SEM micrographs.
(a) As-received Zr-based metallic glass fibers fabricated by gas atomization. (b) Mechanically milled mixture of Al7075 powders and glass fibers and (c) mechanically milled mixture of Al7075 powders and glass fibers in higher magnification (bright areas correspond to the glassy phase, dark areas correspond to the Al7075 alloy).
