Ivanov V. Development of theoretical bases of technological parametersimpact on the structure and properties of gray cast iron castings

The thesis is devoted to the further development of the theoretical foundations of the cast iron casting structure depending on the melting conditions, crystallization, molten mass cooling and processing, establishing the patterns of formation of suboxide compounds and their impact on the graphite phase formation and properties of cast products. Technological parameters control schemes for cast iron have been developed to provide the given graphite phase morphology and high performance properties of cast iron castings. A complex research technique of graphite inclusions formation using the petrographic method in combination with other modern methods was implemented and used. The use of the obtained results made it possible to improve the technological parameters of cast iron castings production and to ensure their high operational properties.
