Usenko B. Thermophysical peculiarities of structure formation of metals at their solidification

object - technologies of formation an amorphous structure of metal; goal - research of thermophysical peculiarities of structure formation of metals at their solidification; methods - experimental, theoretical, mathematical modeling, experiment planning, a comparative analysis of the data; theoretical and practical results - developed a method for predicting the degree of amorphization of metals and alloys under given of technological modes processing of details; developed methodical recommendations for the implementation of the research technologies; developed a device for the formation of massive amorphous structures by the method of casting in the copper form with fast cooling; developed mathematical models processes of obtaining amorphous structure, based on the mathematical models developed methodology determination of optimum technological modes producing amorphous structures; identified complex effect of thermophysical parameters and ultrasonic on process of formation an amorphous structure; identified the main thermophysical and technological peculiarities technologies of formation of massive amorphous structures for a wide variety of metals by using different technologies and theoretically proved the dependence of thermophysical characteristics on the parameters of appropriate technologies; novelty - justified and formulated a comprehensive approach to create conditions amorphization of metals, which allowed to identify the main thermophysical parameters of this process for a wide variety of metals when processing different technologies; for the first time based on the experimental research created mathematical relationships, which allows to calculate the basic technological parameters creation of amorphous structures of different metals; have been further developed the scientific foundations developing rational technologies the predicted amorphization of metals, thereby creating the appropriate forecasting methodology energy parameters of appropriate technologies; have been further developed technological bases formation of amorphous structures of various metals and alloys, which allowed to find a rational relations of operating parameters technologies of amorphization; the degree of implementation - the main results are implemented with the modernization of equipment for surfacing and technology of forming the surface layer of the metal with an amorphous structure when surfacing with forced cooling surface; sector (industry) application - the sphere of power mechanical engineering, thermal power industry.
