Structure and Properties of a Ribbon from FeCoNiSiB High-Entropy Alloy

Using the methods of advanced physical materials science, the structural-phase states and properties of an ~80 μm-thick ribbon, made from a FeCoNiSiB high-entropy alloy of a non-equiatomic composition by ultrarapid quenching from melt, are studied. After the melt spinning the ribbon is in an X-ray amorphous state and demonstrates high strength and low plasticity. Anisotropy of its tribological properties is revealed. A differential scanning calorimetry of the ribbon is performed and its magnetic properties are evaluated.
