo V-Nb-Ti-B microalloying steel has been studied by Cleeble thermal simulation machine.The test results sbowed that with increasing cooling rate,the upper bainite volume percentage increased led to increasing strength of steel, and the more acicular ferrite content in bainite matrix the more upper shelf energy(USE)of steel and the lower ductile brit- tle transition temperature, therefore the acicular ferite in bainite matrix could improve the mechanical propertics of pipeline steel.
