Abstract

The concealment and delayed characteristics of hydrogen embrittlement (HE) pose significant challenges for the development of hydrogen-resistant materials. As a novel category of multi-principal-element alloys, high-entropy alloys (HEAs) have emerged as ideal candidates for the next generation of hydrogen-resistant alloys due to their unique design philosophy, which endows them with excellent mechanical properties, corrosion resistance, high-temperature stability, and hydrogen embrittlement resistance. In recent years, research on the hydrogen embrittlement resistance of HEAs has attracted extensive attention. This review systematically summarizes the hydrogen embrittlement mechanisms in both conventional alloys and HEAs, critically analyzes the contradictions and controversial issues in the current literature, proposes design strategies for hydrogen embrittlement-resistant HEAs, and discusses future research directions in this field.

摘要

氢脆（HE）的隐蔽性和延迟特性给耐氢材料的开发带来了重大挑战。作为一类新型的多主元合金，高熵合金（HEAs）因其独特的设计理念而成为下一代耐氢合金的理想候选材料，这使其具有优异的力学性能、耐腐蚀性、高温稳定性和抗氢脆性能。近年来，关于高熵合金抗氢脆性能的研究受到了广泛关注。本综述系统地总结了传统合金和高熵合金中的氢脆机制，批判性地分析了当前文献中的矛盾和争议问题，提出了抗氢脆高熵合金的设计策略，并讨论了该领域未来的研究方向。
