He nickel alloy ikaika kiʻekiʻe ʻo INCONEL 718, kūpaʻa i ka pala. Hana nui ʻia ia me ka nickel, me ka nui o ka chromium, ka hao, a me nā mea liʻiliʻi ʻē aʻe e like me ka molybdenum, niobium, a me ka alumini. Ua kaulana ka alloy no kona mau waiwai mechanical maikaʻi loa, me ke kiʻekiʻe o ka tensile, ka yield, a me ka luhi, a me ka paʻakikī maikaʻi a me ke kūʻē ʻana i ka haki a me ka deformation creep. Hōʻike pū ʻo INCONEL 718 i ke kūʻē kūikawā i ka pala, ʻoiai ma nā mahana kiʻekiʻe, e kūpono ai no ka hoʻohana ʻana i nā wahi hoʻouka kaua e like me ka aerospace, ka hana kemika, a me nā noi moana. Hoʻohana pinepine ʻia ia i ka hana ʻana i nā ʻāpana turbine kinoea, nā mīkini rocket, a me nā ʻāpana like ʻole i kau ʻia i ke kaumaha kiʻekiʻe a me nā kūlana koʻikoʻi.
He superalloy nickel-based ʻo INCONEL 718 i ʻike ʻia no kona mau waiwai mechanical kūikawā i nā mahana kiʻekiʻe. Hana nui ʻia ia me ka nickel, me nā liʻiliʻi o nā mea ʻē aʻe e like me chromium, hao, niobium, molybdenum, a me ka alumini. Hāʻawi ʻo INCONEL 718 i ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi i ka palaho, a me ke kūpaʻa oxidation maikaʻi loa, e kūpono ai no ka hoʻohana ʻana i nā wahi koʻikoʻi e like me nā mīkini aerospace a me nā mīkini turbine kinoea. Hoʻohana pinepine ʻia ia i nā noi e pono ai ke kūpaʻa wela kiʻekiʻe, e like me nā mea hoʻololi wela a me nā reactors nukelea.

ʻAe, ʻo alloy718 a me INCONEL 718 e pili ana i ke ʻano like o ka superalloy i hoʻokumu ʻia i ka nickel. ʻO INCONEL 718 kahi hōʻailona kālepa i hoʻopaʻa inoa ʻia o ka Special Metals Corporation, ʻo ia kahi inoa inoa kūikawā no kēia alloy. No laila, kapa pinepine ʻia ka alloy 718 ʻo INCONEL 718.
ʻO INCONEL 718 ʻo UNS N07718. He superalloy ia i hoʻokumu ʻia i ka nickel e hōʻike ana i ka ikaika kiʻekiʻe, ke kūpaʻa i ka pala, a me ka hiki ke hana maikaʻi ʻia, e kūpono ai no nā ʻano hana like ʻole i ka aerospace, ka hana kemika, a me nā wahi wela kiʻekiʻe ʻē aʻe.
ʻAʻohe mea like pololei me INCONEL 718 no ka mea he mea hoʻohuihui nickel kū hoʻokahi ia. Eia nō naʻe, aia kekahi mau mea hoʻohuihui nickel ʻē aʻe i loaʻa nā ʻano like a hiki ke hoʻohana ʻia ma ke ʻano he mau koho ʻē aʻe i kekahi mau noi. ʻO kekahi o kēia mau mea hoʻohuihui:
- ʻO Rene 41
- Waspaloy
- ʻO Hastelloy X
- ʻO Nimonic 80A
- ʻO Haynes 230
Loaʻa i kēia mau mea hoʻohuihui ka ikaika kiʻekiʻe a me nā waiwai kūpaʻa i ka palaho me INCONEL 718 a hoʻohana pinepine ʻia i nā noi like. Eia nō naʻe, he mea nui e noʻonoʻo i nā koi kikoʻī a kūkākūkā me nā ʻenekinia mea a i ʻole nā mea hana metallurgists e hoʻoholo i ke koho kūpono loa no kahi noi kikoʻī.
ʻOiai ʻo INCONEL 718 ka mea i ʻike nui ʻia no kona mau waiwai kūikawā a me ka laulā o nā noi, he mau hemahema kona, e like me:
KumukūʻaiHe ʻano pipiʻi ke kumukūʻai o INCONEL 718 i hoʻohālikelike ʻia me nā mea hoʻohuihui ʻē aʻe, ma muli o kona nui o ka nickel a me ke kaʻina hana paʻakikī. Hiki i kēia ke hoʻolilo iā ia i mea emi ke kumukūʻai no kekahi mau noi me nā kālā haʻahaʻa.
Ka Maʻalahi o ka Hana ʻana i ka Mīkini: He mea paʻakikī ka INCONEL 718 e mīkini. Loaʻa iā ia ke ʻano o ka paʻakikī o ka hana, ʻo ia hoʻi, hiki i nā mea hana ʻoki ke komo koke i ka palaho, e alakaʻi ana i ka hoʻonui ʻia o nā kumukūʻai mea hana a me ka emi ʻana o ka huahana.
Hiki ke hoʻopili ʻia: He palena ko ka hiki ke hoʻopili ʻia ʻo INCONEL 718 a koi ʻia nā ʻenehana a me nā kaʻina hana kūikawā no nā hoʻopili kūleʻa. Hiki i ka hoʻopili ʻana ke hopena i ka hoʻokumu ʻia ʻana o nā māwae a me nā kīnā inā ʻaʻole i hana pololei ʻia, hiki ke hoʻonāwaliwali i ka ʻōnaehana holoʻokoʻa.
Hoʻonui wela: Loaʻa iā INCONEL 718 kahi coefficient kiʻekiʻe o ka hoʻonui wela, ʻo ia hoʻi hiki ke hoʻonui a hoʻemi nui me nā loli o ka mahana. Hiki i kēia ke alakaʻi i ka paʻa ʻole o ka dimensional i kekahi mau noi, e koi ana i nā noʻonoʻo hoʻolālā akahele.
ʻOiai kēia mau hemahema, hoʻohana nui ʻia ʻo INCONEL 718 i nā noi wela kiʻekiʻe like ʻole, e like me ka aerospace, ikehu, a me nā ʻoihana aila a me ke kinoea, kahi i ʻoi aku ai kona hui kūikawā o nā waiwai ma mua o kēia mau palena.
