Modern high strength steels for the automotive industry consist of several phases and phase mixtures. One important phase mixture is bainite consisting of ferrite and carbides. The main focus of this work was the characterization of different forms of bainite. For this purpose, micro-structure, transformations and mechanical properties of low-alloyed, fully bainitic steel sheets have been characterized and classified depending on the overaging temperature and the silicon content. Three temperature ranges of different characteristic structures, transformations and mechanical properties could be identified and categorized.
