Abstract Scope |
Hydrogen embrittlement is one of the most significant challenges limiting the use of high strength alloys. Despite the tremendous research effort invested, investigations on hydrogen embrittlement still suffer from experimental challenges in analyzing hydrogen content, kinetics of hydrogen diffusion, and hydrogen-microstructure interactions. To this end, novel in-situ methods are needed, that simultaneously enable high-resolution mapping of microstructure, while detecting diffusible hydrogen. Here in this talk, we will present progress towards an integrated thermal desorption spectroscopy - scanning electron microscopy (SEM) method, which employs a recently developed in-situ SEM hydrogen charging setup. Current research case studies include in-situ analyses that couple the spectroscopy data with data from other SEM-based techniques, such as electron-backscattered diffraction and electron channeling contrast imaging, to understand hydrogen induced microstructural stresses, phase transformations, and dislocation restructuring. |
