| Abstract Scope |
Hydrogen, owing to its small size (second smallest), exists in metals as interstitial atoms in solid solution and exhibits high mobility even at room temperature. This study uses the acoustic field as a guiding tool to drive hydrogen in the metal matrix to the desired location. The mechanism governing acoustically driven hydrogen motion is investigated using FEM modeling, thermodynamic formulation, and in situ experiments. Results show that hydrogen redistribution behavior strongly depends on the local stress state and acoustic pressure, indicating competition between stress driven diffusion and defect mediated transport. |
