Ukubuka Konke Komkhiqizo
I-Inconel 718 (UNS N07718 /I-W.Nr. 2.4668 / GH4169) iyi-alloy ye-nickel-chromium-iron eqina imvula enamandla aphezulu okushisa kanye nokumelana nokugqwala. I-Womic Steel inikeza i-Inconel 718 ngezindlela eziningi zemikhiqizo kufaka phakathi ipayipi elingenamthungo, ipayipi elihlanganisiwe, ibha yensimbi, ipuleti lensimbi, ikhoyili yensimbi, umcu, ama-flange, izinto zokufaka, izinto zokubopha, ucingo, izinamathiselo, nama-valve ezindiza, i-turbine yegesi, i-marine, i-nuclear, kanye nezicelo zikawoyela negesi.
I-Inconel 718 iyi-superalloy esetshenziswa kakhulu emhlabeni wonke esekelwe ku-nickel, evame ukuchazwa ngokuthi "ihhashi elisebenzayo" lama-alloy anokushisa okuphezulu. Yasungulwa yi-International Nickel Company ngawo-1950, i-alloy ithola amandla ayo ahlukile ngokuna kwe-γ″ (Ni₃Nb) kanye ne-γ′ (Ni₃(Al,Ti)) ngesikhathi sokwelashwa kokushisa okulawulwayo okuguga kabili. Njengoba amandla okuthambekela efika ku-1,275-1,380 MPa, i-Inconel 718 inikeza enye yezilinganiso zamandla nesisindo eziphakeme kakhulu phakathi kwama-alloy e-nickel ngenkathi igcina ukuthungwa okuhle kakhulu kanye nokushintshwa.

Izinzuzo Eziyinhloko ze-Inconel 718
Indlela Yokuqinisa Imvula– I-Inconel 718 ithola amandla ayo ekunabeni kwezigaba ze-γ″ (Ni₃Nb) kanye ne-γ′ (Ni₃(Al,Ti)) ngesikhathi sokwelashwa kokushisa kokuguga. Isigaba se-γ″ siyindlela eyinhloko yokuqinisa, kanti ingxenye yevolumu ifinyelela cishe ku-12-20%. Ngokungafani nezinye izinhlobo eziningi zokuqinisa imvula, i-Inconel 718 inempendulo yokuguga ehamba kancane, inikeza ifasitela elibanzi lokucubungula kanye nokushibilika okuhle kakhulu.
Amandla Aphakeme Okushisa Okumangalisayo– I-Inconel 718 igcina amandla aphezulu okudonseka, ukukhathala, kanye nokuqhekeka kokuqhekeka kuze kufike ku-700°C (1300°F). Ku-650°C, amandla ayo okukhiqiza adlula lawo wonke amanye ama-superalloy asetshenzisiwe. I-alloy ibonisa ukumelana okuhle kakhulu kokuqhekeka ebangeni lika-650-700°C, okwenza kube yinto ekhethwayo yesevisi yesikhathi eside yokushisa okuphezulu.
Ukushibilika Okuhle Kakhulu– I-Inconel 718 ibhekwa kabanzi njenge-superalloy esuselwe ku-nickel eshibilikayo kakhulu. Ngokungafani nama-alloy amaningi okuqinisa imvula asengozini yokuqhekeka kokuguga, i-Inconel 718 ingashibilika ezimweni ezifakwe i-anneal kanye nezindala ngaphandle kwengozi enkulu. I-alloy ibonisa ukumelana okuhle kakhulu nokuqhekeka okubangelwa ukushibilika futhi ingashibilika kusetshenziswa izinqubo zokushibilika ze-TIG, MIG, electron beam, kanye ne-laser. Amajoyinti ashibilikayo ngokuvamile athola amandla ensimbi aseduze nomzali ngokwelashwa okulula kokuguga ngemva kokushibilika.
Amandla Okushisa Okubanzi– Ingxube igcina izakhiwo ezizinzile kusukela emazingeni okushisa acwebezelayo (-253°C) kuze kufike ku-700°C. Emazingeni okushisa acwebezelayo, amandla nokuqina kuyanda ngaphandle kokushintshashintsha kwe-ductile kuya ku-brittle, okwenza ifanelekele izinhlelo ze-hydrogen ewuketshezi kanye ne-oxygen ewuketshezi. Lolu hlu olubanzi lokusebenza aluvamile phakathi kwama-superalloy.
Ukumelana Okuhle Kokugqwala– Ngokuqukethwe kwe-chromium okungu-17-21%, i-Inconel 718 inikeza ukumelana okuhle kakhulu nokuqhekeka kokugqwala, umgodi, kanye nokugqwala kokucindezeleka ezindaweni ezahlukahlukene. Ingxube isebenza kahle emanzini olwandle, ekufakweni kukasawoti, e-acidic media, kanye nasezindaweni ezishisa kakhulu zokugqwala. Okuqukethwe kwayo okuphansi kwe-cobalt (≤1.0%) kwenza ifaneleke ukusetshenziswa kwenuzi lapho ukusebenza kwemisebe kuyinkinga.
Ukwenziwa Okuhle Kakhulu– I-Inconel 718 ingashiswa ngokushisa ku-900-1150°C futhi isetshenziswe ngokubanda kusetshenziswa amasu ajwayelekile. Ukusebenza ngokubanda kwandisa kakhulu amandla ngenkathi kugcinwa ukuguquguquka okwanele. Ingxube iyashintshwa kusetshenziswa i-carbide noma i-ceramic tooling enemingcele efanele.
Ukwelashwa Kokushisa kwe-Inconel 718

Izicelo ze-Inconel 718
Izindiza– I-Inconel 718 iyindinganiso yemboni yezingxenye zenjini yejethi okuhlanganisa amadiski e-compressor anomfutho ophezulu, amadiski e-turbine, imiphini ye-turbine, ama-compressor blades, amakamelo okushisa, izingxenye ze-afterburner, kanye nama-casing enjini. I-alloy isetshenziselwa futhi izingxenye ze-rocket motor, amakamelo okuthungela, ama-turbopump, kanye nezakhiwo zezindiza. Yi-superalloy esetshenziswa kakhulu ekusetshenzisweni kwezindiza.
Amandla Nokukhiqiza Amandla– Ingxube isetshenziswa kakhulu ezingxenyeni ze-turbine yegesi kufaka phakathi amadiski e-turbine, ama-blade, ama-transition ducts, kanye nezinamathiselo zama-turbine egesi asemhlabeni kanye nawasolwandle. Ukumelana kwayo nokukhukhuleka ku-650-700°C kuyenza ifaneleke isevisi yesikhathi eside emishinini yokukhiqiza ugesi.
Imboni Yenuzi– I-Inconel 718 isetshenziswa emithanjeni yokucindezela kwe-reactor, kumapayipi e-steam generator, kuma-control rod drive mechanisms, kanye nasezintweni zangaphakathi eziyinhloko. Okuqukethwe kwayo okuphansi kwe-cobalt (≤1.0%) kunciphisa ukusebenza kwe-radioactive, okwenza ifaneleke ukusetshenziswa kwe-nuclear.
Uwoyela negesi– Ingxube ichazwe imishini yokucindezela okuphezulu kokushisa okuphezulu (HPHT), izingxenye zeshubhu ezingaphansi komhlaba, iziphanyeko zamapayipi, amavalvu, amaphampu, kanye nemishini engaphansi kolwandle ezindaweni zesevisi emuncu. I-Inconel 718 imelana nokuqhekeka kokucindezeleka kwe-sulfide kanye nokuqhekeka okubangelwa yi-hydrogen ezindaweni eziqukethe i-H₂S.
Izibambo Zokushisa Okuphezulu– I-Inconel 718 iyinto ejwayelekile yezibambo zokushisa okuphezulu okuhlanganisa amabhawodi e-turbine, ama-stud, amantongomane, nezikulufo ezisebenza emazingeni okushisa afinyelela ku-700°C. Ukumelana kwayo nokukhululeka kokucindezeleka kuqinisekisa ubuqotho besikhathi eside bamalunga.
Izinhlelo Zokusebenza Ze-Cryogenic– Ingxube igcina ukuqina okungavamile emazingeni okushisa aphansi afinyelela ku--253°C, okwenza ifaneleke emathangini nasezinhlelweni zokugcina i-hydrogen ewuketshezi kanye ne-oxygen ewuketshezi.

A: Okulingana kwesiShayina yi-GH4169 kanye ne-GH169 (GB/T 14992). Lawa mabanga ahambisana nezindinganiso zikazwelonke zaseShayina zama-alloys okushisa okuphezulu.
U: Yimaphi amafomu omkhiqizo atholakalayo e-Inconel 718?
A: I-Womic Steel inikeza i-Inconel 718 ngepayipi elingenamthungo, ipayipi elihlanganisiwe, ibha yensimbi, ipuleti lensimbi, ikhoyili yensimbi, umcu, ama-flange, izinto zokufaka, izinto zokubopha, ucingo, iziphethu, izinamathiselo, nama-valve. Imininingwane ephelele yomkhiqizo kanye nobubanzi bosayizi kubhalwe esigabeni sokutholakala komkhiqizo.
Q: Ingabe i-Inconel 718 idinga ukwelashwa ngokushisa?
A: Yebo. I-Inconel 718 ithola amandla ayo angavamile ngokwelashwa kokushisa okuqinisa imvula. Inqubo ejwayelekile iwukubanda ngesisombululo (927-1010°C) kulandelwe ukuguga kabili (718°C amahora angu-8, ukupholisa isithando somlilo kufinyelele ku-620°C, kubambe amahora angu-8-10).
Q: Ingabe i-Inconel 718 inamandla kazibuthe?
A: Cha. I-Inconel 718 ayisebenzisi i-magnetic kuzo zonke izimo, okwenza ifaneleke ukusetshenziswa lapho kufanele kugwenywe khona ukuphazamiseka kwe-magnetic.
Q: Iyini ukusebenza kokukhathala kwe-Inconel 718?
A: I-Inconel 718 ikhombisa ukumelana nokukhathala okumangalisayo emazingeni okushisa aphezulu. Umkhawulo wayo wokukhathala okuphezulu (HCF) ku-650°C udlula i-400 MPa, okwenza ifaneleke ukusetshenziswa ngaphansi komthwalo we-cyclic kanye nokukhathala kokushisa.
