Title

(FR) FIBRES ET VERRES MÉTALLIQUES MICROMÉTRIQUES ET NANOMÉTRIQUES ULTRALONGS À STRUCTURE COMPLEXE
Abstract
(EN)
The present invention and its embodiments propose a simple, unique, and scalable method for producing extremely long, highly uniform, and well-ordered micro- and nanoscale metallic glasses via thermal drawing the method comprising at least the steps of preparing a macroscopic scale first preform assembled from compatible materials for co-drawing such as a metallic glass structure encased in a supporting first cladding made of a polymer or glass; thermally drawing the first preform into a first fiber.
(FR)
La présente invention et ses modes de réalisation concernent un procédé simple, unique et évolutif permettant de produire des verres métalliques micrométriques et nanométriques extrêmement longs, très uniformes et bien ordonnés par étirage thermique, le procédé comprenant au moins les étapes consistant à préparer une première préforme à échelle macroscopique assemblée à partir de matériaux compatibles pour le coétirage tels qu'une structure de verre métallique enfermée dans une première gaine de support constituée d'un polymère ou d'un verre; à étirer thermiquement la première préforme pour obtenir une première fibre.
