The composition, structure, properties and technology for producing the dispersion strengthened composite material of Al–Si–Ni–Fe–Al2O3–C–O system for the high performance internal combustion engine pistons were proposed. The prepared material depending on the chemical composition has a tensile strength from 600 to 650 MPa at normal temperature with a relative elongation of 1,7 to 2,5 % and 180...195 MPa at a test temperature of 350 °C. The coefficient of linear thermal expansion in a temperature test range of 20...150 °C is equal to (16,8...17,4)·10-6 1/°C and at a temperature test range of 20...350 °C - (18,9...19,5)·10⁻⁶ 1/°C. 2016-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/143718 Управление процессами контактного взаимодействия при пропитке макрогетерогенных композиционных материалов на основе железа Суховая, Е.В.; Сыроватко, Ю.В. The phase and structural composition of the interfacial zones between the W–C filler and the Fe–C–B–P–Mo matrix of the composite materials was investigated by quantitative metallographic, X-ray, energy dispersive X-ray, and statistical methods. The peculiarities of a structure formation of the interfaces of dissolution-and-diffusion type were explained based on the regular solution formality taking into account that ion Mo creating non-uniformly charged ion cloud around itself are considered as a local disturbance. The ways to control the intension of the interfacial reactions between the filler and the molten binder under infiltration of composite materials have been recommended. 2016-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/143717 Влияние скорости нагрева в процессе искро-плазменного спекания на кинетику уплотнения, структурообразование и свойства материалов системы Fe–Ti–C–(B) Присташ, Н.С.; Сизоненко, О.Н.; Зайченко, А.Д. Experimental data about impact of heating rate in range from 10 up to 20 °C/s under spark plasma sintering on grain size, structure and mechanical properties of Fe–Ti–C–(B) carbide steels system is given. It was established, that increasing heating rate up to 20 °C/s in consolidation mode with holding temperature of 1100 °􀉋 during 180 seconds leads to decrease of mean iron grain size in material structure from ~3.5 to ~2 􀈝m and allows to obtain Fe–Ti–C–(B) carbide steels system with hardness of 70 HRC and wear-resistance seven times higher than of tungsten-containing HSS M2 steel. 2016-01-01T00:00:00Z
