Damage in aluminum, zinc and tin from a nanosecond electric pulse discharge

Microstructural effects associated with an electrical pulse discharge of 36 ns duration on aluminum, zinc and tin samples have been investigated. These experiments were conducted in air as well as in a pure N 2 atmosphere. The effects of spark gap distance, operating potential and discharge gas pres...

Zusammenfassung:	Microstructural effects associated with an electrical pulse discharge of 36 ns duration on aluminum, zinc and tin samples have been investigated. These experiments were conducted in air as well as in a pure N 2 atmosphere. The effects of spark gap distance, operating potential and discharge gas pressure were studied. A linear relationship between the crater diameter and the operating potential or discharge gas pressure was observed. Adjacent to the damage site, plastic deformation in the form of slip as well as a concentric ripple pattern was observed. These latter effects are similar to the deformation behavior associated with damage from a short duration laser pulse.
