Abstract
The hydrogen-induced cracking behavior and mechanism of an L12-strengthened Ni50Cr20Co15Al10V5 high entropy alloy was evaluated using the tensile test after hydrogen charging. The microstructures and hydrogen-induced cracks were characterized by electron backscatter diffraction and electron channeling contrast imaging methods. The results revealed that hydrogen decreased the strain hardening rate and induced pronounced cracks, leading to significant degradation in elongation. After deformation, the local strain was concentrated in the precipitate-matrix interfaces. The precipitate-matrix boundary and the interior of precipitates were prone to hydrogen embrittlement, where hydrogen-induced cracks tended to propagate, attributing to the hydrogen-enhanced decohesion mechanism.
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.
