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 highvoltage
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
