摘要	A surface layer with a gradient decrease in twin density has been produced in a Fe-Mn austenitic steel, which corresponds to a gradient drop in hardness from 5.3 GPa in the top surface to 2.2 GPa in the coarse grained core. The dependence of hardness on the twin thickness was determined, showing a weaker strengthening effect of twin boundaries than that of conventional grain boundaries in this alloy. Superior strength-ductility synergy was observed in tensile tests of the gradient nanotwinned layer. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
