| Abstract Scope |
Advanced high strength steels (AHSSs) with excellent mechanical properties are developed in recent decades to meet the requirement of lightweight design for automobiles. Medium Mn steels, one of the third generation AHSSs, have captured various attention due to remarkable mechanical performance. Thus, unveiling and understanding the deformation behavior in medium Mn steel is urgently needed. Here, the deformation behavior in 5Mn steel is in-situ investigated under a wide range of strain rates using the digital image correlation (DIC) technique. Results show that the Portevin-Le Chátelier (PLC) effect occurred when 5Mn steel deformed at all strain rates. Type A PLC bands happened at a strain rate of 10-3 s-1, corresponding to a moderate mechanical stability of austenite. With the increasing strain rate, multi-band was observed during deformation process in order to be in accordance with the high speed deformation. |
