Abstract

Abstract The widespread use of hydrogen as an energy carrier is considered one of the most important keys to achieving the decarbonization necessary for the energy transition in numerous areas of technology and society. Not least due to the associated contact of metallic components with (pressurized) hydrogen, there is a latent risk of hydrogen-induced cracking (“hydrogen embrittlement”). The cause of damage is the hydrogen absorbed by the material, which is mobile via interstitial lattice diffusion. In high-strength steels with a tensile strength of more than 800 MPa, even very low diffusive hydrogen contents of less than 1 ppm (parts per million) can have a crack-inducing effect. Hence, dedicated, highly accurate analytical and testing methods are required for the detection of hydrogen and its effect on the mechanical properties of metals. This paper summarizes the current state of knowledge regarding hydrogen embrittlement and reviews the analytical, mechanical, and fractographic investigation methods for detecting hydrogen in metals.

金属中氢的冲击与检测
氢作为一种能源载体的广泛使用被认为是在许多技术和社会领域实现能源转型所必需的脱碳的最重要的关键之一。尤其是由于金属部件与(加压)氢的相关接触,存在氢诱发开裂(“氢脆”)的潜在风险。破坏的原因是材料吸收了氢,氢通过间隙晶格扩散而移动。在抗拉强度超过800mpa的高强度钢中,即使扩散氢含量非常低,低于1ppm(百万分之一)也会产生裂纹诱导作用。因此,需要专门的、高度精确的分析和测试方法来检测氢及其对金属机械性能的影响。本文综述了氢脆的研究现状,并对金属中氢的分析、力学和断口学检测方法进行了综述。
