Structure and properties of the composite materials consisting of the nanocrystalline Fe73.5Cu1Nb3Si13.5B9 alloy powders and polyethylene

This paper presents the material and technological solution which makes it possible obtaining of the nanocrystalline, ferromagnetic powder material of Fe73.5Cu1Nb3Si13.5B9 alloy after its thermal nanocrystallization with its succeeding high-energy milling. Another aspect was developing the technology to obtain the nanocrystalline composites made by binding the obtained powder material with the high density pressureless polyethylene (PEHD) with the controlled ferromagnetic and mechanical properties. The module for their forming has been designed. The module consists of the die enclosed in the heater-coupled testing machine set up for compression test. It was possible, with the stand set up like that to compact the fabricated components (one-sided uniaxial pressing). The high density pressureless polyethylene powder was used as binder with mass fraction of 2.5, 5.0, and 7.5%.
