Vim li cas niobium ntxiv rau cov hlau?
Niobium (nb) ntxiv rau cov hlau feem ntau yog aMicroalloying CaijTxhawm rau txhim kho nws cov khoom siv tshuab, txheej txheem, thiab durability, txawm tias ntawm cov kev sib haum xeeb (feem ntau-0.15% los ntawm qhov hnyav). Nws cov txiaj ntsig tseem ceeb los ntawm nws lub peev xwm los ua kom zoo, ruaj khov precipitates thiab ua kom cov hlau lub microstructure:
Qoob loo nplej: Thaum Niobium dissolves hauv cov hlau molten, nws kub siab nrog carbon thiab nitrogen los tsim nanoscale carbide (NBC) thiab Niobium Nitride (NBN). Cov lus ua tau zoo li "cov nplej sib txawv ntawm cov ntxig sib luag" thaum kev sib tw ntawm cov hmoov loj, cov nplej qaug zog. Cov nplej nplej nplua (txo los ntawm 100-200 μ6 rau 1-10 μm) hloov kho lub zog thiab tawv los ntawm kev txwv kev tshem tawm.
Txhim kho lub zog tsis muaj qhov hnyav: Los ntawm Refining Nplej thiab tsim cov khoom siv los nag, Niobium txhawb nqa cov hlau tshaj tawm los ntawm 20-30% thiab tensile lub zog los ntawm 15-25%tsis muajnce tuab lossis ntxiv cov khoom kim kim, piv txwv li, vanadium). Qhov no ua rau nws tseem ceeb rauSiab - muaj zog tsawg -} alloy (hsla) cov hlau, Siv rau kev teeb yuag tsis tau xws li cov ntawv thov ruaj khov xws li kev lag luam tsheb chassis, raj xa dej, thiab siv beams.
Txhim Kho Weldability: Coarse nplej hauv hlau tuaj yeem ua rau tawg thaum vuam. Niobium lub grain- Cov nyhuv ua kom zoo ua rau tsim cov nyhuv, ntau yam teeb tsa micrivedure, txo qhov kev pheej hmoo ntawm weld tsis meej. Qhov no yog qhov tshwj xeeb tshaj yog cov qauv sib txuas hauv cov choj lossis chaw nkaum platform, qhov twg Weld kev ncaj ncees tsis yog {sib yeem.
Corrosion Kuj: Niobium lub inertness nyob rau hauv oxidizing, acidic, thiab siab {-} Qhov chaw ib puag ncig Enhiat Enlosion. Piv txwv li, HSLA hlau nrog Niobium ua tau zoo dua hauv cov nroj tsuag lossis cov nroj tsuag ua haujlwm.
Tus Nqi Muaj Zog: Txawm tias me niobium ntxiv (0.05-0.15%) xa cov khoom tau zoo dua li siv cov ntsiab lus microalloying (piv txwv li, titanium lossis vanadium).
Hauv ntej, Niobium hloov cov hlau zoo li qub rau hauv lub zog, nruj dua, thiab ntau yam kev tsim kho, thiab cov tsheb thauj mus los, thiab lub zog tsheb loj.
Dab tsi yog siv ntawm ferroniobium alloy?
Ferroniobium (FENB), ib qho alloy ntawm hlau (FE) thiab Niobium (NB, yog ib qho tshwj xeeb ferrroalloy nrog cov khoom siv microalloying thiab nws cov khoom siv tshwj xeeb:
Steelmaking (thawj siv): Tshaj 90% ntawm ferrroniobium yog siv hauv cov hlau ua khoom. Ntxiv rau hauv cov khoom me me (0.05-0.15%) rau Molten hlau, nws yaj los tso Niobium atoms, uas ua rau NBC / NBN precipitates. Cov no ua kom cov hlau ua kom cov hlau lub noob qoob loo qauv, txhim kho lub zog, kev nyuaj, thiab weldability. Qhov no ua rau cov khoom siv HSla ntau lawm - tseem ceeb rau:
Kev tsa tsev: High -}}}}}}}} rise tsev, thiab pipelines (piv txwv, x70 roj av hlau).
Automotive: Hnav lub cev vaj huam sib luag thiab cov khoom siv muaj kev nyab xeeb (piv txwv li, tsoo}} tiv taus cov ntas).
Lub zog: Cua Turbine Yees thiab cov roj / roj ua kom zoo.
Superalloys rau high -} qhov kub siv: Ferrroniobium yog cov khoom tseem ceeb hauvNickel -} Raws supallloys(Piv txwv li, inconel 718), qhov chaw niobium cov ntaub ntawv nyuaj, cua sov-} - ni₃nb). Cov superalloys tau khaws lub zog ntawm kev nce kub (txog 700 degree) thiab siv nyob rau hauv:
Ib tug tub rog: JET LUB CAV TURNELLINE HNIAV THIAB ROCUMET CAV.
Lub Zog Loj: Roj turbine hniav tuaj hauv cov nroj tsuag fais fab.
Hluav taws xob thiab capacitors: Thaum ntshiab niobium siv nyob rau hauv capacitors, ferroniobium pabcuam ua cov khoom siv rawing rau kev ua niobium oxide (niobium hlau hmoov. Cov no yog qhov tseem ceeb rau:
Cov khoom - Lub Xeev Cap Capitors: Niobium oxide Dieleccide muaj kev muaj peev xwm siab thiab ruaj khov, siv hauv cov khoom siv hluav taws xob (piv txwv li, cov khoos phis tawj).
Vuam Electrodes: Ferrroniobium yog ntxiv rau vuam pas nrig los txhim kho weld da dej thiab txo kev sib tw. Lub fenined grees qauv ntawm weld hlau txhim kho thiab tawg tawm, ua rau nws tsim nyog rau cov qauv tseem ceeb hauv Welds.
Nuclear thiab aerospace alloys: Niobium lub radiation tsis kam (los ntawm ferrroniobium) ua rau nws muaj txiaj ntsig hauv Nuclear Reactor Cheebtsam. Ib qho ntxiv, nb {- ti alloys (derived los ntawm ferroniobium) tau siv nyob rau hauv cov hlau nplaum rau MRI thiab cov particle accelerators.
