Some illustrations of the use of deuterium or tritium for isotopic tracing of hydrogen absorption, transport and trapping in nuclear materials are presented. Isotopic tracing of hydrogen has been shown to be successful for the determination of the boundaries conditions for hydrogen desorption or absorption in a material exposed to a hydrogen source. Also, the unique capabilities of isotopic tracing and related techniques to characterize H interactions with point defects and dislocations acting as moving traps has been demonstrated. Such transport mechanisms are considered to play a major role in some stress corrosion cracking and hydrogen embrittlement mechanisms.This article is part of the themed issue 'The challenges of hydrogen and metals'.
本文展示了一些利用氘或氚对核材料中氢的吸收、传输和捕获进行同位素示踪的示例。氢的同位素示踪已被证明可成功确定暴露于氢源的材料中氢解吸或吸收的边界条件。此外，同位素示踪及相关技术在表征氢与作为移动陷阱的点缺陷和位错之间相互作用方面的独特能力也得到了证实。这种传输机制被认为在某些应力腐蚀开裂和氢脆机制中起主要作用。本文是主题为“氢与金属的挑战”的特刊的一部分。
