Centrifugal spinning of metallic glass filaments

A new technique for continuous melt spinning of metal filaments in a glassy state has been developed. The technique consists of casting a stream of the melt from an orifice onto a convex inner surface of a rapidly rotating wheel. A number of glass forming alloys, such as transition-semimetals and early transition-transition metals, have been formed successfully into glassy ribbons. The advantages and limitations of this technique will be discussed.
