An AISI 420 martensitic stainless steel, 0.6 mm thick was melted with a 4.4 kW continuous wave Nd: YAG laser in order to induce a certain proportion of retained austenite in a matrix. The volume percentage of the retained austenite (RA) in the melted-surface layer was investigated by irradiating the surface at different processing conditions.
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.
