Deterioration in mechanical properties of materials due to hydrogen is called hydrogen embrittlement, which often leads to their catastrophic failures. In order to understand the mechanisms of hydrogen embrittlement and mitigate its influence, it is necessary to examine the role of defects in materials such as grain boundaries, dislocations and stacking faults, as hydrogen trapping sites. We will present two different charging routes for charging the site-specific APT specimens with deuterium in this talk, i.e., the cathodic charging in an electrolytic cell and the gas charging in a Reacthub Module. We will discuss the workflows involved in both the charging methods and the preliminary results concerning the deuterium charging of a TWIP steel specimen .
