Abstract Scope |
Hydrogen embrittlement (HE) has been a concern in the reactor vessels of nuclear plants, hydrogen gas transport pipelines, and aerospace industries, causing catastrophic failures of high-strength components. Despite the significant impact of HE, experimental studies still suffer from difficulties in investigating diffusible hydrogen effects. The small size and high diffusivity of hydrogen atoms make it challenging to detect and track the volumetric changes caused by hydrogen in materials or the corresponding impact on microstructure and damage evolution. In this talk, we will discuss the role of radiation-induced defects during the HE process using coherent X-ray imaging (CDI) in real time. CDI is used to image the lattice strain and defect dynamics during the hydrogen absorption and desorption process. |
