The experimental results of vanadium-based alloys behavior in CTR plas
ma disruption-simulation experiments have been presented. The samples
have been irradiated by high temperature pulsed deuterium plasma fluxe
s (HTPPF) in an accelerator type MK-200. The flux specific power Q has
been (0.5, 2.0, and 10) x 10(10) W/m(2), impulse duration tau about 5
0 mu s, and the number of impact impulses N = 5 and 30, respectively.
The radiation erosion, material topography changes, structure, element
and phase quality content, and face hardening have been investigated.
It has been shown that for all the investigated alloys HTPPF irradiat
ion results in topography changes and material erosion caused by their
intensive heal, melting, and evaporation. The mass loss changes from
1.6 to 32 mu g/J and depends on irradiation regime (Q) and material ty
pe. Hard action results in cracking of materials caused by thermal str
esses.
