(S271)Effects of Carbon and Nitrogen on Work Hardening Behavior of Metastable Austenitic Stainless Steel

摘要

Metastable austenitic stainless steels, such as SUS304, exhibit marked work hardening due to deformation-induced martensitic transformation, and thus, the cold-worked products of the steels are widely used as high strength sheets and wires. The addition of carbon and nitrogen is known to be effective method for further strengthening of the steels because the hardness of deformation-induced martensite is significantly increased. On the contrary, Tsuchida et al. (
