Abstract: Abstract Nitrogen-annealed tensile specimens of a cold rolled medium Mn (9.76 wt%) steel exhibited significantly reduced ductility due to a two-zone embrittled surface layer, imparted during annealing in a nitrogen atmosphere. The embrittlement was associated with high nitrogen contents at the surface. [ABSTRACT FROM AUTHOR]
