Public ISBD [article]  inActa materialia > Vol. 58 N° 4 (Fevrier 2010) . - pp. 1299–1308 Titre : Characterization and properties of an advanced composite substrate for YBCO-coated conductors Type de document : texte imprimé Auteurs : Mangmang Gao, Auteur ; Hongli Suo, Auteur ; Yue Zhao, Auteur Année de publication : 2011 Article en page(s) : pp. 1299–1308 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Composite substrate Coated conductors Cubic texture In situ EBSD tensile test Texture stability Résumé : Thin, biaxially textured Ni5W/Ni12W/Ni5W composite substrates for coated conductor applications have been fabricated. The particularity of this three-layer composite configuration resides in the elemental diffusion between the outer layer and the core layer. Due to the migration of elemental W, the diffusion layer in the as-annealed substrate becomes broader than that of the as-rolled substrate. The obtained tape has a sharp cubic texture on the Ni5W outer layers, and the volume fraction of cubic grains exceeds 98.8% ( DEWEY : 669 ISSN : 1359-6454 En ligne : http://www.sciencedirect.com/science/article/pii/S1359645409007289 [article] Characterization and properties of an advanced composite substrate for YBCO-coated conductors [texte imprimé] / Mangmang Gao, Auteur ; Hongli Suo, Auteur ; Yue Zhao, Auteur . - 2011 . - pp. 1299–1308.
