Titanium Alloy Qib: Ib qho kev piav qhia ntawm plaub yam tseem ceeb
Muaj ntau tshaj 100 titanium alloy qib raws li cov ntaub ntawv, tab sis tsuas yog ib lub kaum os los yog li ntawd yeej siv industrially. Txawm li cas los xij, cov qib no nyuaj rau nco ntsoov kom meej, yog li metallurgists faib lawv los ntawm lawv cov microstructure.
Titanium Alloy Classification
Raws li kev hloov pauv hauv microstructure, titanium alloys tau muab faib ua plaub hom: - hom, ze - - hom, + - hom, thiab - hom titanium alloys.
Ntshiab titanium tau dhau los ua cov qauv siv lead ua hloov ntawm kwv yees li 882 degree. Hauv qab no qhov kub thiab txias, titanium muaj hexagonal kaw -packed (HCP) qauv, hu ua theem. Thaum kub dua, nws hloov mus rau hauv lub cev -centered cubic (BCC) qauv, hu ua theem. Alloying cov ntsiab lus cuam tshuam cov ntsiab lus ntawm cov theem los yog theem ntawm chav tsev kub. Aluminium, oxygen, thiab nitrogen feem ntau ruaj khov rau theem, thaum cov khoom xws li vanadium, molybdenum, chromium, thiab niobium zoo li stabilize theem, ua rau lub ntsiab titanium alloy series. Peb kuj tuaj yeem nkag siab txog kev hloov pauv ntawm cov qauv hauv qab no: → ze - → + → . Nrog rau cov qauv kev hloov pauv no, cov khoom xws li lub zog, ductility, kub tsis kam, formability, thiab kev kho cua sov teb kuj hloov.
Titanium alloys
Feem ntau pom cov alloys TA0, TA1, TA2, TA3, TA7, TA9, thiab TA10 yog cov feem ntau muaj cov ntshiab titanium alloys, kuj siv nyob rau hauv daim ntaub ntawv uas yuav tsum tau tshwj xeeb tshaj yog corrosion kuj. Cov alloys no tsis raug xaiv rau lawv lub zog siab heev; lawv zoo heev corrosion kuj, zoo weldability, thiab kuj zoo machinability yog lawv qhov zoo. Yog li ntawd, lawv feem ntau siv rau hauv cov khoom siv tshuaj, cov khoom siv hluav taws xob, cov kav dej, cov khoom siv petrochemical, cov khoom siv chlor-alkali, thiab cov dej kho dej. Rau cov khoom siv raug corrosive media, siab tensile lub zog yog qhov zoo dua li titanium corrosion kuj.
Nyob ze - Titanium Alloys
Ze ntawm - alloys feem ntau yog tsim los ntawm theem, muaj me me ntawm theem. Qib suav nrog TA11, TA15, TA13, thiab TA19. Piv nrog rau cov alloys zoo tib yam, cov ntaub ntawv no pom tau hais tias muaj zog siab tshaj - kub lub zog thiab nkag mus. Cov no feem ntau yog siv hauv cov qauv hauv aerospace thiab cav-cov khoom muaj feem xyuam. Piv txwv li, TA15, tseem hu ua BT20, thiab TA19, sib xws rau Ti-6242S, muab kev ua tau zoo dua qub. Lawv cov khoom txhim kho lub zog ntawm titanium ntawm chav tsev kub thaum tswj nws qhov kev ua tau zoo tshaj lub sijhawm ntev ntawm qhov kub thiab txias.
+ Titanium alloys
Cov hom alloy feem ntau muaj xws li TC1, TC4, TC6, TC10, thiab TC11. Peb yuav tsom mus rau TC4, vim nws yog qhov kev kawm ntau tshaj plaws, ntev tshaj plaws - siv, zoo tshaj - ua tau zoo, thiab feem ntau siv alloy. TC4 tus qauv tshuaj yog Ti-6Al-4V, thiab nws yog lub npe hu ua Qib 5 titanium. Nws muaj pes tsawg leeg suav nrog kwv yees li 6% txhuas thiab 4% vanadium.
+ titanium alloys tuaj yeem nyuaj rau vuam thiab tshuab. Qhov kawg kev ua tau zoo yog txiav txim siab los ntawm cov txheej txheem machining, kev kho cua sov, thiab cov khoom siv. + titanium alloys tuaj yeem nyuaj rau vuam thiab tshuab.
Titanium alloys
titanium alloys muaj feem ntau dua ntawm -stabilizing ntsiab. Piv txwv li, TB2, Beta C, thiab lwm yam metastable alloys. Cov yam ntxwv tseem ceeb ntawm cov ntaub ntawv no yog lawv cov formability. Hauv kev daws teeb meem -kho lub xeev, qee cov alloys kuj yooj yim rau txias- daim ntawv. Lawv lub zog tuaj yeem txhim kho tau zoo tom qab kev laus. Rau qee qib, lub zog tensile tuaj yeem ncav cuag 1300-1400 MPa, nyob ntawm seb muaj pes tsawg leeg, kev siv tshuab, thiab kev kho cua sov. Qhov no ua rau titanium alloys txaus nyiam nyob rau hauv cov teb xws li springs, fasteners, aerospace Cheebtsam, thiab cov khoom siv roj thiab roj. alloys feem ntau kim dua, thiab lawv cov khoom yog rhiab heev rau kev siv tshuab thiab kev kho cua sov. Lawv tsis tsuas yog "muaj zog" versions ntawm TC4.
Xaiv txoj cai Titanium Alloy rau Koj Kev Lag Luam
Thaum xaiv ib qho haum titanium alloy, yam xws li zoo corrosion kuj yuav ua rau alloys haum dua. Rau siab - kub daim ntawv thov, + alloys (xws li TC4) muab zoo ua ke lub zog thiab toughness, ua rau lawv feem ntau siv titanium alloys. alloys yog ib qho tseem ceeb tshwj xeeb rau lub zog siab, txias formability, los yog cov khoom kho cua sov tshwj xeeb.
Kev ceev faj rau kev siv Xuze titanium alloys:
Ib puag ncig rau kev siv
Yuav tsum muaj zog
Kev ua thiab tsim cov txheej txheem
Vuam thiab kev kho cua sov

Tom qab ntawd koj yuav tau paub txog "thawj lub hauv paus" ntawm titanium alloy xaiv: Rau corrosion kuj thiab zoo weldability, xaiv; rau qhov kub thiab txias, xaiv ze - ; rau kev ua tau zoo, xaiv + (TC4 ua thaub qab); rau kev sib sau txias thiab ultra-siab zog, xaiv
