| Abstract Scope |
The interaction of hydrogen with metallic systems poses a significant challenge, particularly for the mechanical properties of metals, due to hydrogen embrittlement. This study investigates the influence of acoustic excitation on hydrogen desorption in metallic systems. A thermodynamic framework is developed to elucidate the favorable energetics for hydrogen removal under these conditions. This work examines the mechanistic interplay between hydrogen transport dynamics and microstructural modifications induced by these perturbations, using advanced characterization tools and in-situ techniques. The roles of acoustoelasticity and acoutoplasticity are examined across different strain-amplitude regimes for hydrogen mobility. Results indicate unconventional trends in strain amplitude, strain rate, and the sign of the applied stress for hydrogen removal. |
