1. Introduction aux mat\u00e9riaux 4J36<\/span><\/p>\n

Le 4J36 est un alliage sp\u00e9cial de fer-nickel \u00e0 faible dilatation avec un coefficient de dilatation tr\u00e8s bas. Parmi eux, le contr\u00f4le des composants de carbone et de mangan\u00e8se est tr\u00e8s important. La d\u00e9formation \u00e0 froid peut r\u00e9duire le coefficient de dilatation thermique, et le traitement thermique dans une plage de temp\u00e9rature sp\u00e9cifique peut stabiliser le coefficient de dilatation thermique. Le 4J36 est r\u00e9sistant \u00e0 la corrosion dans l'air sec \u00e0 temp\u00e9rature ambiante. Dans d'autres environnements difficiles, tels que l'air humide, la corrosion (rouille) peut se produire.<\/span><\/p>\n

4J36 Alliage expans\u00e9 Aper\u00e7u Le point de Curie de l'alliage expans\u00e9 4J36 est d'environ 230\u2103. En dessous de cette temp\u00e9rature, l'alliage est ferromagn\u00e9tique et son coefficient de dilatation est tr\u00e8s faible. Au-dessus de cette temp\u00e9rature, l'alliage est amagn\u00e9tique et le coefficient d'expansion augmente. Cet alliage est principalement utilis\u00e9 pour fabriquer des composants dont les dimensions sont \u00e0 peu pr\u00e8s constantes dans la plage de variation de temp\u00e9rature, et il est largement utilis\u00e9 dans l'industrie radio, les instruments de pr\u00e9cision, l'instrumentation et d'autres industries. 4J36 Cet alliage est un alliage typique \u00e0 faible dilatation. Il est utilis\u00e9 depuis longtemps dans les usines d'aviation et ses performances sont stables. Pendant l'utilisation, le processus de traitement thermique et le processus de traitement doivent \u00eatre strictement contr\u00f4l\u00e9s pour garantir la stabilit\u00e9 du mat\u00e9riau.<\/span><\/p>\n
