Реферат: Composites consisting of Fe66Cr10Nb5B19 alloy particles and a copper matrix were obtained by spark plasma sintering (SPS) at 700 and 800 ◦C. As copper does not form compounds with any of the alloy components, it can be considered as an inert matrix. The initial state of the Fe66Cr10Nb5B19 alloy was glassy. During SPS of Cu–40 vol % Fe66Cr10Nb5B19, densification was complete at 630 ◦C. As the sample was not fully dense upon reaching the glass transition temperature of the alloy (521 ◦C), the metallic glass particles changed their morphology and surface topography to fill the pore space, which was enabled by the viscous flow of the supercooled liquid. Fracture of the sintered composites occurred along the Cu/Fe66Cr10Nb5B19 interface and through the contacts between the Fe66Cr10Nb5B19 particles.
