Nickel-based wrought superalloys yog qhov tseem ceeb hauv cov kev xav tau ntau tshaj plaws:
Aerospace Dav Hlau Cav:
Turbine Discs: Daim ntawv thov tseem ceeb tshaj plaws. Discs ua haujlwm ntawm kev sib hloov ceev thiab kev ntxhov siab, yuav tsum muaj qhov sib npaug ntawm lub zog tensile, qaug zog lub neej, thiab tawg toughness. Alloys zoo li Inconel 718 thiab Waspaloy yog cov qauv kev lag luam.
Shafts, Spacers, thiab Compressor Cheebtsam.
Av-Based Gas Turbines: Rau kev tsim hluav taws xob, siv nyob rau hauv turbine discs thiab hniav.
Rocket Engines: Rau turbopump Cheebtsam uas yuav tsum tau muaj zog-rau-hnyav sib piv nyob rau hauv huab ib puag ncig.
Nuclear Reactors & Kub-kub Fasteners.
Cov lus hauv qab no qhia txog cov yam ntxwv tseem ceeb rau kev saib xyuas sai:
| Feature | Kev piav qhia | Qhov zoo |
| Txoj kev tsim khoom | Thermomechanical processing (Forging, Rolling). | Ua ib qho kev ua kom zoo zoo, cov qauv zoo li qub rau qhov zoo tshaj qhov kub thiab txias tensile thiab qaug zog. |
| Qhov tseem ceeb Strengthening Phase | Gamma-Prime (γ') [Ni₃(Al, Ti)] nag xob nag cua. | Muab lub ntsiab mechanism rau high-temperature zog thiab creep kuj. |
| Cov khoom tseem ceeb | Tensile & Fatigue Strength, Creep Resistance, Fracture Toughness. | Qhov zoo tshaj plaws rau kev ntxhov siab, kev sib hloov siab zoo li turbine discs. |
| Hom ntawv | Billets, tuav, rods, nplooj ntawv, thiab rings. | Qhov pib Tshuag rau machining tseem ceeb rotating qhov chaw. |
| Iconic alloys | Inconel 718, Waspaloy, Alloy 720, René 41, Udimet 720. | Sawv cev rau evolution ntawm alloy tsim rau kev xav tau kev ua tau zoo. |
| Primary Industries | Aerospace (Jet Engines), Fais Fab Tsim, Rocketry. | Ua kom lub cav siab dua thiab qhov kub thiab txias, ua rau muaj kev ua haujlwm zoo dua thiab muaj zog. |
Hauv cov ntsiab lus, Nickel-raws li Wrought Superalloys sawv cev rau lub pinnacle ntawm metallic khoom science rau high-stress, high-temperature rotating Cheebtsam. Lawv cov chemistry complex thiab ua tib zoo tswj wrought microstructure ua rau lawv tseem ceeb rau kev thawb cov ciam teb ntawm kev ua tau zoo thiab kev ua haujlwm zoo hauv kev siv dav hlau niaj hnub thiab lub zog.
