For the commercialization of scientific development it is necessary to represent at what level of readiness for implementation it is. Of particular importance is the evaluation of the level of readiness of development (PEM) acquired in the implementation of large-scale costly projects, for example, in the space or military industry. The experience of using the TRL assessment method confirms that it is an effective tool for the development of technologies, facilitating risk management, making optimal decisions regarding the financing of technologies and their transfer. Today, the use of the method of assessing the levels of readiness has become mandatory in deciding whether to finance projects for the development and transfer of technologies in various international programs. It should also be considered as one of the tools needed to manage the progress of research and development in organizations that develop new technologies. 2017-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/143737 Трансформация структуры высокоуглеродистого сплава Fe-V-C при обезуглероживании Мовчан, А.В.; Губенко, С.И.; Черноиваненко, Е.А. The regularities of phase and structural transformations during decarburization of a highcarbon Fe-V-C alloy were investigated. The eutectic transformation L → γ + VC is established by the method of geometric thermodynamics and metallographic analysis. That accompanied by a diffuse redistribution of the carbide-forming element ahead of the crystallization front. Decarburization in a liquid-solid state allows forming a favorable structure with VC fibers oriented perpendicular to the surface in the near-surface zone. It was established that the subsequent carburization of a pre-decarburized Fe-V-C alloy under special conditions makes it possible to obtain in the surface layer a natural composite with high wear resistance. 2017-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/143736 Влияние пластической деформации на структуру и свойства газаров Карпов, В.Ю.; Губенко, С.И.; Карпов, В.В. It is determined that the mechanical properties of gazars depend on the degree and method of their deformation, changes in the porous structure. It is established that during rolling, the change in the strength properties of gazars occurs more intensively than when drawing by 25-40%. It is shown that the surface porous layers of gazars are intensively deformed, become practically monolithic and receive a high level of hard work, which sharply increases their strength. It is proved that deformed but not annealed samples have a strength of 2 ... 3 above higher than monolithic samples of the same dimensions. After annealing, the strength of gazars is 1.5 ... 2 above higher. The process of changing the structure of gazars after annealing for removing internal stresses is considered. Possible mechanisms for changing the porous structure of gazars and increasing their strength are proposed. 2017-01-01T00:00:00Z
