1. Introduction \u00e0 la\u00a0<\/span><\/strong>GH5188\u00a0<\/span><\/strong>Mat\u00e9riaux<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0GH5188 est un alliage haute temp\u00e9rature \u00e0 d\u00e9formation renforc\u00e9e par solution solide \u00e0 base de Co-Ni-Cr avec une temp\u00e9rature d'utilisation inf\u00e9rieure \u00e0 1100\u2103. Ajouter 14% w(W) \u00e0 l'alliage pour le renforcement de la solution solide, de sorte que l'alliage a une bonne performance globale ; ajouter une teneur plus \u00e9lev\u00e9e en chrome et trace de lanthane pour rendre l'alliage a une bonne r\u00e9sistance \u00e0 l'oxydation \u00e0 haute temp\u00e9rature. L'alliage a de bonnes propri\u00e9t\u00e9s de traitement telles que la plasticit\u00e9 de traitement \u00e0 chaud et \u00e0 froid et le soudage, et convient \u00e0 la fabrication de pi\u00e8ces de moteur d'avion qui n\u00e9cessitent une r\u00e9sistance \u00e9lev\u00e9e inf\u00e9rieure \u00e0 980\u2103 et n\u00e9cessitent une r\u00e9sistance \u00e0 l'oxydation inf\u00e9rieure \u00e0 1100\u2103.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0GH5188 peut produire et fournir divers produits de d\u00e9formation, tels que des t\u00f4les minces, des t\u00f4les moyennes, des bandes, des barres, des pi\u00e8ces forg\u00e9es, des mat\u00e9riaux en soie et des pi\u00e8ces moul\u00e9es de pr\u00e9cision.<\/span><\/p>\n
