Abstract
A process and apparatus is provided whereby filaments of metals may be formed by rapid solidification of a molten jet in a fluid medium. Filaments of metastable alloys such as amorphous metals and filaments of fine grained structure having novel orientation may be obtained.
Claims2
A filament consisting essentially of hexagonal close-packed metals and alloys thereof wherein the <001>
- axes are oriented at an angle greater than 60.degree. to the filament axis said filament produced by a process which comprises the steps of
- a. melting material comprising hexagonal close-packed metals or alloys thereof;
- b. extruding a molten filament of the molten material;
- c. passing said molten filament in sequence (1) through a controlled gaseous interface zone and (2) into a liquid quench zone, said quench zone comprising a liquid medium which is flowing cocurrently with and essentially as the same velocity as the filament introduced therein;
- and
- d. recovering the solidified filament.
