Investigation of vanadium alloys in CTR plasma disruption-simulation experiments
The experimental results of vanadium-based alloys behavior in CTR plasma disruption-simulation experiments have been presented. The samples have been irradiated by high temperature pulsed deuterium plasma fluxes (HTPPF) in an accelerator type MK-200. The flux specific power Q has been (0.5, 2.0, and...

| description | The experimental results of vanadium-based alloys behavior in CTR plasma disruption-simulation experiments have been presented. The samples have been irradiated by high temperature pulsed deuterium plasma fluxes (HTPPF) in an accelerator type MK-200. The flux specific power
Q has been (0.5, 2.0, and 10) × 10
10 W/m
2, impulse duration τ about 50 μs, 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 irradiation results in topography changes and material erosion caused by their intensive heat, melting, and evaporation. The mass loss changes from 1.6 to 32 μg/J and depends on irradiation regime (
Q) and material type. Hard action results in cracking of materials caused by thermal stresses. |
