Abstract:Herein, the microstructure and mechanical properties of a high‐carbon bainitic steel treated by long‐time bainitic austempering and short‐time austempering plus tempering processes are compared. The multiphase microstructures are characterized by dilatometry, X‐ray diffraction, scanning electron microscopy, and transmission electron microscopy to correlate with mechanical properties. Results show that although long‐time austempering treatment can reduce the volume fraction of brittle martensite, no significant… 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.
