Method of Making a nanostructured Austenitic Steel Sheet

Summary

A method for producing a nanostructured austenitic sheet by consecutive martensite and austenite phase (γ/α′) transformations, in which the coarse grained austenite sheet transforms to nanocrystalline martensite by strain-induced transformation, and then generates reverse transformation to nanostructured austenite by warm rolling due to dynamic recrystallization.
