Abstract
By studying several NiCoCr-based equiatomic medium-/high-entropy alloys (M/HEAs) with single face-centered cubic structures, in this work, we systematically investigated the key factors affecting the hydrogen embrittlement (HE) of these alloys, with particular emphasis on the deformation mechanism, hydrogen adsorption, hydrogen diffusion, and grain boundary chemistry. The FeNiCoCr HEA was significantly less susceptible to HE than the other alloys due to its lowest hydrogen concentration and the presence of Cr segregation. Mn alloying not only deteriorated the HE resistance but also greatly reduced the passivation film resistance in acidic media and chloride solutions.
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.
