Abstract
Magnesium (Mg) is one of the most plentiful elements in
the Earth’s crust and seawater. It possesses low density, high
specific strength, high standard potential, and good biocom-
patibility. In addition, magnesium hydride shows the highest
energy density of all reversible metallic hydrides applicable
for hydrogen storage. These unique features make Mg and its
alloys a class of very promising material for structural and
functional applications pertaining to aerospace, transporta-
tion, and biomedical and energy sectors. Wide applications of
Mg alloys are thus deemed to significantly contribute to the
ever-increasing environmental problems and energy chal-
lenges in the worldwide. [...]
