Abstract
The role of B and Si in the formation of (FeCoCrNi) 100-x-y B x Si y high-entropy metallic glasses is studied. It is found that a content of B between 10 and 20 at% and of Si between 5 and 15 at% is able to produce a completely amorphous structure. The microstructural evolution of two of this high-entropy metallic glass compositions, (FeCoCrNi) 80 B 20 and (FeCoCrNi) 80 B 10 Si 10 , have been studied by X-ray diffraction and Transmission Mössbauer Spectroscopy. In both compositions, the first c...
