摘要：
It is shown that the explosion of a conductor heated by a high-power current pulse is initiated by the nuclei of liquid phase that appear in the layer of a supersaturated vapor surrounding the liquid current-carrying core. The instant of electric explosion and the expansion velocity predicted by this scenario are confirmed by the experimental and computational data on current-induced heating of a tungsten conductor.
