Beschreibung
Zusammenfassung:	A method for producing a hollow article made of amorphous metal comprising the steps of: a) providing a metal composition, b) melting the composition according to step a) in order to obtain a melt, c) introducing the melt according to step b) into a cavity of a casting mold, the casting mold comprising an inner core, at least a portion of the lateral surface of the inner core being surrounded by a separation element, d) cooling the melt in the casting mold in order to obtain a molded part made of amorphous metal, e) removing the inner core and the separation element from the molded part according to step d) in order to obtain a hollow article made of amorphous metal. The present invention also relates to a hollow article made of amorphous metal, more particularly to a pipe made of amorphous metal.
