AbstractA nanotwinned 316L austenitic stainless steel was prepared by means of surface mechanical grinding treatment. After recovery annealing, the density of dislocations decreases obviously while the average twin/matrix lamella thickness still keeps in the nanometer scale. The annealed nanotwinned sample exhibits a high tensile yield strength of 771 MPa and a considerate uniform elongation of 8%. TEM observations showed that accommodating more dislocations and secondary twinning inside the nanotwins contribute to the enhanced ductility and work hardening rate of the annealed nanotwinned sample.
