Abstract

The austenitic stainless steels in nuclear reactors suffer serious corrosion issues due to the the coupling effect of irradiation damage and hydrogen. Voids have a strong capability to trap hydrogen, reducing the corrosion resistance. There is still no effective strategy to improve the resistance to irradiation and hydrogen-induced corrosion. Here, increasing the alloying elements (Cr, Mo), and decreasing (Fe, Ni, Mn) can enhance the irradiation damage resistance of austenitic stainless steel, which changed defect type from voids to stacking faults, and further reducing hydrogen capture ability, resulting in enhanced resistance of irradiation and hydrogen-induced corrosion of austenitic stainless steel.

期刊介绍: Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
