1. Introduction aux mat\u00e9riaux 1J85<\/span><\/p>\n

1J85 Le m\u00e9tal \u00e0 base de nickel est un alliage magn\u00e9tique doux, \u00e9galement connu sous le nom de permalliage. Il poss\u00e8de une susceptibilit\u00e9 magn\u00e9tique tr\u00e8s \u00e9lev\u00e9e et peut \u00eatre magn\u00e9tis\u00e9 dans un champ magn\u00e9tique plus faible et obtenir une force d'induction magn\u00e9tique plus \u00e9lev\u00e9e. Il peut \u00e9galement atteindre rapidement la saturation. C'est un meilleur ferromagn\u00e9tique lorsque la temp\u00e9rature de Curie est inf\u00e9rieure \u00e0 400\u2103. L'alliage \u00e0 base de nickel 1J85 a une perm\u00e9abilit\u00e9 magn\u00e9tique de d\u00e9part \u00e9lev\u00e9e, une force coercitive relativement faible et une perm\u00e9abilit\u00e9 magn\u00e9tique maximale \u00e9lev\u00e9e. Il r\u00e9agit de mani\u00e8re tr\u00e8s sensible \u00e0 certains signaux faibles et pr\u00e9sente un grand potentiel d'application dans l'industrie des t\u00e9l\u00e9communications et l'industrie de l'instrumentation. Parall\u00e8lement, l'alliage \u00e0 base de nickel 1J85 est \u00e9galement facile \u00e0 transformer en une bande m\u00e9tallique tr\u00e8s fine, qui peut \u00eatre utilis\u00e9e dans les selfs \u00e0 haute sensibilit\u00e9, les transformateurs audio, les amplificateurs magn\u00e9tiques rapides, les relais, les boucliers magn\u00e9tiques, divers noyaux de fer, etc. et constitue un composant de l'industrie de la d\u00e9fense, comme l'a\u00e9rospatiale et l'industrie nucl\u00e9aire.<\/span><\/p>\n

IV. Caract\u00e9ristiques du mat\u00e9riau 1J85<\/span><\/p>\n

L'alliage fer-nickel 1J85 est un alliage de nickel contenant 79-81% avec la perm\u00e9abilit\u00e9 magn\u00e9tique initiale la plus \u00e9lev\u00e9e, la perm\u00e9abilit\u00e9 magn\u00e9tique maximale et une coercivit\u00e9 extr\u00eamement faible, qui est sensible aux signaux faibles. La force d'induction magn\u00e9tique satur\u00e9e du 1J85 est sup\u00e9rieure \u00e0 0,78T, la perm\u00e9abilit\u00e9 magn\u00e9tique initiale est sup\u00e9rieure \u00e0 30mH\/m, la perm\u00e9abilit\u00e9 magn\u00e9tique maximale est sup\u00e9rieure \u00e0 115mH\/m et la force coercitive est inf\u00e9rieure \u00e0 2,4A\/m.<\/span><\/p>\n

Structure m\u00e9tallographique de 1J85 : L'alliage 1J85 a une structure aust\u00e9nitique.<\/span><\/p>\n

L'acier alli\u00e9 aust\u00e9nitique est un cristal dont les atomes internes sont dispos\u00e9s selon certaines r\u00e8gles. Il existe g\u00e9n\u00e9ralement trois m\u00e9thodes d'agencement : la structure de r\u00e9seau cubique au centre du corps et la structure polycristalline, qui se forme au cours du processus de cristallisation du m\u00e9tal.<\/span><\/p>\n
