Process and device for obtaining a wire made of amorphous metal alloy

Method and apparatus (20) for obtaining a wire (12) of amorphous metallic loy, characterized by the fact that a jet (7) of molten amorphizable alloy (4) is contacted with a gas (55) capable of reacting chemically with at least one of the components of the alloy (4) before the jet (7) reaches a cooling liquid (9), so as to form a layer around the jet (7) which is capable of stabilizing it. A distance traversed by the jet (7) between the nozzle and the cooling liquid is greater than 1 cm.

Methods and apparatus for obtaining wires of amorphous metallic alloys

In order to cool the jet coming from a crucible and then the wire as it starts solidifying, there is used a gaseous cooling fluid mixture having a base of gaseous hydrogen and at least one other component which is a compound of hydrogen capable of an endothermic chemical reaction in contact with the jet (wire) and of a chemical composition such that the product or products of this reaction have a high molecular content (mol %) of free hydrogen.
