Nanosecond electrical explosion of micron diameter wire

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

Copper, nickel, tungsten, brass, stainless steel, aluminum and molybdenum wires of diameter d = 25 µm were exploded in vacuum, air and water by a current pulse with a growth rate of ∼ 50 A/ns. Energy deposited into the wires at different stages of heating in the media and vacuum was estimated from the experiments. Optical images of the exploded wires at different time moments were obtained. In accordance with the characteristic features of current and voltage waveforms as well as shadowgraphs we subdivide nanosecond explosions into 3 groups; under such division inside of each of them there are metals of closer thermophysical properties.
