The paper describes the peculiarities of the formation of the medium-grained low-cobalt WC—6Co cemented carbide at temperatures of 1300, 1350, 1400, 1450, 1470, 1500, 1530, 1550, and 1750 °C which permit formulating the principles of serial production of two-phase WC—Co cemented carbides having optimal carbon – free structure. 2010-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/24261 Влияние хрома на контактное взаимодействие сплавов системы Fe–Al с графитом при нагреве под высоким давлением Боримский, А.И.; Делеви, В.Г.; Нагорный, П.А.; Боримский, И.А.; Чипенко, Т.Ю.; Соболев, В.Б. The effect has been studied of chromium added to the composition of Fe–Al alloys on the microstructure of the contact melting region, which forms in the interaction of Fe–Al alloys with graphite at 5 GPa and 1600 K. It has been found that the microstructure of the contact melting region corresponds to the horizontal section of the Fe–C metastable phase diagram. Fe3C carbide that forms in the region of the contact melting of alloys of the Fe–Al system is shown to be unstable and with Al concentration above 4 mass % decomposes partially. An addition of chromium to the composition of Fe–Al alloys does not change the structure and phase composition of the contact melting region but increases the Fe3C carbide stability suppressing the carbide decomposition. 2010-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/23482 Исследование возможности использования инструмента с алмазным волокном в рабочем слое для обработки некоторых видов горных пород Сидорко, В.И.; Курилович, В.Д.; Пегловский, В.В. In article possibility of use of the tool a working layer is considered, which is made of a diamond fibre for different kinds of a stone 2010-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/23481 Експериментальне дослідження параметрів технологічної системи ВПІД та робочих режимів п’ятипозиційного каменеобробного фрезерного верстату з ЧПК Чемоданов, П.А.; Сідорко, В.І. The coefficients of inflexibility of machine-tool are certain in three directions of the threedimensional system of co-ordinates (х,y,z) depending on the chart of loading and dependences of the productivity of process of the diamond polishing (milling at treatment of marble and granit flag) are experimentally certain on the parameters of process of treatment. 2010-01-01T00:00:00Z
