I-5J1480 i-alloy echanekileyo 5J1480 i-superalloy ye-iron-nickel Ngokwezinto ze-matrix, ingahlulwa ibe yi-superalloy esekwe kwi-iron, i-superalloy esekwe kwi-nickel kunye ne-superalloy esekwe kwi-cobalt. Ngokwenkqubo yokulungiselela, ingahlulwa ibe yi-superalloy eguqulweyo, i-superalloy ephoswe nge-casting kunye ne-powder metallurgy superalloy. Ngokwendlela yokuqinisa, kukho uhlobo lokuqinisa isisombululo esiqinileyo, uhlobo lokuqinisa imvula, uhlobo lokuqinisa ukusasazeka kwe-oxide kunye nohlobo lokuqinisa ifayibha. Ii-alloy ezikumgangatho ophezulu zisetyenziswa kakhulu ekwenziweni kwezinto ezikumgangatho ophezulu ezifana nee-turbine blades, ii-guide vanes, ii-turbine discs, ii-compressor discs ezixineneyo kunye nee-combustion chambers zeenqwelo moya, ii-naval kunye nee-industrial gas turbines, kwaye zikwasetyenziswa ekwenziweni kwezithuthi zeenqwelo moya, ii-rocket engines, ii-nuclear reactors, izixhobo ze-petrochemical kunye nezixhobo zokuguqula amandla ngamalahle kunye nezinye izixhobo zokuguqula amandla.

ukusetyenziswa kwezinto

I-5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy iron-nickel alloy superalloy ibhekisa kuhlobo lwezinto zesinyithi ezisekelwe kwisinyithi, i-nickel kunye ne-cobalt, ezinokusebenza ixesha elide kubushushu obuphezulu obungaphezulu kwama-600 ℃ kwaye ziphantsi koxinzelelo oluthile; kwaye zinamandla aphezulu aphezulu obushushu obuphezulu, ukumelana okuhle kwe-oxidation kunye nokumelana nokugqwala, ukusebenza kakuhle kokudinwa, ukuqina kokuqhekeka kunye nezinye iimpawu ezibanzi. I-superalloy sisakhiwo esinye se-austenite, esinozinzo oluhle lwesakhiwo kunye nokuthembeka kwenkonzo kubushushu obahlukeneyo.

Ngokusekelwe kwiimpawu zokusebenza ezingentla, kunye nenqanaba eliphezulu lokuxutywa kwee-superalloys, ezaziwa ngokuba yi-"super alloys", sisixhobo esibalulekileyo esisetyenziswa kakhulu kwiinqwelomoya, kwi-aerospace, kwi-petroleum, kushishino lweekhemikhali, nakwiinqanawa. Ngokwezinto ze-matrix, ii-superalloys zahlulwe zibe zii-superalloys ezisekwe kwisinyithi, kwi-nickel, kwi-cobalt nakwezinye ii-superalloys. Ubushushu benkonzo yee-alloys ezisekwe kwisinyithi ezisekwe kwiqondo eliphezulu lobushushu ngokubanzi bunokufikelela kuphela kwi-750 ~ 780°C. Kwiindawo ezimelana nobushushu ezisetyenziswa kumaqondo obushushu aphezulu, kusetyenziswa ii-alloys ezisekwe kwi-nickel kunye ne-refractory metal-based. Ii-superalloys ezisekwe kwi-nickel zithatha indawo ekhethekileyo nebalulekileyo kulo lonke icandelo lee-superalloys. Zisetyenziswa kakhulu ukuvelisa iindawo ezishushu kakhulu zeenjini zejethi zeenqwelo moya kunye neeturbines ezahlukeneyo zegesi zoshishino. Ukuba amandla aqinileyo e-150MPA-100H asetyenziswa njengomgangatho, ubushushu obuphezulu obunokumelana nee-alloys ze-nickel buyi->1100°C, ngelixa ii-alloys ze-nickel zimalunga ne-950°C, kwaye ii-alloys ezisekelwe kwi-iron zingaphantsi kwe-850°C, oko kukuthi, ii-alloys ezisekelwe kwi-nickel ziphezulu ngokuhambelanayo nge-150°C ukuya malunga ne-250°C. Ngoko ke abantu babiza i-alloy ye-nickel njengentliziyo yenjini. Okwangoku, kwiinjini eziphambili, ii-alloys ze-nickel zithatha isiqingatha sobunzima obupheleleyo. Ayizizo kuphela ii-turbine blades kunye namagumbi okutsha, kodwa neediski ze-turbine kunye nezigaba zokugqibela zee-compressor blades ziqalile ukusebenzisa ii-alloys ze-nickel. Xa kuthelekiswa nee-alloys zesinyithi, iingenelo zee-alloys ze-nickel zezi: ubushushu obuphezulu bokusebenza, isakhiwo esizinzileyo, izigaba ezingonakalisiyo kunye nokumelana okuphezulu kwi-oxidation kunye nokugqwala. Xa kuthelekiswa nee-alloys ze-cobalt, ii-alloys ze-nickel zinokusebenza phantsi kobushushu obuphezulu kunye noxinzelelo, ngakumbi kwimeko yee-blades ezihambayo.

I-5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy I-iron-nickel alloy Iingenelo ezikhankanyiweyo apha ngasentla ze-nickel alloy zinxulumene nezinye zeempawu zayo ezintle. I-Nickel sisakhiwo setyhubhu esijonge ubuso esinobukhulu obuphezulu

Izinzile, akukho tshintsho lwe-allotropic ukusuka kubushushu begumbi ukuya kubushushu obuphezulu; oku kubaluleke kakhulu ekukhetheni njengezinto ze-matrix. Kuyaziwa ukuba ulwakhiwo lwe-austenitic luneenzuzo ezininzi ngaphezu kwesakhiwo se-ferrite.

I-Nickel inamandla aphezulu okumelana neekhemikhali, ayitshisi kangako ngaphantsi kwama-degrees angama-500, kwaye ayichaphazeleki ngumoya ofudumeleyo, amanzi kunye nezinye izisombululo zetyuwa emanzini kubushushu besikolo. I-Nickel inyibilika kancinci kwi-sulfuric acid kunye ne-hydrochloric acid, kodwa ngokukhawuleza kwi-nitric acid.

I-Nickel inamandla amakhulu okudibanisa, kwaye nokuba ukongeza iintlobo ezingaphezu kweshumi zezinto zokudibanisa akubonakali ngathi kuyingozi, nto leyo enika amathuba okuphucula iipropati ezahlukeneyo ze-nickel.

Nangona iipropati zoomatshini ze-nickel ecocekileyo zingomelelanga, i-plasticity yayo ibalasele kakhulu, ingakumbi kubushushu obuphantsi, i-plasticity ayitshintshi kangako.

Iimpawu kunye nokusetyenziswa: ubushushu obuphakathi kunye nokumelana okuphezulu. Inzwa yobushushu ekulinganiseni ubushushu obuphakathi kunye nezixhobo zokulawula ngokuzenzekelayo
