本文综述了微结构氢映射技术的最新进展。以高空间分辨率，即在最精细的微结构特征尺度上绘制氢的图谱具有挑战性，这导致了各种方法的发展：热解吸谱、银装饰、氢微指纹技术、二次离子质谱学、原子探针断层摄影术、中子射线照相术和扫描开尔文探针。这些技术在与微结构敏感的氢检测相关的空间和时间分辨率方面具有不同的特征。将这些技术与其他微结构探测方法结合使用，可实现多尺度、定量、三维、高空间和动力学分辨率的氢作图，具体取决于所使用的特定多探针方法。在这里，我们简要概述了每种方法的具体特点以及它们在氢脆领域中的联合应用所产生的进展。
This paper gives an overview of recent progress in microstructure-specific hydrogen mapping techniques. The challenging nature of mapping hydrogen with high spatial resolution, i.e. at the scale of finest microstructural features, led to the development of various methodologies: thermal desorption spectrometry, silver decoration, the hydrogen microprint technique, secondary ion mass spectroscopy, atom probe tomography, neutron radiography, and the scanning Kelvin probe. These techniques have different characteristics regarding spatial and temporal resolution associated with microstructure-sensitive hydrogen detection. Employing these techniques in a site-specific manner together with other microstructure probing methods enables multi-scale, quantitative, three-dimensional, high spatial, and kinetic resolution hydrogen mapping, depending on the specific multi-probe approaches used. Here, we present a brief overview of the specific characteristics of each method and the progress resulting from their combined application to the field of hydrogen embrittlement.
