To obtain high strength and excellent deformability for ferrite/bainite dual-phase (F/B DP) pipeline steel for gas pipelines based on strain-based design, the volume fractions of ferrite and bainite should be considered first.
In this work, abstract representative volume elements (RVE) of finite element models (FEMs) of mesostructure for F/B DP pipeline steel with volume fractions of bainite between 30% and 58% were established, and the effects of volume fraction of bainite on the tensile properties and deformation compatibility were studied.
Results show that the stress and strain in the mesostructure were primarily distributed in the bainite and ferrite, respectively, and strain concentration occurs at the ferrite/bainite interface.
With increasing volume fractions of bainite, the strain localization factor (SLF) and strain ratio of ferrite with bainite (εF/εB) decrease, which can improve the deformation compatibility of the F/B DP pipeline steel.
However, the stress ratio of bainite with ferrite (σB/σF) and the contributions of bainite to stress and strain sequentially increase, and, as a result, the strength increases and the ductility decreases.
Therefore, a balance of strength and deformability can be obtained when the optimal volume fraction of bainite is in the range of 40% to 48%.
