Titanium yog ruaj khov heev nyob rau hauv huab cua ntawm chav tsev kub. Thaum rhuab mus rau {{0}} degree, muaj zog oxide zaj duab xis yog tsim rau saum npoo los tiv thaiv nws ntawm oxidation ntxiv. Titanium muaj peev xwm nqus tau oxygen, nitrogen, thiab hydrogen. Cov pa roj no muaj kev phom sij heev rau cov hlau titanium. Txawm tias tsawg heev (0.01% ~ 0.005%) tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab.
Ntawm cov titanium tebchaw, titanium dioxide (TiO2) muaj txiaj ntsig zoo tshaj plaws. TiO2 yog inert rau tib neeg lub cev thiab tsis muaj tshuaj lom. Nws muaj cov khoom siv kho qhov muag zoo heev. TiO2 yog opaque, muaj siab gloss thiab whiteness, siab refractive index thiab tawg lub zog, muaj zog npog lub hwj chim, thiab zoo dispersion. Cov xim uas tsim tawm yog cov hmoov dawb, feem ntau hu ua titanium dawb, uas yog siv dav. Cov tsos ntawm titanium rods zoo ib yam li cov hlau. Nws qhov ceev yog 4.51 g / cm2, uas yog tsawg dua 60% ntawm cov hlau. Nws yog cov khoom siv hlau nrog qhov ntom ntom ntawm cov hlau refractory. Cov khoom siv kho tshuab ntawm titanium, feem ntau hu ua cov khoom siv kho tshuab, muaj feem cuam tshuam rau purity. High-purity titanium muaj zoo machining zog, nrog zoo elongation thiab cheeb tsam txo, tab sis nws lub zog yog tsawg thiab nws tsis haum rau cov khoom siv. Kev lag luam ntshiab titanium muaj qhov nruab nrab ntawm impurities, muaj lub zog siab thiab plasticity, thiab tsim nyog rau kev tsim cov khoom siv.
Titanium alloystau muab faib ua lub zog qis thiab siab plasticity, nruab nrab lub zog thiab lub zog siab, xws li 200 (tsis muaj zog) mus rau 1300 (siab zog) MPa, tab sis feem ntau titanium alloys tuaj yeem suav tias yog cov khoom siv muaj zog. Lawv muaj zog dua aluminium alloys, uas yog suav hais tias yog nruab nrab-lub zog thiab tuaj yeem hloov tau qee hom hlau raws li lub zog. Piv nrog rau qhov txo qis hauv lub zog ntawm aluminium alloys ntawm qhov kub siab tshaj 150 degree, qee cov titanium alloys tseem tuaj yeem tuav lub zog zoo ntawm 600 degree. Dense Metallic titanium yog muaj txiaj ntsig los ntawm kev lag luam Aviation vim tias nws lub zog loj dua aluminium, thiab muaj peev xwm tswj hwm lub zog siab dua li txhuas thaum kub.
Vim tias qhov ceev ntawm titanium yog 57% steel, nws lub zog tshwj xeeb (lub zog / qhov hnyav piv lossis lub zog / qhov sib piv yog hu ua lub zog tshwj xeeb) yog siab, thiab nws cov kev tiv thaiv corrosion, tiv thaiv oxidation, thiab tiv thaiv kev qaug zog muaj zog. 3/4 ntawm titanium alloys yog siv los ua cov ntaub ntawv uas sawv cev los ntawm aerospace structural alloys, thiab 1/4 feem ntau yog siv los ua corrosion-resistant alloys. Titanium alloy muaj lub zog siab thiab qhov tsis tshua muaj zog, cov kws kho mob zoo, cov khoom siv zoo, thiab corrosion tsis kam. Tsis tas li ntawd, titanium alloys muaj cov txheej txheem tsis zoo thiab ua haujlwm nyuaj. Thaum lub sij hawm thermal ua, lawv yooj yim nqus impurities xws li hydrogen, oxygen, nitrogen, thiab carbon. Nws kuj muaj kev hnav tsis zoo thiab cov txheej txheem ntau lawm.
Kev tsim khoom ntawm titanium pib hauv xyoo 1948. Qhov kev xav tau ntawm kev tsim kho kev lag luam aviation tau ua rau kev lag luam titanium tsim los ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 8%. Tam sim no, lub ntiaj teb cov khoom tsim tawm txhua xyoo ntawm titanium alloy ua cov ntaub ntawv tau mus txog ntau dua 40, 000 tons, nrog ze li 30 hom titanium alloy qib. Feem ntau siv titanium alloys yog Ti-6Al-4V (Gr5), Ti-5Al-2.5Sn (Gr6), thiab muaj titanium ntshiab (Gr1, Gr2). , thiab Gr3).
Muaj peb txoj kev kho cua sov rau titanium rods thiab titanium alloy rods:
1) Cov khoom siv kho mob thiab kev laus: Lub hom phiaj yog txhawm rau txhim kho nws lub zog. Alpha titanium alloy thiab ruaj khov beta titanium alloy tsis tuaj yeem ntxiv dag zog thiab kho cua sov, thiab tsuas yog annealed thaum lub sijhawm tsim khoom. + titanium alloys thiab metastable titanium alloys uas muaj cov theem me me tuaj yeem ntxiv dag zog ntxiv los ntawm cov khoom siv kho mob thiab kev laus.
2) Stress relief annealing: Lub hom phiaj yog tshem tawm lossis txo cov kev ntxhov siab uas tshwm sim thaum ua haujlwm. Tiv thaiv tshuaj tua kab mob thiab txo qis deformation hauv qee qhov chaw corrosive.
3) Ua kom tiav annealing: Lub hom phiaj yog kom tau zoo toughness, txhim kho kev ua tau zoo, pab txhawb reprocessing, thiab txhim kho qhov seem thiab kev ruaj ntseg.
