melt spinning technique (rus. спиннингование) — a method to produce amorphous metal alloys in the form of thin strips by ultra-fast (cooling rate > 106· sec-1) cooling of the melt on the surface of a cold rotating disc or drum.


Amorphous alloys of Fe-Si-B, Fe-Cu-Nb-Si-B and Al-Cr-Ce-M (M = Fe, Co, Ni, Cu) systems serve as a starting material to form nanostructures in them by controlled crystallisation which significantly improves the alloys' mechanical and magnetic properties. Flow turning of the melt occurs when a jet of molten alloy, under excessive gas pressure (the process is conducted in an inert atmosphere) is fed through a hole in the crucible to the surface of a cooled drum rotating at a high speed. The resulting alloy's structure and properties depend on its composition, cooling rate, injection conditions and the difference of temperatures in the crucible and on the drum's surface.
