Abstract

ABSTRACT In this study, the effects of room temperature static strain aging period on the tensile properties of DP600 dual-phase steel were investigated. 6% and 12% of pre-strained DP600 steels were carried out static strain aging treatment at room temperature for up to 4 months. It was observed that with increasing both pre-strain rate and room temperature static aging period, the tensile strength values increased and ductility values decreased significantly. Also, dual-phase steels maintain the continuous yield behaviour which is general characteristic. The fracture surfaces exhibited a lower depth dimple type mode with increasing room temperature static strain aging period.

商用双相钢室温下的长时间应变时效响应

本文研究了室温静态应变时效对DP600双相钢拉伸性能的影响。6%和12%的预应变DP600钢在室温下进行了长达4个月的静态应变时效处理。结果表明，随着预应变速率和室温静态时效时间的增加，拉伸强度值显著增加，延性值显著降低。此外，双相钢保持连续屈服行为，这是其一般特征。随着室温静态应变时效时间的增加，断裂表面呈现出较低深度的韧窝型模式。
