| Abstract | The effects of electropulsing treatment (EPT) on the microstructure and corresponding mechanical properties of a nano-lamellar 316L austenitic stainless steel were investigated. The original 316L stainless steel features a nano-lamellar framework with high density of dislocations via cold rolling. The nanostructured stainless steel was hardened and strengthened after EPT with relatively low discharge voltage, which may result from the cooperative effect of stable nano-lamellar structure and mobile dislocations recovery. Both the microhardness and tensile strength would decrease significantly with the increase of discharge voltage due to the nucleation and growth of recrystallized grains in the steel.; The effects of electropulsing treatment (EPT) on the microstructure and corresponding mechanical properties of a nano-lamellar 316L austenitic stainless steel were investigated.
