Strength of solid and molten aluminum under dynamic tension
AE Mayer and PN Mayer, JETP LETTERS, 102, 80-84 (2015).
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.
