1. Introduction du mat\u00e9riau Inconel718<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 L'alliage Inconel718 est un alliage pr\u00e9cipit\u00e9 de nickel-ferrochrome durci contenant du niobium et du molybd\u00e8ne. Il pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e, une bonne t\u00e9nacit\u00e9 et une bonne r\u00e9sistance \u00e0 la corrosion \u00e0 des temp\u00e9ratures inf\u00e9rieures \u00e0 650\u00b0C. L'\u00e9tat peut \u00eatre un traitement en solution solide ou un \u00e9tat de durcissement par pr\u00e9cipitation.<\/span><\/p>\n

IV. Caract\u00e9ristiques du mat\u00e9riau Inconel718<\/span><\/strong><\/p>\n

    \n
  • Facile \u00e0 traiter<\/span><\/li>\n
  • Il pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la traction, \u00e0 la fatigue, au fluage et \u00e0 la rupture \u00e0 700\u00b0C.<\/span><\/li>\n
  • Haute r\u00e9sistance \u00e0 l'oxydation \u00e0 1000\u00b0C<\/span><\/li>\n
  • Propri\u00e9t\u00e9s chimiques stables \u00e0 basse temp\u00e9rature<\/span><\/li>\n
  • Bonne performance de soudage<\/span><\/li>\n<\/ul>\n

    5. Structure m\u00e9tallographique de l'Inconel718<\/span><\/strong><\/p>\n

    L'alliage GH4169 a une structure aust\u00e9nitique, et la phase \u03b3 g\u00e9n\u00e9r\u00e9e apr\u00e8s pr\u00e9cipitation et durcissement lui conf\u00e8re d'excellentes propri\u00e9t\u00e9s m\u00e9caniques. La phase \u03b4 g\u00e9n\u00e9r\u00e9e au niveau du joint de grain pendant le traitement thermique lui conf\u00e8re la meilleure plasticit\u00e9.<\/span><\/p>\n

    6. R\u00e9sistance \u00e0 la corrosion de l'Inconel718<\/span><\/strong><\/p>\n

    L'alliage Inconel718 pr\u00e9sente une excellente r\u00e9sistance \u00e0 la corrosion fissurante et aux piq\u00fbres, ind\u00e9pendamment de l'environnement \u00e0 haute ou basse temp\u00e9rature. L'alliage Inconel718 pr\u00e9sente une excellente r\u00e9sistance \u00e0 l'oxydation \u00e0 haute temp\u00e9rature.<\/span><\/p>\n

    7. Domaines d'application<\/span><\/strong><\/p>\n

    En raison de sa r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, de son excellente r\u00e9sistance \u00e0 la corrosion et de sa facilit\u00e9 de traitement \u00e0 700\u00b0C, il peut \u00eatre largement utilis\u00e9 dans diverses situations de forte demande.<\/span><\/p>\n
