In this study, we investigate the relation between microstructure and fatigue crack propagation mechanisms in three commercial hot-rolled thick-plate advanced high-strength steels (AHSSs), namely 800CP, 700MC, 700MCPlus, compare them with a conventional low-alloy (HSLA) steel, 500MC, commonly used heavy-duty vehicle chassis production. Tensile testing, growth rate (FCGR) assessments have been conducted, controlling performance of these are comprehensively examined through characterization...
Complex-phase (CP) steels, with a multiphase microstructure, offer an excellent combination of high strength, ductility, and formability, making them attractive alternative to conventional high-strength low-alloy (HSLA) steels in the automotive industry. However, microstructure fatigue property relation CP is complex. This limits full exploitation applications, such as heavy-vehicles, where performance thick-plates after punching holes critical parameter. In this work, we initiate study...
