The relatively high dislocation density associated with bainitic ferrite can be attributed to a shape change accompanying the transformation which is accommodated at least …
웹2024년 9월 11일 · The substructure of granular bainite has been revealed by TEM; granular bainite is composed of parallel fine elongated platelets with a thickness of ∼0·5 μm. The parallel fine elongated ferrite platelets have a similar orientation and form a sheaf morphology, which is no different from that of ordinary bainite. 웹A bainite dual-phase (FB) steel containing polygonal ferrite and granular bainite is thermo-mechanically rolled, followed by an accelerated cooling. Two different cooling rates are applied to obtain two different materials. The aim of the study is to explore the reasons for the differences in the mechanical response experimentally observed for these two materials …
