Abstract

This article presents the results of experiments on the impact of powerful pulsed ion-plasma and electron flows generated in the working chamber of the Plasma Focus PF-5M installation during each high-voltage discharge on a model aluminum alloy B95. It is shown that the general characteristics of the alloy’s damage upon exposure to pulsed flows of helium ions (HI) and helium plasma (HP) and pulsed irradiation with electron beams with close values of power density and pulse duration (q = 108–109 W/cm2, τ = 10–30 ns) include the formation of a wavy surface layer of samples containing microcracks, pores, bubbles with destroyed shells, and alloy microdroplets deposited on the irradiated surface. Differences in the alloy’ damageability for the compared radiation-thermal effects are associated with the molten layer significantly greater thickness when the alloy is exposed to an electron beam compared to the action of ion-plasma flows.
