Abstract
Under dynamic loading, an aluminum melt has a comparable or even
higher strength than solid aluminum at room temperature. This phenomenon is
possible due to the uniformity of the melt and the homogeneous nucleation of
voids within it, whereas the fracture mechanics of a solid are controlled by
pre-existing defects. High-current electron irradiation of an initially solid
metal plate can be used to observe this effect.
