The formation of strata during fast electrical explosions of aluminum wires at current densities of (1-1.4) × 108 A/ cm2 has been studied experimentally. To observe the strata, the soft x radiation generated at the hot point of an x -pinch was used. It has been revealed that strata are formed before the voltage collapse, that is, at the stage of heating of the wire metal. Two wire explosion modes were realized: with and without cutoff of the current carried by the exploding wire. Analysis of the experimental results shows that the stratification is most probably due to the thermal instability that develops as a consequence of the increase in metal resistivity with temperature.
