It was found that the volume fraction of martensite increased with increasing annealing temperature. Rotating bending tests (10 million cycles) were conducted on the as-received materials and the dual-phase steels specimens selecting completely reversed cycle of stress. It was seen that the fatigue strength of dual-phase steels increased when compared with as-received materials. The highest fatigue strength was observed in the intercritically annealed steels at 760 °C. The fatigue strength of these steels increased at the annealing temperature up to 760 °C and decreased at the annealing temperatures higher than 760 °C.eninfo:eu-repo/semantics/closedAccessFatigue-EAnnealingFatigue of materialsDual-phase steelsCarbon steelFerrous metalsRotating bending testsAnnealingQuenchingMartensiteMetallographic microstructureStrength of materialsStressesVolume fractionCarbon steelMetallographic microstructureFerrous metals and alloys-AHeat treatment-CMicrostructure-FMartensite microstructural morphologyTensile propertiesDeformationBehaviorArticle0002477861000112-s2.0-3424970189418271835286Materials science, multidisciplinaryDual Phase Steel; Martensite; Dp600
