ʻO nā superalloys nickel-based wrought superalloys he papa o nā mea hana kiʻekiʻe i hoʻolālā ʻia no ka ikaika mechanical kūikawā, ke kū ʻana o nā kolo, a me ka paʻa o ke kūkulu ʻana i nā mahana kiʻekiʻe, maʻamau ma luna o 540°C (1000°F). ʻO ka huaʻōlelo "wrought" e hōʻike ana ua hoʻohālikelike ʻia kēia mau ʻāpana i ko lākou ʻano hope ma o nā kaʻina thermomechanical e like me ka forging, rolling, a extrusion paha, kahi e hopena ai i kahi hoʻolālā palaoa maikaʻi e hāʻawi ai i nā waiwai tensile a me ka luhi i hoʻohālikelike ʻia me kā lākou mau mea hoʻolei. ʻO lākou ka iwi kuamoʻo o nā ʻāpana hoʻololi kiʻekiʻe i ka aerospace a me ka hana mana, kahi i koho ʻole ai ka hemahema.

ʻO nā mea hoʻoheheʻe kūpaʻa i hoʻokumu ʻia i ka Nickel kahi papa o nā mea metala kiʻekiʻe i ʻenekinia mua ʻia e kū i nā kaiapuni ʻino loa. ʻO kā lākou kumu he nickel (Ni) matrix, ka mea kū i ka nui o nā corrosives, i hoʻohui ʻia me nā mea nui ʻē aʻe-ma mua o ka chromium (Cr), molybdenum (Mo), a i kekahi manawa keleawe (Cu) a me ka nitrogen (N) - e hana i kahi ʻohana versatile a ikaika hoʻi o nā mea no nā mea kemika a me nā noi ʻoihana. ʻO lākou ka hopena i ka wā ʻaʻole lawa nā kila kila.

ʻO nā mea hoʻoheheʻe wela kiʻekiʻe i hana ʻia i ka hao he papa o nā mea metala me ka hao (Fe) ma ke ʻano kumu nui, i hana ʻia no ka mālama ʻana i ka ikaika mechanical maikaʻi a me ke kūpaʻa ʻana i ka hoʻohaʻahaʻa (e like me ka oxidation) ma nā mahana kiʻekiʻe, maʻamau i ka laulā o 540°C a 760°C (1000°F a 1400°F). Hōʻike ka inoa "wrought" ua hana ʻia lākou e nā kaʻina thermomechanical e like me ka ʻōwili wela, forging, a extrusion paha, e hoʻomaʻemaʻe i kā lākou microstructure e hāʻawi i kahi hui maikaʻi o ka ikaika, ductility, a me ka fabricability. Hoʻohana lākou ma ke ʻano he kumu kūʻai kūpono a maikaʻi loa no ka nui o nā noi wela kiʻekiʻe, e hoʻopaʻa ana i ka ʻokoʻa hana ma waena o nā kila kila a me nā superalloys nickel a i ʻole cobalt-based.

ʻO nā superalloys hoʻokumu ʻia ʻo Cobalt kahi papa o nā mea metala hana kiʻekiʻe i hoʻolālā ʻia no ka mālama ʻana i ka ikaika mechanical ʻē aʻe, ka paʻa o ka ʻili, a me ke kū ʻana o ka corrosion i nā wela kiʻekiʻe loa, pinepine ma mua o nā mea i hoʻomaka ai nā superalloys nickel-based e nāwaliwali. He kumu pōhaku kumu ia no nā ʻāpana koʻikoʻi i nā kaiapuni koʻikoʻi loa, ʻo ia hoʻi i ka aerospace, nā turbine kinoea ʻenehana, a me nā implants olakino. ʻO kā lākou hana ʻoi aku ka maikaʻi mai kahi matrix cobalt-chromium i hoʻoikaika ʻia a me ka nui o nā ʻāpana carbide paʻakikī.
