Surface oxidation of FeSiB amorphous alloy and its effect on metallic glass fiber reinforced cement mortar.

ABSTRACT: Amorphous alloys and metallic glass fibers have superior properties for both structural and functional applications. In this study, Fe₇₈Si₉B₁₃ amorphous alloys were annealed in air at 25-400 °C for 0-60 min to introduce surface oxidation. Pristine fibers with a volume content of 0, 0.25, 0.5, 0.75, 1, 1.25 and 1.5 vol% and surface-oxidized fibers with a content of 0.5 vol% were used to prepare fiber reinforced cement mortars. Structural, thermal, magnetic and mechanical properties were characterized for pristine fibers, oxidized fibers and mortar specimens. Air-annealed alloys remain amorphous and produce a partially oxidized surface, which reduces saturation magnetization. Mortars reinforced by pristine fibers exhibit 6.4% and 32.4% of increase in compress
