Ukubuka Konke Komkhiqizo

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 eziphezulu kakhulu phakathi kwama-alloy e-nickel ngenkathi igcina ukwakheka 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 yi-weld futhi ingashibilika kusetshenziswa izinqubo ze-TIG, MIG, electron beam, kanye ne-laser welding. Amajoyinti ashibilikayo ngokuvamile athola amandla ensimbi acishe abe ngumzali ngokwelashwa okulula kokuguga ngemva kokushibilika.

Amandla Okushisa Okubanzi– Ingxube igcina izakhiwo ezizinzile kusukela emazingeni okushisa e-cryogenic (-253°C) kuze kufike ku-700°C. Emazingeni okushisa e-cryogenic, 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, ukugoba, kanye nokugqwala ezindaweni ezahlukahlukene. Ingxube isebenza kahle emanzini olwandle, ekufakweni kukasawoti, ezindaweni ezine-acidic, 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 ingashintshwa kusetshenziswa i-carbide noma i-ceramic tooling enemingcele efanele.

Isikhathi sokukhetha i-Inconel 718:Izinhlelo zokusebenza ezidinga amandla aphezulu okushisa aphezulu, ukumelana nokukhukhuleka, kanye nokusebenza kokukhathala okufika ku-700°C lapho ukumelana nokugqwala kungokwesibili. Okuvamile: izingxenye ze-turbine, izinjini ze-rocket, uwoyela negesi ye-HPHT.

Isikhathi sokukhetha i-Inconel 625:Izicelo ezidinga ukumelana nokugqwala okuhle kakhulu emanzini olwandle, ama-asidi, kanye nezindawo ezine-chloride ephezulu lapho amandla aphakathi ayamukeleka khona. Okuvamile: amapayipi olwandle, ukucubungula amakhemikhali, izinhlelo ze-FGD.

Ukwelashwa Kokushisa kwe-Inconel 718

I-Inconel 718 idinga ukulandelana okuthile kokwelashwa kokushisa ukuze kufezwe izakhiwo ezinhle kakhulu zemishini:

Ukwelashwa Okujwayelekile Kokushisa:

1. Isixazululo se-Anneal:927-1010°C (1700-1850°F) ihora eli-1, ukupholisa okusheshayo (ukucima amanzi noma uwoyela)

Inhloso: Ncibilikisa zonke izinhlayiya, ufinyelele i-austenite yesigaba esisodwa

2. Ukuguga Kwesigaba Sokuqala:718°C (1325°F) amahora angu-8, pholile ku-620°C

3. Ukuguga Kwesigaba Sesibili:620°C (1150°F) amahora angu-8-10, isikhathi sokuguga siphelele amahora angu-18, umoya upholile

Inhloso: Ukunisela u-γ″ no-γ′ ukuze uthole amandla aphezulu kanye nokumelana nokukhasa

Ukwelashwa Kokushisa Okuhlukile (Ukuthuthukisa Ukuphumula Kokucindezeleka):

Isixazululo se-Anneal:1038-1066°C (1900-1950°F), ukupholisa okusheshayo
Ukuguga Kwesigaba Sokuqala:760°C (1400°F) amahora ayi-10, pholile ku-650°C
Ukuguga Kwesigaba Sesibili:650°C (1200°F) amahora angama-20, umoya upholile

Izinto Ezibalulekile Okufanele Uzicabangele:

Isigaba se-γ″ (Ni₃Nb) yisigaba esiyinhloko sokuqinisa futhi sizinzile. Ngaphezu kuka-650°C, siguquka sibe yisigaba se-δ esizinzile (Ni₃Nb, orthorhombic) okubangela ukwehla kwamandla
Ukuchayeka isikhathi eside ku-600-800°C kunganciphisa isigaba se-δ emingceleni yokusanhlamvu, kunciphise ukuqina
Izinga lokupholisa ngemva kokufakwa kwesisombululo kumele lisheshe ukuze kuncishiswe imvula eyingozi

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 iwukubamba isixazululo (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.
