Mechanical spectroscopy techniques have been employed to investigate relaxational and structural damping processes in nanocrystalline magnesium hydride. The results are correlated to hydrogen anelastic relaxation processes and structural transformation of magnesium hydride to magnesium during hydrogen desorption. Microstructural modification strategies able to assist hydrogen release are discussed.

Abstract
Mechanical spectroscopy techniques have been employed to investigate relaxational and structural damping processes in nanocrystalline magnesium hydride. The results are correlated to hydrogen anelastic relaxation processes and structural transformation of magnesium hydride to magnesium during hydrogen desorption. Microstructural modification strategies able to assist hydrogen release are discussed.File in questo prodotto:
