5J1480 precision alloy 5J1480 superalloy Iron-nickel alloy E like me nā mea matrix, hiki ke hoʻokaʻawale ʻia i ka superalloy ma muli o ka hao, superalloy ma muli o ka nickel a me ka superalloy cobalt-based. E like me ke kaʻina hana hoʻomākaukau, hiki ke hoʻokaʻawale ʻia i deformed superalloy, hoʻolei superalloy a me ka pauka metallurgy superalloy. E like me ke ʻano o ka hoʻoikaika ʻana, aia nā ʻano hoʻoikaika paʻa paʻa, ʻano hoʻoikaika ʻana i ka ua, ʻano hoʻoikaika ʻana o ka oxide a me ke ʻano hoʻoikaika fiber. Hoʻohana nui ʻia nā alloys kiʻekiʻe i ka hana ʻana i nā mea wela kiʻekiʻe e like me nā turbine blades, alakaʻi vanes, turbine discs, kiʻekiʻe-press compressor discs a me nā keʻena puhi ahi no ka mokulele, naval a me nā ʻoihana kinoea turbines, a hoʻohana pū ʻia i ka hana ʻana. ʻO nā kaʻa aerospace, nā ʻenekini rocket, nā mea hoʻoheheʻe nuklea, nā lako petrochemical a me ka hoʻololi ʻana i ka lanahu a me nā mea hoʻololi ikehu ʻē aʻe.

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy iron-nickel alloy superalloy e pili ana i kahi ʻano mea metala e pili ana i ka hao, nickel a me ka cobalt, hiki ke hana no ka manawa lōʻihi ma kahi wela kiʻekiʻe ma luna o 600 ℃ a ma lalo o kekahi pilikia; a he kiʻekiʻe ʻO ka ikaika wela kiʻekiʻe kiʻekiʻe, maikaʻi ka pale ʻana i ka oxidation a me ka pale ʻana i ka corrosion, ka hana luhi maikaʻi, ka paʻakikī haʻihaʻi a me nā waiwai ʻē aʻe. ʻO ka superalloy kahi hoʻolālā austenite hoʻokahi, nona ka paʻa paʻa maikaʻi a me ka hilinaʻi o ka lawelawe ma nā ʻano wela.

Ma muli o nā hiʻohiʻona hana ma luna, a me ke kiʻekiʻe o ka alloying o nā superalloys, i ʻike ʻia ʻo "super alloys", he mea nui i hoʻohana nui ʻia i ka mokulele, aerospace, petroleum, ʻoihana kemika, a me nā moku. Wahi a nā mea matrix, ua hoʻokaʻawale ʻia nā superalloys i ka hao-based, nickel-based, cobalt-based a me nā superalloys ʻē aʻe. ʻO ka mahana lawelawe o nā mea hoʻoheheʻe wela kiʻekiʻe e hiki ke hiki i 750 ~ 780 ° C. No nā ʻāpana pale wela i hoʻohana ʻia i nā wela kiʻekiʻe, hoʻohana ʻia nā mea hoʻoheheʻe ʻia me ka nickel-based a refractory. Loaʻa nā superalloys Nickel i kahi kūlana kūikawā a koʻikoʻi ma ke kahua holoʻokoʻa o nā superalloys. Hoʻohana nui ʻia lākou no ka hana ʻana i nā ʻāpana wela loa o nā ʻenekini mokulele mokulele a me nā turbine kinoea ʻenehana. Inā hoʻohana ʻia ka ikaika paʻa o 150MPA-100H ma ke ʻano maʻamau, ʻo ka mahana kiʻekiʻe loa e hiki ai i nā nickel alloys ke kū ʻoi aku ma mua o 1100 ° C, aʻo nā nickel alloys ma kahi o 950 ° C, a ʻo nā mea hao i hoʻokumu ʻia he <850 ° C, ʻo ia hoʻi. , ʻoi aku ka kiʻekiʻe o nā ʻāpana nickel e 150°C a hiki i 250°C. No laila, kapa ka poʻe i ka nickel alloy ka puʻuwai o ka ʻenekini. I kēia manawa, ma nā ʻenekini holomua, ʻo nā nickel alloys ka hapalua o ka nui o ke kaumaha. ʻAʻole wale nā ​​lau turbine a me nā keʻena puhi ahi, akā ua hoʻomaka nā ʻāpana turbine a hiki i nā pae hope o nā lau compressor e hoʻohana i nā alloys nickel. Ke hoʻohālikelike ʻia me nā ʻāpana hao, ʻo nā mea maikaʻi o nā nickel alloys: ʻoi aku ka kiʻekiʻe o ka hana ʻana, ka hale paʻa, ka liʻiliʻi o ka pōʻino a me ke kūpaʻa kiʻekiʻe i ka oxidation a me ka corrosion. Ke hoʻohālikelike ʻia me nā ʻāpana kobalt, hiki i nā nickel alloys ke hana ma lalo o ke kiʻekiʻe o ka mahana a me ke koʻikoʻi, ʻoi aku ka nui o ka neʻe ʻana o nā lau.

Paʻa, ʻaʻohe hoʻololi allotropic mai ka lumi wela a i ka wela kiʻekiʻe; He mea koʻikoʻi kēia no ke koho ʻana i mea matrix. Ua ʻike ʻia he ʻano pono o ka hale austenitic ma mua o ka hana ferrite.

Loaʻa i ka Nickel ke kūpaʻa kemika kiʻekiʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia ma lalo o 500 degere, ʻaʻole pili ʻia e ka ea mehana, ka wai a me kekahi mau wai paʻakai wai i nā mahana kula. Hoʻoheheʻe mālie ʻia ʻo Nickel i ka sulfuric acid a me ka waika hydrochloric, akā wikiwiki i ka waikawa nitric.

Loaʻa i ka Nickel ka hiki ke hoʻohuihui maikaʻi, a ʻo ka hoʻohui ʻana i nā ʻano mea hoʻoheheʻe he ʻumi a ʻaʻole i ʻike ʻia nā ʻano pōʻino, e hāʻawi ana i nā mea hiki ke hoʻomaikaʻi i nā waiwai like ʻole o ka nickel.

ʻOiai ʻaʻole ikaika nā waiwai mechanical o ka nickel maʻemaʻe, ʻoi aku ka maikaʻi o kona plasticity, ʻoi aku ka haʻahaʻa haʻahaʻa, ʻaʻole loli nui ka plasticity.

Nā hiʻohiʻona a me ka hoʻohana ʻana: ka ʻike wela haʻahaʻa a me ka resistivity kiʻekiʻe. ʻIke wela ma ke ana wela waena a me nā lako hoʻomalu ʻakomi
