Experiments on the influence of high-temperature plasma nanosecond pulse ra
diation, as generated in plasma focus device, on the W-Cu pseudoalloy, V-35
at%Ti alloy, austenitic chromium-manganese 10Cr12Mn20W and 25Cr12Mn20W stee
ls have been carried out. Features of damages, phase-structural transformat
ions and chemical content changes in those materials under such irradiation
were investigated.
