I-5J1480 precision alloy 5J1480 superalloy Iron-nickel alloy Ngokusho kwezakhi ze-matrix, ingahlukaniswa nge-iron-based superalloy, i-nickel-based superalloy kanye ne-cobalt-based superalloy.Ngokwenqubo yokulungiselela, ingahlukaniswa ibe yi-superalloy ekhubazekile, i-casting superalloy kanye ne-powder metallurgy superalloy.Ngokwendlela yokuqinisa, kukhona uhlobo oluqinile lokuqinisa isixazululo, uhlobo lokuqinisa imvula, uhlobo lokuqinisa ukuhlakazeka kwe-oxide kanye nohlobo lokuqinisa i-fiber.Ama-alloys asezingeni eliphezulu asetshenziswa kakhulu ekwenzeni izingxenye ezishisa kakhulu zokushisa njengama-turbine blades, ama-vanes omhlahlandlela, ama-disc ophephela, ama-high-pressure compressor discs namakamelo avuthayo ezindiza, izinjini zegesi zasolwandle nezezimboni, futhi asetshenziswa nasekukhiqizeni. wezimoto zasemkhathini, izinjini zamarokhethi, ama-reactors enuzi, okokusebenza kwe-petrochemical kanye nokuguqulwa kwamalahle kanye nezinye izinto zokuguqula amandla.

ukusetshenziswa kwezinto ezibonakalayo

I-5J1480 i-bimetal eshisayo engu-5J1480 enembile i-alloy 5J1480 superalloy iron-nickel alloy superalloy ibhekisela ohlotsheni lwensimbi esekelwe kunsimbi, i-nickel ne-cobalt, engasebenza isikhathi eside ekushiseni okuphezulu ngaphezu kuka-600 ℃ nangaphansi kokucindezeleka okuthile;futhi inamandla aphezulu aphezulu okushisa aphezulu, ukumelana okuhle kwe-oxidation nokumelana nokugqwala, ukusebenza kahle kokukhathala, ukuqina kokuphuka kanye nezinye izici ezibanzi.I-superalloy iyisakhiwo esisodwa se-austenite, esinokuqina okuhle kwesakhiwo nokuthembeka kwesevisi emazingeni okushisa ahlukahlukene.

Ngokusekelwe ezicini zokusebenza ezingenhla, kanye nezinga eliphezulu le-alloying ye-superalloys, eyaziwa nangokuthi "ama-super alloys", iyinto ebalulekile esetshenziswa kabanzi kwezokundiza, i-aerospace, i-petroleum, imboni yamakhemikhali, nemikhumbi.Ngokusho kwezakhi ze-matrix, ama-superalloys ahlukaniswe abe yi-iron-based, i-nickel-based, i-cobalt-based kanye namanye ama-superalloys.Izinga lokushisa lesevisi lama-alloys asekelwe ku-iron-high-temperature ngokuvamile lingafinyelela kuphela ku-750 ~ 780°C.Ezingxenyeni ezimelana nokushisa ezisetshenziswa emazingeni okushisa aphezulu, ama-alloys asekelwe ku-nickel kanye ne-refractory metal-based asetshenziswa.Ama-superalloys asekelwe ku-nickel athatha isikhundla esikhethekile nesibalulekile kuwo wonke umkhakha wama-superalloys.Asetshenziswa kabanzi ukwenza izingxenye ezishisa kakhulu zezinjini zezindiza zezindiza kanye nezinjini zegesi ezihlukene zezimboni.Uma amandla ahlala isikhathi eside we-150MPA-100H esetshenziswa njengezinga elijwayelekile, izinga lokushisa eliphakeme kakhulu ama-nickel alloys angamelana nalo lingu->1100°C, kuyilapho ama-nickel alloys ecishe abe ngu-950°C, nama-alloys asekelwe ku-iron angu-<850°C, okusho ukuthi. , ama-alloys asekelwe ku-nickel aphakeme ngokuhambisanayo ngo-150°C kuya cishe ku-250°C.Ngakho abantu babiza ingxube ye-nickel inhliziyo yenjini.Njengamanje, ezinjinini ezithuthukisiwe, ama-nickel alloys ayingxenye yesisindo esiphelele.Akuwona nje ama-turbine blades kanye namagumbi omlilo, kodwa namadiski omoya kanye nezigaba zokugcina ze-compressor blades seziqalile ukusebenzisa ama-nickel alloys.Uma kuqhathaniswa nama-alloys ensimbi, izinzuzo ze-nickel alloys yilezi: izinga lokushisa eliphezulu lokusebenza, isakhiwo esizinzile, izigaba ezinobungozi obuncane kanye nokumelana okuphezulu kwe-oxidation nokugqwala.Uma kuqhathaniswa nama-alloys e-cobalt, ama-nickel alloys angasebenza ngaphansi kokushisa okuphezulu nokucindezeleka, ikakhulukazi uma kwenzeka ama-blade ahambayo.

Izinzile, akukho ukuguqulwa kwe-allotropic kusuka ekamelweni lokushisa kuya ekushiseni okuphezulu;lokhu kubaluleke kakhulu ekukhethweni njengento ye-matrix.Kuyaziwa ukuthi ukwakheka kwe-austenitic kunochungechunge lwezinzuzo ngaphezu kwesakhiwo se-ferrite.

I-Nickel inokuqina kwamakhemikhali aphezulu, ayifaki oksijini ngaphansi kwamadigri angu-500, futhi ayithinteki emoyeni ofudumele, amanzi kanye nezixazululo ezithile zikasawoti omanzi emazingeni okushisa esikoleni.I-nickel incibilika kancane ku-sulfuric acid ne-hydrochloric acid, kodwa ngokushesha ku-nitric acid.

I-Nickel inekhono elikhulu lokuhlanganisa, futhi ngisho nokwengeza izinhlobo ezingaphezu kweshumi zezakhi ze-alloying akubonakali izigaba eziyingozi, okunikeza amathuba angaba khona okuthuthukisa izakhiwo ezihlukahlukene ze-nickel.

Nakuba izakhiwo zemishini ye-nickel ehlanzekile azinamandla, ipulasitiki yayo ihle kakhulu, ikakhulukazi ekushiseni okuphansi, i-plasticity ayishintshi kakhulu.

Izici nokusetshenziswa: ukuzwela ukushisa okumaphakathi kanye nokumelana okuphezulu.Inzwa eshisayo esilinganisweni sezinga lokushisa elimaphakathi nemishini yokulawula okuzenzakalelayo
