Current-Driven Explosion of Micron Size Wires in Different External Media

A wire explosion in gaseous and condensed media extends possibilities of study of phase transitions of the wire material.

Description
Summary:A wire explosion in gaseous and condensed media extends possibilities of study of phase transitions of the wire material. In the present work we studied the influence of the external media on the explosion of micron-size wires by a nanosecond discharge. The 25 mum diameter copper, nickel and tungsten wires were exploded in vacuum, air, water and glycerine by current pulse with a rate increase of 50 A/ns. Energy deposited in the wires during the resistive phase of heating in the different media was estimated from the experiments.
