Zithunzi za Inconel X-750
Inconel X-750 alloy makamaka ndi faifi tambala superalloy yomwe imalimbitsa zaka ndi γ[Ni3(Al, Ti, Nb)] gawo.Ili ndi kukana bwino kwa dzimbiri komanso kukana kwa okosijeni pansi pa 980 ℃, ndipo pansi pa 800 ℃ ili ndi kukana kwambiri kwa dzimbiri.Ili ndi kukana kwabwino kopumula pansi pa 540 ° C, komanso mawonekedwe abwino komanso kuwotcherera.Aloyiyi imagwiritsidwa ntchito makamaka popanga injini za ndege zomwe zimagwira ntchito pansi pa 800 ° C ndipo zimafuna mphamvu zambiri..Akasupe amathanso kugwiritsidwa ntchito popanga masamba a turbine turbine ndi magawo ena, monga mbale, mipiringidzo, mipiringidzo, ma forgings, mphete, mawaya, mapaipi, ndi zina.
Inconel X-750 Njira Yochizira Kutentha
Njira yothetsera kutentha kwa mbale, mipiringidzo ndi mapaipi omwe ali pamalo operekera ndi 980 ℃ ± 15 ℃, kuzirala kwa mpweya.Kwa njira yapakati yopangira kutentha kwa zipangizo ndi zigawo, njira zotsatirazi zingasankhidwe pofuna chithandizo cha kutentha.
Annealing: 955 ~ 1010 ℃, kuzirala kwa madzi.
Annealing wa welded mbali pamaso kuwotcherera: 980 ℃, 1h.
Kuchepetsa kupsinjika kwa magawo owotcherera: 900 ℃, moisturizing kwa 2h.
Kuchepetsa kupsinjika: 885 ℃ ± 15 ℃, 24h, kuziziritsa kwa mpweya.
Inconel X-750 Mitundu Yopezeka ndi Mafotokozedwe
Ma bar, forgings, mphete, mapepala otentha, mapepala ozizira ozizira, mikwingwirima, machubu ndi mawaya akhoza kuperekedwa mosiyanasiyana.
Mbale ndi zingwe nthawi zambiri zimaperekedwa pambuyo pakutentha kapena kuzizira, kukulunga kapena njira, pickling ndi kupukuta.
Mipiringidzo, forgings ndi mphete zitha kuperekedwa m'malo opukutidwa kapena otentha;Angathenso kuperekedwa mu njira yothetsera mankhwala pambuyo forging;mipiringidzo imatha kuperekedwa pambuyo pa yankho ndikupukutidwa kapena kutembenuzidwa, ndipo ikhoza kuperekedwa mozizira pamene dongosolo likufuna kuti Pull state ikhazikike.
Waya akhoza kuperekedwa mu chikhalidwe cholimba;kwa waya wokhala ndi m'mimba mwake mwadzina kapena makulidwe ochepera 6.35mm, imatha kukhala yankho lolimba ndikuperekedwa ndi mawonekedwe ozizira a 50% mpaka 65%;m'mimba mwake mwadzina kapena mbali kutalika ndi wamkulu kuposa 6.35mm.Waya, pambuyo pa chithandizo chamankhwala, amaperekedwa ndi mapindikidwe ozizira ozizira osachepera 30%.Kwa mawaya okhala ndi m'mimba mwake mwadzina kapena utali wam'mbali osaposa 0.65mm, amatha kuperekedwa ndi mawonekedwe ozizira opaka osakwana 15% mutatha chithandizo chamankhwala ngati pakufunika.
Magawo Ogwiritsa Ntchito Inconel X-750
Aloyi imagwiritsidwa ntchito makamaka popanga akasupe amasamba ndi akasupe a coil okhala ndi mphamvu zambiri komanso kukana kupumula kwa injini za aero zomwe zimagwira ntchito pansi pa 800 ° C.Itha kugwiritsidwanso ntchito kupanga magawo ngati masamba a turbine.Mitundu yomwe ilipo ndi ma sheet, strip, bar, forging, mphete, waya ndi chubu.
