The Effect of High-Power Pulsed Flows of High-Temperature Plasma on the Structure of Aluminum Alloys

In this final qualifying work, the description of the device of the gas-discharge type Plasma focus (PF) is analyzed in detail. The main directions for the use of this object are: a) research in the field of fundamental physics of plasma, including tightly magnetized; b) the source of a wide range of radiation (nanosecond pulses of hard and soft x-ray, neutron radiation, as well as fast ions and electron flows used for applied research in radiation materials science, as for dynamic quality control); с) tuition of young scientists in vacuum methods, plasma physics and its diagnostics, neutron and x-ray spectroscopy, as well as in the above-mentioned applications of a nanosecond density source based on hard radiation in a PF-type facility. In this work, in addition to an extensive literary review, I made in last year's interdisciplinary course work, describes an experiment with ceramic samples based on Al2O3 (supplemented over the past year by profilometric, x-ray phase studies and numerical methods), as well as the study of damage and structural state of the surface layer of aluminum alloy samples of Al-Mg-Li system of Al-5% Mg-2% Li (wt.% ) under the pulsed action of high-power flows of high-temperature deuterium plasma and high-energy deuterium ions in the Plasma focus unit, recently conducted in the above-mentioned areas, together with the results obtained and the discussion of the plasma diagnostics specifics in relation to Plasma focus-type units.
