摘要:

为深入研究应变时效对Q460C高强钢基本力学性能影响,建立考虑应变时效影响Q460C高强钢应力-应变本构关系曲线,对经应变时效影响的Q460C高强钢进行了试验研究,分析了Q460C高强钢经应变时效后基本力学性能指标,采用修正Ramberg-Osgood模型对试验结果进行拟合。结果表明:Q460C钢经预应变后具有显著的应变硬化现象,屈服强度得到大幅提高,极限应变和断裂应变显著降低,屈强比接近1.0,结构发生脆性断裂的可能性增加; Q460C钢经时效后产生时效硬化现象,试件在各时效之间应力-应变曲线差别较小,经时效硬化后钢材的硬化程度低于应变硬化; 采用修正的Ramberg-Osgood模型能够较为准确地拟合经预应变及时效影响后高强钢的应力-应变曲线,拟合结果与试验结果具有较好的一致性; 研究内容可为相关工程应用和理论分析提供参考。

Abstract:

To further study the effect of strain aging on the basic mechanical properties of Q460C high strength steel and establish the stress-strain constitutive relationship curve of Q460C high strength steel considering the effect of strain aging, the effect of strain aging on Q460C high strength steel was studied by experiment. The mechanical properties of Q460C high strength steel after strain aging were analyzed. The experimental results were fitted by modified Ramberg-Osgood model.The results show that Q460C steel has a significant strain hardening phenomenon after pre-straining, the yield strength is greatly improved, the ultimate strain and fracture strain are significantly reduced, the yield-strength ratio is closed to 1.0, and the possibility of brittle fracture is increased. Age hardening occurs in Q460C steel after aging. The difference of stress-strain curves between different aging is small. The hardening degree of Q460C steel after age hardening is lower than that of strain hardening. The modified Ramboerg-Osgood model can accurately fit the stress-strain curve of high strength steel after pre-strain and aging, and it is in good agreement with the experimental results. The research contents can provide reference for relevant engineering application and theoretical analysis.
