Abstract
The severe plastic deformation (SPD) technique has been widely used for grain refinement to produce bulk ultra fine-grained (UFG) microstructure. In this study, an improved corrosion-resistant material of type 304L stainless steel (SS) has been designed, from the coarse-grain (CG) microstructure to the UFG microstructure using the SPD technique through cryo-rolling at liquid nitrogen (at 77K) temperature followed by gamma-ray irradiation treatment. In comparison to the effect of gamma-ray on both CG and UFG microstructure, both specimens were irradiated with an equal amount of doses. Gamma (γ) ray irradiation (dose rate: 2.83 kGy/h) affected the corrosion resistance of AISI type 304L stainless steel (in both CG and UFG) in concentrated nitric acid (65 wt%) medium. The correlation of irradiation effects on the microstructure and nitric acid corrosion behaviors has been discussed, which is important for designing materials for application in nuclear-spent fuel reprocessing plants.
