Abstract

The influence of partial replacement of Fe by Ni in (_{Fe1-x Nix}) 71 Nb6 B23 (0≤x≤0.5) bulk glassy alloys on the enhancement of the plasticity has been investigated. The increase of the Ni-to-Fe concentration ratio effectively improves the compressive plasticity. The (Fe0.5 Ni0.5) 71 Nb6 B23 alloy exhibits an enhanced plastic strain of ∼4.2%, together with high strength and distinct strain hardeninglike characteristics, when compared with the Ni-free Fe71 Nb6 B23 glass. The improved mechanical properties are ascribed to the control of the intrinsic elastic properties, followed by favorably tuning the interatomic interaction.
