ʻO INCONEL 718 kahi mea hoʻohui nickel ikaika kiʻekiʻe.ʻO ka nickel ka nui, me ka nui o ka chromium, hao, a me nā mea liʻiliʻi o nā mea ʻē aʻe e like me ka molybdenum, niobium, a me ka aluminika.ʻIke ʻia ka alloy no kāna mau ʻano mechanical maikaʻi loa, me ka tensile kiʻekiʻe, ka hoʻoulu ʻana, a me ka ikaika luhi, a me ka paʻakikī maikaʻi a me ke kūʻē ʻana i ka haki ʻana a me ka deformation creep.Hōʻike pū ʻo INCONEL 718 i ke kūpaʻa kūʻokoʻa i ka corrosion, ʻoiai i nā mahana kiʻekiʻe, e kūpono ana ia no ka hoʻohana ʻana i nā wahi ʻino e like me ka aerospace, ka hana kemika, a me nā noi kai.Hoʻohana maʻamau ia i ka hana ʻana i nā ʻāpana turbine gas, nā ʻenekini rocket, a me nā ʻāpana like ʻole i kau ʻia i ke koʻikoʻi kiʻekiʻe a me nā kūlana koʻikoʻi.
ʻO INCONEL 718 kahi superalloy i hoʻokumu ʻia i ka nickel i ʻike ʻia no kāna mau waiwai mechanical kūikawā ma nā wela kiʻekiʻe.ʻO ka nickel ka mea nui, me nā mea liʻiliʻi o nā mea ʻē aʻe e like me chromium, hao, niobium, molybdenum, a me alumini.Hāʻawi ʻo INCONEL 718 i ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion maikaʻi, a me ke kūpaʻa ʻana o ka oxidation maikaʻi loa, kūpono ia no ka hoʻohana ʻana i nā wahi koʻikoʻi e like me ka aerospace a me nā mīkini turbine gas.Hoʻohana maʻamau ia i nā noi e koi ana i ke kūpaʻa wela kiʻekiʻe, e like me nā mea hoʻololi wela a me nā reactors nuklea.

ʻAe, pili ka alloy718 a me INCONEL 718 i ke ʻano like o ka superalloy e pili ana i ka nickel.ʻO INCONEL 718 kahi hōʻailona inoa inoa o ka Special Metals Corporation, kahi inoa inoa kūikawā no kēia hui.No laila, kapa pinepine ʻia ka alloy 718 ma INCONEL 718.
ʻO INCONEL 718 ka UNS N07718.He nickel-based superalloy e hōʻike ana i ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion, a me ka fabricability maikaʻi, e kūpono ana ia no ka nui o nā noi i ka aerospace, ka hana kemika, a me nā wahi wela kiʻekiʻe.
ʻAʻohe mea e like ai me INCONEL 718 no ka mea, he mea hoʻoheheʻe nickel kū hoʻokahi.Eia nō naʻe, aia kekahi mau ʻāpana nickel-based i loaʻa nā ʻano like a hiki ke hoʻohana ʻia ma ke ʻano he mau mea ʻē aʻe i kekahi mau noi.ʻO kekahi o kēia mau alloys penei:
- Rene 41
- Waspaloy
- ʻO Hastelloy X
- Nimonic 80A
- Haynes 230
Loaʻa i kēia mau alloys ka ikaika kiʻekiʻe a me ka corrosion-resistant i ka INCONEL 718 a hoʻohana pinepine ʻia i nā noi like.Eia nō naʻe, pono e noʻonoʻo i nā koi kikoʻī a kūkākūkā me nā mea ʻenehana a i ʻole metallurgists e hoʻoholo i ke koho kūpono loa no kahi noi.
ʻOiai ʻike nui ʻia ʻo INCONEL 718 no kāna mau waiwai kūʻokoʻa a me ka laulā o nā noi, aia kekahi mau hemahema, e like me:
Koina: He kumukūʻai nui ʻo INCONEL 718 i ka hoʻohālikelike ʻia me nā mea hoʻohui ʻē aʻe, ma muli o ka nui o ka nickel content a me ke kaʻina hana paʻakikī.Hiki i kēia ke hoʻemi i ka hoʻokele waiwai no kekahi mau noi me nā kālā haʻahaʻa.
Hiki i ka mīkini: INCONEL 718 mea paʻakikī i ka mīkini.Loaʻa iā ia ka hana paʻakikī, ʻo ia hoʻi e hiki ke hoʻopau koke i nā mea hana, e alakaʻi ana i ka hoʻonui ʻana i nā kumukūʻai mea hana a me ka emi ʻana o ka huahana.
Weldability: INCONEL 718 i kaupalena weldability a koi i nā loea kūikawā a me nā kaʻina hana no nā welds kūleʻa.Hiki i ka welding ke hana i nā māwae a me nā hemahema inā ʻaʻole i hana pono ʻia, hiki ke hoʻonāwaliwali i ka hale holoʻokoʻa.
Hoʻonui wela: He koena kiʻekiʻe ko INCONEL 718 o ka hoʻonui wela, ʻo ia hoʻi hiki iā ia ke hoʻonui a ʻaelike nui me nā loli wela.Hiki i kēia ke alakaʻi i ka instability dimensional i kekahi mau noi, pono e noʻonoʻo pono i ka hoʻolālā.
ʻOiai kēia mau hemahema, hoʻohana nui ʻia ʻo INCONEL 718 i nā noi wela kiʻekiʻe, e like me ka aerospace, ka ikehu, a me nā ʻoihana ʻaila a me ke kinoea, kahi i ʻoi aku ai kona hui ʻana o nā waiwai i kēia mau palena.
