Effect of forming strain on low cycle, high cycle and notch fatigue performance of automotive grade dual phase steels: a review
TL;DR: In this article , the impact of tensile pre-straining on the performance of automotive grade dual-phase steels was investigated, and the most significant improvement in HCF life and deterioration in LCF life were observed for equi-biaxial and orthogonal tensile pretraining conditions due to the rotation of maximum shear stress plane and the deformation concentrated region around the hard martensite.

Strain ratio effects on microstructure discovery and low-cycle fatigue behavior of DP600 steel under cyclic shear path
TL;DR: In this article, the fatigue behavior of dual-phase steels (DP600) under cyclic shear path is studied and the effects of strain ratio are analyzed. Based on twin bridge shear specimens, complete reverse strain-controlled fatigue tests are carried out on DP600 sheet (1.2mm) under different strain ratios (R = ǫ−1, −0.5, 0, and 0.5).
