Abstract

The mechanisms of disintegration of a metal melt formed during electrical explosion of aluminum foils are experimentally and theoretically investigated. The experiments were carried out on an experimental setup consisting of two current generators, one of them provided microwire explosion, while the other, an x-pinch radiograph, was used for diagnostics. In the experiments, the upper time limit of disintegration of metastable state of exploding aluminum foil was determined. For the metastable state of aluminum at internal energy of 3.5-4.5 kJ/g the calculated nucleation velocity exceeds 1014 cm-3 · s-1 and the critical nucleation energy is 9 ± 0.3 eV.
