amorphous ribbon

amorphous ribbon

[ə′mȯr·fəs ′rib·ən]
(metallurgy)
A metallic alloy that has an amorphous structure and is formed into a strip 25 to 50 micrometers thick and 1 to 150 millimeters (0.04 to 6 inches) wide by a process in which a melt of the required composition is ejected through an orifice onto a copper drum where it is instantly quenched and formed into a ribbon by rotation of the drum.

95% purity and amorphous ribbon 6 mm wide and about 20 [micro]m thick was produced by planar flow casting technique in vacuum at the Institute of Physics, Slovak Academy of Sciences in Bratislava.
Nanocrystalline soft magnetic alloys prepared by devitrification of melt-spun amorphous ribbons are interesting because of their magnetic properties superior to previously used materials, offering large inductions and good temperature stability.
Other possible morphologies include fibrous structures, platelets, amorphous ribbons, and even dual-phase interpenetrating blends, created by drawing one layer of material through holes in another layer and tacking the two together.
