ABSTRACT: Gas atomization which is a conventional
technique in powder metallurgy is adapted for the formation
of metallic glass nanowires. This approach is able to produce a
large quantity of nanowires with diameters in the 50−2000 nm
range. Experiments performed with different conditions and
alloy compositions confirm that the key mechanism of the
nanowire formation is the spinnability which increases
exponentially when the melt stream is supercooled from the
liquid state.
KEYWORDS: Nanowire, metallic glass, gas atomization, spinnability
