Faa'iidooyinka Muhiimka ah ee Inconel 718

Habka Adkaynta Roobabka– Inconel 718 waxay xooggeeda ka heshaa roobabka marxaladaha γ″ (Ni₃Nb) iyo γ′ (Ni₃(Al,Ti)) inta lagu jiro daaweynta kulaylka gabowga. Marxaladda γ″ waa habka xoojinta koowaad, iyadoo jajabka mugga uu gaarayo qiyaastii 12-20%. Si ka duwan biraha kale ee badan ee adkaynaya roobka, Inconel 718 wuxuu leeyahay jawaab gabow gaabis ah, isagoo bixinaya daaqad ballaaran oo farsamayn iyo alxan aad u fiican.

Xoog Heerkul Sare oo Heer Sare ah oo Heerkul Sare leh– Inconel 718 waxay ilaalisaa xoog xoog badan, daal, iyo gariir-jeexitaan ilaa 700°C (1300°F). Heerkulka 650°C, xooggeeda wax-soo-saarku wuxuu ka sarreeyaa dhammaan walxaha kale ee superalloys-ka ah. Dahaarkani wuxuu muujiyaa iska caabin aad u fiican oo ku jirta heerka 650-700°C, taasoo ka dhigaysa agabka ugu habboon ee adeegga heerkulka sare ee muddada dheer.

Alxan aad u fiican– Inconel 718 waxaa si weyn loogu arkaa inay tahay superalloy-ka ugu badan ee nikkel-ka ku salaysan ee la alxami karo. Si ka duwan birlabyo badan oo adag oo roobka u nugul oo u nugul dildilaaca da'da cadaadiska, Inconel 718 waxaa lagu alxami karaa xaaladaha da'da iyo kuwa duugga ah iyada oo aan lahayn khatar weyn. Birlabku wuxuu muujiyaa iska caabin aad u fiican oo ku wajahan dildilaaca uu keeno alxamida waxaana lagu alxami karaa iyadoo la adeegsanayo hababka alxamida TIG, MIG, shucaaca elektarooniga ah, iyo hababka alxamida laser-ka. Kala-goysyada alxamida badanaa waxay gaaraan xoog bir ah oo u dhow waalidka iyadoo la adeegsanayo daaweyn fudud oo gabowga ka dib alxamida ah.

Awood Heerkul Ballaaran– Daawadu waxay ilaalisaa sifooyinka xasilloon laga bilaabo heerkulka cryogenic (-253°C) ilaa 700°C. Heerkulka cryogenic, xoogga iyo adkaysigu way kordhaan iyada oo aan lahayn kala-guurka ductile-to-frattle, taasoo ka dhigaysa mid ku habboon nidaamyada hydrogen dareeraha ah iyo oksijiinta dareeraha ah. Kala-soociddan hawlgalka ballaaran waa mid naadir ah oo ka mid ah superalloys.

Iska caabinta Daxalka ee Wanaagsan– Iyada oo leh 17-21% chromium, Inconel 718 waxay bixisaa iska caabin aad u fiican oo ku saabsan oksaydheynta, godadka, iyo dildilaaca daxalka ee deegaanno kala duwan. Dahaarkani si fiican ayuu ugu shaqeeyaa biyaha badda, buufinta milixda, warbaahinta aashitada leh, iyo jawiga oksaydhka heerkulka sare leh. Tirada kobalt ee hooseysa (≤1.0%) waxay ka dhigaysaa mid ku habboon codsiyada nukliyeerka halkaas oo kicinta shucaaca ay tahay walaac.

Wax-soo-saarka Wanaagsan– Inconel 718 waxaa lagu shaqayn karaa kuleyl 900-1150°C halka qabowna lagu shaqayn karo iyadoo la adeegsanayo farsamooyinka caadiga ah. Shaqada qabow waxay si weyn u kordhisaa xoogga iyadoo la ilaalinayo isku-xidhnaan ku filan. Dahaarka waxaa lagu farsamayn karaa iyadoo la isticmaalayo qalab carbide ama dhoobo ah oo leh cabbirro ku habboon.

Tixgelinnada Muhiimka ah:

  • Marxaladda γ″ (Ni₃Nb) waa marxaladda xoojinta koowaad waana mid la isku halleyn karo. Marka heerkulku ka sarreeyo 650°C, waxay isu beddeshaa marxaladda δ ee deggan (Ni₃Nb, orthorhombic) taasoo keenta hoos u dhac xoog
  • Soo-gaadhista muddada dheer ee 600-800°C waxay soo saari kartaa marxaladda δ ee xuduudaha hadhuudhka, taasoo yaraynaysa adkaanta
  • Heerka qaboojinta ka dib marka la buufiyo xalka waa inuu ahaadaa mid degdeg ah si loo xakameeyo roobabka waxyeelada leh
