图解摘要 基于实验室的衍射对比断层扫描 (DCT) 应用于热处理的精益双相不锈钢 (DSS)，以观察注氢处理后的微观结构变化。研究了 DCT 技术对暴露于水溶液的双相材料进行原位评估的可行性，并在阴极充氢之前和之后进行了 DCT 观察。充电7天后观察到衍射斑的移动，这不能用样品横向移动来解释。这里介绍了一种应用 DCT 技术研究氢-微结构相互作用的实验方法，但需要更精确的实验方法来验证衍射斑的移动是否源于晶格参数的变化。
Graphical Abstract Laboratory-based diffraction contrast tomography (DCT) was applied to heat-treated lean duplex stainless steel (DSS) to observe microstructural changes by hydrogen infusion treatment. The feasibility of the DCT technique for the in situ assessment of a dual-phase material with exposure to aqueous solution was investigated, with DCT observations carried out before and after cathodic hydrogen charging. The movement of diffraction spots was observed after charging for 7 days, which cannot be explained by sample lateral movements. An experimental method to apply the DCT techniques for investigating the hydrogen–microstructure interaction is introduced here, but a more accurate experimental methodology is required to verify that the movement of diffraction spot derives from lattice parameter changes.
