Melt Spinning of Metals
Melt spinning is one way to make amorphous metals or "metglas". It always produces thin (around 50 µm) and very long (many m) ribbons (some mm - several cm in width) of the stuff. In essence, the metal retains more or less its liquid and thus amorphous structure because it is cooled down with extreme speed - around 1.000.000 °C/s (1.800.000 °F/s) - making atom movement in the
