Vim li cas Zirconium Ntxiv rau Niobium?

Ntshiab niobium yog dav siv nyob rau hauv siab -kub daim ntaub ntawv vim hais tias ntawm nws zoo heev ductility, zoo workability, thiab kuj tsis tshua muaj ceev ntawm refractory hlau.

Thaum cov neeg yuav khoom thawj zaug ntsib Nb-Zr alloy, ib lo lus nug tshwm sim:

Yog tias ntshiab niobium twb ua tau zoo ntawm qhov kub siab, vim li cas ntxiv zirconium?

Cov lus teb yog ze ze rau kev ua haujlwm ntev -. Raws li kev ua haujlwm kub nce thiab lub sijhawm ua haujlwm ntev dua, kev tswj xyuas lub zog thiab qhov ruaj khov ntawm qhov yuav tsum yog qhov tseem ceeb dua. Qhov no yog qhov twg zirconium muab tus nqi ntxiv.

Ntshiab niobium ua tau zoo nyob rau hauv ntau qhov chaw, tab sis qee qhov kev thov tso cai ntau dua rau cov khoom siv.

Cheebtsam siv nyob rau hauv siab -kub tshuab feem ntau yuav tsum tau nyob ruaj khov rau ncua sij hawm thaum raug mus tas li thermal loads. Nyob rau hauv cov xwm txheej no, kev tuav lub zog tuaj yeem ua ib qho tseem ceeb xws li qhov kub thiab txias.

Ib qho me me zirconium ntxiv pab txhim kho siab - qhov kub thiab txias zog thiab tiv thaiv kom nkag mus deformation. Rau cov neeg tsim qauv thiab cov kws tsim qauv, qhov no txhais tau hais tias cov khoom siv tau zoo tuaj yeem tswj tau lawv cov duab thiab kev ua tau zoo thaum lub sijhawm ua haujlwm ntev.

Qhov no yog ib qho ntawm cov laj thawj tseem ceeb Nb-Zr alloy feem ntau xaiv rau kev thov rau kev siv thermal.

Nb-Zr alloy feem ntau pom muaj nyob rau hauv daim ntawv thov uas yuav tsum tau muaj ob qho tib si kub thiab kev ntseeg tau.Cov piv txwv muaj xws li:

• Aerospace Cheebtsam
• Rocket propulsion systems
• Lub tshuab nqus tsev vacuum sib dhos
• Cov cuab yeej tshawb fawb tshawb fawb
• High -cov cuab yeej sim ntsuas kub

Kev xaiv cov khoom siv hauv cov kev lag luam no feem ntau yog nyob ntawm kev ua haujlwm ntev - lub sijhawm ua haujlwm tsis yog qhov ntsuas kub ib leeg. Kev ruaj ntseg thaum ua haujlwm yog qhov kev txiav txim siab loj.

Ntawm cov qib muaj, Nb-1Zr yog ib qho ntawm feem ntau.

Cov ntsiab lus zirconium yog qhov tsawg, tab sis kev txhim kho hauv kev ua tau zoo txaus rau ntau yam kev lag luam thiab kev tshawb fawb. Nyob rau tib lub sijhawm, cov khoom khaws cia cov yam ntxwv zoo, ua rau nws tsim nyog rau kev tsim cov pas nrig, cov ntawv, cov raj, xaim, thiab kev cai - cov khoom siv tshuab.

Rau ntau qhov project, Nb-1Zr muaj qhov sib npaug ntawm kev ua tau zoo thiab kev tsim khoom.

Tsis tas li.

Kev xaiv cov khoom nyob ntawm ntau yam, suav nrog kev ua haujlwm kub, kev xav tau ntawm txhua yam, txoj kev tsim, thiab kev pabcuam.

Cov ntsiab lus zirconium siab dua tsis tuaj yeem ua rau cov hlau zoo dua rau txhua daim ntawv thov. Engineers feem ntau tsom rau kev sib piv cov hlau rau qhov chaw ua haujlwm es tsis yog xaiv cov ntsiab lus siab tshaj plaws ntawm cov hlau muaj.

Thaum muas niobium zirconium alloy khoom, qhov ntev thiab tus nqi feem ntau yog thawj qhov kev tshuaj xyuas.Lwm yam tseem ceeb sib npaug:

• Alloy qib
• Zirconium cov ntsiab lus
• Khoom siv purity
• Cov txheej txheem ntau lawm
• Kev tshuaj ntsuam xyuas
• Deg mob
• Dimensional kam rau ua

Kev tshuaj xyuas cov ntsiab lus no ua ntej kev txiav txim tuaj yeem pab txo cov teeb meem kev tsim khoom thiab txhim kho qhov sib xws thaum lub sijhawm tsim khoom.

Zirconium ntxiv rau niobium txhawm rau txhim kho kev ua haujlwm hauv cov ntawv thov uas cov niobium ntshiab yuav ntsib kev xav tau ntau dua thaum lub sijhawm.

Txhim kho lub zog tuav, zoo dua tiv thaiv deformation, thiab txhim khu kev ruaj ntseg ntawm qhov kub siab yog vim li cas Nb-Zr alloy tseem siv rau hauv aerospace, nqus tsev, kev tshawb fawb, thiab lwm yam kev lag luam tshwj xeeb.

Rau ntau qhov kev siv kub - kub, lub hom phiaj tsis yog tsuas yog tiv taus cua sov, tab sis kom muaj kev ntseeg tau zoo thoob plaws hauv lub neej kev pab cuam ntawm cov khoom. Qhov ntawd yog qhov uas Nb-Zr alloy feem ntau muab qhov zoo dua niobium ntshiab.
