5J1480 precision alloy 5J1480 superalloy Iron-nickel alloy Wahi a nā mea matrix, hiki ke hoʻokaʻawale ʻia i ka superalloy hao, ka superalloy nickel a me ka superalloy cobalt. Wahi a ke kaʻina hana hoʻomākaukau, hiki ke hoʻokaʻawale ʻia i ka superalloy deformed, ka superalloy hoʻolei a me ka superalloy metallurgy pauka. Wahi a ke ʻano hoʻoikaika, aia ke ʻano hoʻoikaika hopena paʻa, ke ʻano hoʻoikaika precipitation, ke ʻano hoʻoikaika oxide dispersion a me ke ʻano hoʻoikaika fiber. Hoʻohana nui ʻia nā alloys wela kiʻekiʻe i ka hana ʻana i nā ʻāpana wela kiʻekiʻe e like me nā pahi turbine, nā vanes alakaʻi, nā disc turbine, nā disc compressor pressure kiʻekiʻe a me nā keʻena kuni no nā mokulele, nā turbines kinoea moana a me nā ʻoihana, a hoʻohana ʻia hoʻi i ka hana ʻana i nā kaʻa aerospace, nā mīkini rocket, nā reactors nukelea, nā lako petrochemical a me ka hoʻololi lanahu a me nā mea hoʻololi ikehu ʻē aʻe.

ʻO 5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy iron-nickel alloy superalloy e pili ana i kahi ʻano metala i hoʻokumu ʻia i ka hao, nickel a me ka cobalt, hiki ke hana no ka manawa lōʻihi ma kahi mahana kiʻekiʻe ma luna o 600 ℃ a ma lalo o kekahi kaumaha; a he ikaika wela kiʻekiʻe maikaʻi loa, kūpaʻa maikaʻi i ka oxidation a me ke kūpaʻa i ka corrosion, hana luhi maikaʻi, paʻakikī haki a me nā waiwai piha ʻē aʻe. ʻO ka superalloy kahi ʻano austenite hoʻokahi, nona ke kūpaʻa maikaʻi o ka ʻano a me ka hilinaʻi lawelawe ma nā mahana like ʻole.

Ma muli o nā ʻano hana i luna, a me ke kiʻekiʻe o ka hoʻohuihui ʻana o nā superalloys, i ʻike ʻia hoʻi ʻo "super alloys", he mea nui ia i hoʻohana nui ʻia i ka mokulele, aerospace, petroleum, ʻoihana kemika, a me nā moku. Wahi a nā mea matrix, ua māhele ʻia nā superalloys i nā superalloys hao, nickel, cobalt a me nā superalloys ʻē aʻe. ʻO ka mahana lawelawe o nā alloys wela kiʻekiʻe hao ma ke ʻano laulā hiki ke hiki i 750 ~ 780 °C. No nā ʻāpana pale wela i hoʻohana ʻia i nā mahana kiʻekiʻe, hoʻohana ʻia nā alloys metala nickel a me refractory. Noho nā superalloys nickel i kahi kūlana kūikawā a koʻikoʻi ma ke kahua holoʻokoʻa o nā superalloys. Hoʻohana nui ʻia lākou e hana i nā ʻāpana wela loa o nā mīkini mokulele a me nā turbine kinoea ʻoihana like ʻole. Inā hoʻohana ʻia ka ikaika paʻa o 150MPA-100H ma ke ʻano he kūlana, ʻo ke ana wela kiʻekiʻe loa e hiki ai i nā hui nickel ke kū i ka >1100°C, ʻoiai ʻo nā hui nickel ma kahi o 950°C, a ʻo nā hui hao ma lalo o 850°C, ʻo ia hoʻi, ʻoi aku ke kiʻekiʻe o nā hui nickel ma 150°C a i kahi o 250°C. No laila, kapa ka poʻe i ka hui nickel ʻo ia ka puʻuwai o ka ʻenekini. I kēia manawa, i nā ʻenekini holomua, ʻo nā hui nickel ka hapalua o ke kaumaha holoʻokoʻa. ʻAʻole wale nā ​​​​​​lau turbine a me nā keʻena kuni, akā, ʻo nā disks turbine a me nā pae hope o nā lau compressor ua hoʻomaka e hoʻohana i nā hui nickel. Ke hoʻohālikelike ʻia me nā hui hao, ʻo nā pono o nā hui nickel: ʻoi aku ka mahana hana, ka hoʻonohonoho paʻa, nā pae liʻiliʻi ʻino a me ke kūʻē kiʻekiʻe i ka oxidation a me ka corrosion. Ke hoʻohālikelike ʻia me nā hui cobalt, hiki i nā hui nickel ke hana ma lalo o ke ana wela a me ke kaumaha, ʻoi aku hoʻi i ke ʻano o nā lau e neʻe ana.

5J1480 bimetal wela 5J1480 metala kikoʻī 5J1480 superalloy Metala hao-nickel ʻO nā pono i ʻōlelo ʻia ma luna nei o ka metala nickel e pili ana i kekahi o kona mau waiwai maikaʻi loa. He ʻano cubic maka-kikowaena ʻo Nickel me kahi ʻano nui loa

Paʻa, ʻaʻohe hoʻololi allotropic mai ka mahana o ka lumi a i ka mahana kiʻekiʻe; he mea nui loa kēia no ke koho ʻana ma ke ʻano he mea matrix. Ua ʻike maopopo ʻia he nui nā pono o ke ʻano austenitic ma mua o ke ʻano ferrite.

He kiʻekiʻe ke kūpaʻa kemika o ka nikela, ʻaʻole ia e oxidize ma lalo o 500 degere, a ʻaʻole i hoʻopilikia ʻia e ka ea mahana, ka wai a me kekahi mau hopena paʻakai wai i nā mahana kula. Hoʻoheheʻe mālie ʻo Nickel i loko o ka waikawa sulfuric a me ka waikawa hydrochloric, akā wikiwiki i loko o ka waikawa nitric.

He hiki ke hoʻohuihui ʻia ʻo Nickel, a ʻo ka hoʻohui ʻana i nā ʻano mea hoʻohuihui he ʻumi a ʻoi aku paha, ʻaʻole ia he mau pae ʻino, kahi e hāʻawi ai i nā manawa kūpono no ka hoʻomaikaʻi ʻana i nā ʻano like ʻole o ka nickel.

ʻOiai ʻaʻole ikaika nā waiwai mechanical o ka nickel maʻemaʻe, maikaʻi loa kona plasticity, ʻoiai ma ka mahana haʻahaʻa, ʻaʻole nui ka loli o ka plasticity.

Nā hiʻohiʻona a me nā hoʻohana: ʻike wela waena a me ke kū'ē kiʻekiʻe. ʻIke wela i ke ana wela waena a me nā lako hoʻokele aunoa
