Brazing copper to alumina using reactive CuAgTi alloys / O. Kozlova in Acta materialia, Vol. 58 N° 4 (Fevrier 2010) 

Public ISBD [article]  in Acta materialia > Vol. 58 N° 4 (Fevrier 2010) . - pp. 1252–1260 Titre : Brazing copper to alumina using reactive CuAgTi alloys Type de document : texte imprimé Auteurs : O. Kozlova, Auteur ; M. Braccini, Auteur ; R. Voytovych, Auteur Année de publication : 2011 Article en page(s) : pp. 1252–1260 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Brazing  Joining  Interfaces  Mechanical  properties  Alumina Résumé : The purpose of this work was to describe and discuss the fundamental issues involved in reactive brazing of alumina to copper by CuAgTi alloys. The method used to bring the Ti to the CuAg braze enabled the Ti concentration in the braze to be varied to a large extent (from 0.8 to 6 wt.%). It was then possible to study the effects of this parameter on the interfacial chemistry and joint microstructure, as well as on the mechanical performance of the brazing joints, characterized by tensile tests. The mechanical strength of metal/alumina joints processed by reactive brazing was also compared with data obtained using a standard metallization process.
