Puas yog Niobium muaj zog dua titanium?

Puas yog Niobium muaj zog dua titanium?​

Cov lus teb nyob ntawm cov ntsiab lus ntawm "lub zog," ua ob qho tib neeg sib tw sib txawv nyob ntawm lawv daim foos (ntshiab vs. sib txuam) thiab kev ua tiav.

​Cov hlau ntshiab: Ntshiab titanium muaj lub zog tensile ntawm ~ 434 MPa, thaum koj lub zog dawb huv (NB) muaj lub zog qis (~ 200-400 MPa). Nyob rau hauv no unalloyed xeev, titanium feem ntau muaj zog dua niobium.

​LamOs: Niobium thiab titanium feem ntau yog sib txuam nrog lwm cov ntsiab lus los txhim kho lub zog. Piv txwv li:

Titanium alloys (piv txwv li, ti, 4v) ua tiav lub zog tensile li 900-1,200 MPa, leveraging aluminium thiab vanadium rau kev txhim kho kev ua tau zoo.

Niobium alloys (piv txwv li, nb - mpa}

Nyob rau hauv feem ntau cov ntawv thov, titanium alloys outperform pure niobium lub peev xwm nyob rau hauv nws muaj peev xwm los txhim kho lwm cov ntaub ntawv (piv txwv li ntau dua li kev sib tw ncaj qha raws li tus qauv sib tw.

 

Dab tsi yog qhov tseem ceeb siv ntawm niobium?​

Niobium thawj daim ntawv thov kev lag luam yog aMicroalloying caij hauv cov hlau lawm, Qhov twg nws tau ntxiv ua ferro niobium (ferroniobium, muaj 60-70% NB). Los ntawm kev ua kom zoo niobium carbides / piv txwv li, NBC, NBN kev txhim kho qauv, kev txhim kho steel, thiab weldability tsis muaj qhov hnyav. Qhov no ua rau nws tsis tseem ceeb rau high- muaj zog tsawg {{}} alloy (hsla) cov hlau, dav siv hauv:

Kev Siv (Txuas hniav, Pipelines).

Kev tsim khoom lag luam (chassis, Cheebtsam muaj kev nyab xeeb).

Hnyav cov tshuab hluav taws xob thiab lub zog hluav taws xob (cua tshuab hluav taws xob (cua tshuab, roj / roj roj).

Dhau ntawm cov hlau, niobium siv nyob rau hauv:

​Khoom nyiam tshaj lijRau cov dav hlau xyaw thiab roj av tshuab (piv txwv li, nb - ti alloys rau high- kub lub zog).

​Khoom siv hluav taws xob(Niobium oxide capacitors rau lub zog ruaj khov).

​Cov Khoom Siv Kho Mob(Niobium alloys rau tsis- restringe phais cov khoom).

 

​Lub teb chaws twg yog qhov loj tshaj plaws ntawm Niobium?​

Brazil yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws ntawm Niobium, suav rau ntau tshaj 90% ntawm cov zis thoob ntiaj teb. Feem ntau ntawm Brazil ntau lawm los ntawm covAraxy mine(Ua haujlwm los ntawm CBMM, cov tuam txhab Brasileira de Hlauhurgia E Mineração), nyob hauv Minas Gerais. Qhov no kuv tuav cov loj tshaj plaws niobium muaj peev xwm tshwj xeeb hauv ntiaj teb (~ 150 lab tons ntawm muaj niobium).

Lwm cov neeg tsim khoom tseem ceeb muaj xws li:

Canada (piv txwv li, niobec mine hauv quebec).

Australia (me - cov haujlwm ua haujlwm).

Nigeria thiab Rwanda (tawm cov neeg tsim khoom nrog kev tsim tawm zuj zus).

Brazil lub dominance stems los ntawm nws loj heev, siab}} {{{1} {{1}- Kev Lag Luam Kev Lag Luam Hauv Ntiaj Teb thiab Advanced Manufacturies.
