Abstract:Microstructure evolution via deformation-induced martensitic transformation, void formation, and crack propagation is investigated in a metastable austenitic Cr-Mn-N stainless steel for up to 90°bending using a combination of electron backscattering diffraction and parent grain reconstruction. Stress-strain heterogeneity and stress triaxiality studied using finite-element analysis reveal that the inner and outer radii are in approximately uniaxial compressive and tensile stress states, respectively, with the o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
