Titanium yog ruaj khov heev nyob rau hauv huab cua ntawm chav tsev kub. Thaum rhuab mus rau {{0}} degree, ib qho khoom oxide zaj duab xis yog tsim rau ntawm qhov chaw, muab kev tiv thaiv tiv thaiv ntxiv oxidation. Titanium muaj peev xwm nqus tau oxygen, nitrogen, thiab hydrogen. Cov pa roj no muaj kev phom sij heev rau cov hlau titanium, thiab txawm tias me me (0.01 feem pua rau 0.005 feem pua), lawv 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 thiab tsis muaj tshuaj lom rau tib neeg lub cev, thiab nws muaj cov khoom siv kho qhov muag zoo heev. TiO2 yog opaque, nrog siab glossiness thiab whiteness, siab refractive Performance index thiab tawg lub zog, muaj zog npog lub hwj chim, thiab zoo dispersibility. Cov xim uas tsim tawm yog cov hmoov dawb, feem ntau hu ua titanium dawb, uas yog siv dav. Cov tsos ntawm titanium pas nrig yog zoo ib yam li cov hlau, nrog ib tug ceev ntawm 4.51g / cm3, uas yog tsawg tshaj li 60 feem pua ntawm cov hlau. Nws yog qhov tsawg tshaj plaws hlau qhov chaw ntawm refractory hlau. Cov khoom siv kho tshuab ntawm titanium, feem ntau hu ua nws cov khoom siv kho tshuab, muaj feem cuam tshuam nrog nws cov purity. High purity titanium muaj kev ua haujlwm zoo heev, zoo heev elongation thiab hla ntu ntu, tab sis tsis muaj zog, ua rau nws tsis haum rau kev siv los ua cov khoom siv. Muaj cov ntshiab titanium muaj qhov tsim nyog ntawm impurities, muaj lub zog siab thiab plasticity, thiab tsim nyog rau kev tsim cov khoom siv.
Titanium alloys tuaj yeem muab faib ua lub zog qis, siab plasticity, nruab nrab lub zog, thiab lub zog siab, xws li 200 (tsis muaj zog) txog 1300 (siab zog) megapascals. Txawm li cas los xij, titanium alloys feem ntau tuaj yeem suav hais tias yog cov hlau muaj zog. Lawv muaj lub zog siab dua li aluminium alloys suav tias yog lub zog nruab nrab, thiab tuaj yeem hloov pauv qee yam ntawm cov 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. Tuab cov hlau titanium tau txais siab los ntawm kev lag luam Aviation vim nws lub zog loj dua li txhuas alloy, thiab muaj peev xwm tswj hwm lub zog siab dua li txhuas thaum kub. Xav tias qhov ceev ntawm titanium yog 57 feem pua ntawm cov hlau, nws lub zog tshwj xeeb (lub zog / qhov hnyav piv lossis lub zog / qhov sib piv yog ob qho tib si hu ua lub zog tshwj xeeb) yog siab, thiab nws cov corrosion kuj, oxidation tsis kam, thiab qaug zog kuj yog tag nrho cov muaj zog. . 3/4 ntawm titanium alloys yog siv los ua cov ntaub ntawv uas sawv cev los ntawm aviation structural alloys, thiab 1/4 feem ntau yog siv los ua corrosion-resistant alloys. Titanium alloy muaj lub zog siab thiab qhov ntom ntom, cov khoom siv zoo, zoo toughness thiab corrosion kuj. Tsis tas li ntawd, titanium alloys muaj kev ua haujlwm tsis zoo thiab nyuaj rau kev txiav. Hauv kev ua haujlwm kub, nws yooj yim heev rau nqus cov impurities xws li hydrogen, oxygen, nitrogen thiab carbon. Kuj tseem muaj kev hnav tsis zoo thiab cov txheej txheem ntau lawm. Kev lag luam tsim khoom ntawm titanium pib xyoo 1948. Txoj kev loj hlob ntawm kev lag luam aviation yuav tsum muaj kev lag luam titanium loj hlob ntawm qhov nruab nrab txhua xyoo ntawm kwv yees li 8 feem pua. Tam sim no, txhua xyoo ntawm titanium alloy ua cov ntaub ntawv nyob rau hauv lub ntiaj teb no tau mus txog ntau tshaj 40000 tons, nrog ze li ntawm 30 titanium alloy qib. Feem ntau siv titanium alloys yog Ti-6Al-4V (TC4) 'Ti-5Al-2.5Sn (TA7) thiab industrial ntshiab titanium (TA1, TA2, thiab TA3).
