Abstract
The microstructure of the fusion boundary (FB) for cold worked (CW) 316LN stainless steel/Inconel 52 M weld joint (20 % CW 316LN/52M-FB) was investigated. The FB region was subjected to stress corrosion crack growth rate (SCCGR) test in simulated primary water of pressurized water reactor (PWR). It was noticed that stress corrosion cracking (SCC) occurred both along the FB and in the nearby 316LN region. The propagation of secondary cracks was impeded in the 52 M region rich in the Cr and Ni. Under similar conditions, the SCCGR of 20 % CW 316LN/52M-FB was five to six times higher compared with 316 L/52M-FB without CW.
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.
