Download or read book Contribution l tude des transformations des alliages binaires or nickel et ternaires or nickel cuivre written by Térésa Toll-Duchanoy and published by . This book was released on 1976 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les alliages binaires or-nickel et ternaires or-nickel-cuivre, contenant 54 at. % d'or, se décomposent à la température de 460°C par un processus de germination et croissance. Ces alliages se trouvent donc à l'extérieur de la spinodale cohérente du diagramme d'équilibre. La substitution partielle de cuivre se traduit par : un ralentissement considérable de la cinétique de décomposition de la solution solide, un rétrécissement et un déplacement de la lacune de miscibilité vers les fortes teneurs en nickel, un accroissement du paramètre cristallin de la solution solide stable a haute température. Ce comportement peut s'expliquer à partir des interactions attractives entre les atomes d'or et de cuivre.

This book was released on 1972 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Nous avons rassemblé, dans le chapitre I de notre mémoire, les différentes méthodes expérimentales utilisées, et exposé les résultats que ces dernières sont susceptibles de fournir. Au chapitre II, après un bref rappel bibliographique, nous présentons une étude, par microscopie optique et électronique, des transformations structurales dans les alliages binaires fer-nickel puis nous déterminons les relations d'orientation entre les phases. Le chapitre III est consacré à une étude cinétique de la formation de l'austénite à partir d'une structure trempée et à l'interprétation des mécanismes de transformation. Les deux dernières parties traitent des alliages ternaires fer-nickel-molybdène. Au chapitre IV, nous reprenons une étude cinétique parallèle à celle que nous avions effectuée sur le binaire. Les processus de la formation de l'austénite et des précipitation des phases riches en molybdène ont pu être spérarés, ce qui a permis de les analyser. Enfin, nous précisons l'influence de teneurs variées en nickel et en molybdène sur les différentes structures. Afin d'expliquer certains résultats, nous avons fait appel, dans le dernier chapitre, à la mesure de l'intensité des rayons X diffusés et à la spectrométrie Mössbauer. Ces techniques nous ont permis de proposer un modèle atomique relatif au mécansime de formation des précipités, au cours du traitement de "maraging"."
