Microstructure refinement of dual-phase steels with 3.5wt% Mn: Influence on plastic and fracture behavior
Abstract
The plastic and fracture behavior of ultrafine-grained dual-phase (UFG-DP) steels (Fe-0.1wt%C-3.5wt%Mn) were analysed from the comparison with the coarser grained DP microstructures taken as references. The UFG-DP steel exhibits a superior balance between strength, uniform elongation and true fracture strain. The higher mechanical performance is explained by both a size effect and a relatively high Mn content in austenite which lead to a …
