Prokhorenko I. Physical and technological basis of performance testing of materials and energy industry equipment

The dissertation deals with scientific and technical problem of change testing of the structure of materials. These materials are used in power equipment. Various test methods are used. As a test, a beam of accelerated electrons was used. Results were obtained for aluminum alloys of the 6111 series, aluminum alloys 2014, granite breeds. A model was proposed for the calculation of displacement fields for hexagonal and cubic crystals. The dependence of displacement fields on the shape of the defect was considered. Materials which can be the receivers of detectors of ionizing radiation were studied. These materials contain a mercury. The methods of infrared radiometry were used for study of the structure of materials of high-voltage and caldron equipment of Zmievskaya TPP, and also systems of water cooling of Zaporozhskay NPP. Finished off the system of individual thermal protection. The technology of production of polystyrene-metallic radiation-protective materials has been developed. For the first time it has been proposed to produce a composite material in the form of balls. This increases its mobility. The production of composite materials was performed on an already existent equipment. The equipment was slightly improved. The mechanical and radiation-protective characteristics of these materials are determined.
