气体雾化是粉末冶金中的传统技术，适用于金属玻璃纳米线的形成。这种方法能够生产大量直径在 50-2000 nm 范围内的纳米线。在不同条件和合金成分下进行的实验证实，纳米线形成的关键机制是可纺性，当熔体流从液态过冷时，可纺性呈指数增加。
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.
