摘要:

氢渗透是诱发管线钢发生氢脆的关键因素,而引入合金元素则是提升管线钢力学性能和抗氢脆性能的有效手段。基于纯净体系中氢渗透行为的微观机理,系统总结了合金元素对管线钢氢渗透各关键环节的微观调控机理,包括氢分子的吸附与解离、氢原子在表面的吸附与渗透、体相内的溶解与迁移,以及缺陷处的偏聚行为。结果表明,单一合金元素掺杂可通过引发局部晶格畸变、重构电荷分布、改变成键特征、调控扩散势垒等微观机理,有效抑制氢渗透行为;多元素协同掺杂及多主元合金体系表现出更为复杂的调控机理,利用不同元素的协同效应可进一步增强对氢渗透行为的抑制作用。后续研究可围绕多元素协同掺杂的作用机理解析、高熵合金的成分优化设计、合金元素对复杂缺陷环境下氢捕获及氢偏析的调控机理,以及多尺度模拟方法开展进一步研究,以期为新型抗氢脆材料的合金化设计提供理论依据。

Abstract:

Hydrogen permeation is a pivotal factor inducing hydrogen embrittlement (HE) in pipeline steels. Alloying presents an effective strategy for enhancing both the mechanical properties and HE resistance of these steels. In this review, the atomistic regulating mechanisms of alloying elements on critical steps of hydrogen permeation in pipeline steels are systematically summarized. The hydrogen permeation is considered to involve four critical steps: the adsorption and dissociation of hydrogen molecules, the adsorption and permeation of hydrogen atoms on the surface, the dissolution and migration in the bulk phase, and the segregation behavior at defects.The results show that single alloying element doping can effectively inhibit hydrogen permeation by inducing local lattice distortion, changing charge distribution, regulating bonding characteristics or increasing energy barriers. Furthermore, multi?elements synergic-doping and multi-principal element alloy systems exhibit more complex regulation mechanisms,and the synergistic effect of different elements can further enhance the inhibitory effect on hydrogen permeation. Future research can focus on the effect of multi-elements synergic-doping, the optimization and design of high-entropy alloys, hydrogen trapping under environments with complex defect structures and the development of multi-scale simulation methods, aiming to provide theoretical guidance and design strategies for advanced materials resistant to hydrogen embrittlement.
