1.\u00a0<\/strong>Introduction aux mat\u00e9riaux GH3044<\/strong>\u00a0<\/strong><\/p>\n

GH3044 alliage \u00e0 haute temp\u00e9rature est un alliage \u00e0 haute temp\u00e9rature de d\u00e9formation renforc\u00e9e solution solide \u00e0 base de Ni-Cr avec une temp\u00e9rature de service inf\u00e9rieure \u00e0 900\u2103. L'alliage contient une grande quantit\u00e9 de tungst\u00e8ne et une petite quantit\u00e9 d'aluminium et de titane. L'alliage a une plasticit\u00e9 \u00e9lev\u00e9e et une r\u00e9sistance thermique moyenne, une excellente r\u00e9sistance \u00e0 l'oxydation et de bonnes performances en mati\u00e8re de processus d'emboutissage et de soudage. Il convient \u00e0 la fabrication de pi\u00e8ces de la chambre de combustion principale et de la chambre de combustion secondaire des moteurs a\u00e9ronautiques qui fonctionnent \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 900\u00b0C pendant une longue p\u00e9riode, ainsi qu'\u00e0 la fabrication d'\u00e9crans d'isolation thermique, d'aubes de guidage, etc. Les principaux produits fournis sont des plaques, des bandes, des soies et des anneaux.<\/p>\n

4. Performance du processus GH3044<\/strong>\u00a0<\/strong><\/p>\n

GH3044 Performance de formage<\/p>\n

GH3044 temp\u00e9rature de chauffage de forgeage de lingot d'acier est 1170\u2103\u00b110\u2103, et la temp\u00e9rature terminale n'est pas inf\u00e9rieure \u00e0 900\u2103. La temp\u00e9rature de chauffage de la plaque de laminage est 1190\u00b110\u2103, la temp\u00e9rature de chauffage de la plaque mince de laminage \u00e0 chaud est 1130\u2103\u00b110\u2103, et la temp\u00e9rature finale de laminage n'est pas inf\u00e9rieure \u00e0 800\u2103 ; le taux de r\u00e9duction de pression totale de la plaque mince de laminage \u00e0 froid est d'environ 30%.<\/p>\n

Les t\u00f4les GH3044 ont de bonnes performances en mati\u00e8re d'emboutissage. Le coefficient de profondeur limite de l'\u00e9tat d'approvisionnement des t\u00f4les minces lamin\u00e9es \u00e0 froid est K limit = 2,06.<\/p>\n

GH3044 Processus de traitement thermique des pi\u00e8ces<\/p>\n

La temp\u00e9rature de traitement thermique interm\u00e9diaire est de 1140\u2103\u00b110\u2103, isolation pendant 3~5 minutes, refroidissement \u00e0 l'air. La temp\u00e9rature finale de traitement thermique est d\u00e9termin\u00e9e en fonction des conditions de travail des pi\u00e8ces. Les pi\u00e8ces avec une bonne performance de fatigue thermique sont en solution solide \u00e0 1150\u2103, et l'isolation est de 3~5 minutes, et l'isolation est refroidie \u00e0 l'air ; les pi\u00e8ces avec une force de chaleur \u00e9lev\u00e9e sont en solution solide \u00e0 1200\u2103, et l'isolation est de 3~5 minutes, et l'isolation est refroidie \u00e0 l'air.<\/p>\n

V. Champs d'application du GH3044<\/strong>\u00a0<\/strong><\/p>\n

Convient \u00e0 la fabrication de pi\u00e8ces devant r\u00e9sister \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es, ainsi qu'aux \u00e9crans d'isolation thermique, aux lames de guidage et \u00e0 d'autres pi\u00e8ces devant fonctionner \u00e0 moins de 900\u00b0C pendant une longue p\u00e9riode.<\/p>","protected":false},"excerpt":{"rendered":"
