1. Lub cev nqaij daim tawv
Ntawm cov hlau ntsiab, titanium muaj lub zog siab tshwj xeeb. Nws yog lub zog siab tab sis qis hlau zoo nrog cov ductility zoo (tshwj xeeb tshaj yog nyob rau hauv ib puag ncig oxygen tsis pub muaj). Qhov saum npoo ntawm titanium muaj cov nyiaj-dawb xim hlau lo lus. Nws lub taw tes melting yog siab heev (tshaj 1,649 degrees Celsius), yog li nws yog qhov zoo refractory cov khoom siv hlau. Nws yog paramagnetic, thiab nws cov hluav taws xob thiab thermal conductivity tsawg heev.
Kev lag luam qib titanium (kev coj dawb huv ntawm 99.2%) muaj qhov kawg tensile lub zog ntawm txog 434 megapascals, uas yog zoo li qib qis cov hlau tsis muaj zog, tab sis yog 45% sib zog dua li cov hlau alloys. Qhov ntom ntom ntawm titanium yog 60% siab dua li ntawm aluminium, tab sis nws lub zog yog ob zaug ntawm qhov ntau ntawm 6061-T6 aluminium alloy.
Titanium tuaj yeem siv rau ntau lub hom phiaj. Qee qhov alloys titanium (xws li βC) muaj lub zog tensile ntawm 1,400 megapascals. Txawm li cas los xij, thaum cov titanium raug rhaub mus rau saum toj no 430 degrees Celsius, nws lub zog txo qis.
Txawm hais tias tsis sib piv nrog high-qib tshav kub-kho cov hlau, titanium tseem muaj qhov nyuaj nyuaj. Titanium tsis muaj hlau nplaum, thiab nws kuj tseem ua hluav taws xob tsis zoo thiab ua rau hluav taws xob. Ua tib zoo mloog rau kev siv tshuab, vim hais tias yog tias cov cuab yeej ntse thiab cov kev coj ua kom txias tsis siv, titanium yuav muag muag thiab tawm indentations. Ib yam li cov qauv hlau, cov qauv titanium muaj cov kev ua kom tsis muaj zog, yog li nws tuaj yeem lav ua ruaj rau hauv qee daim ntawv thov.
Qhov tshwj xeeb tsis meej ntawm titanium alloy feem ntau tsis zoo dua li lwm cov ntaub ntawv xws li aluminium alloy thiab carbon fiber, yog li nws tsis tshua siv hauv cov qauv uas yuav tsum muaj txhav hnyav.
2. Cov khoom siv tshuaj
Ntawm cov yam ntxwv ntawm titanium, qhov tsim nyog tshaj yog nws txoj kev tiv thaiv zoo-nws corrosion kuj yuav luag zoo li platinum. Titanium tsis corroded los ntawm dilute sulfuric acid, dilute hydrochloric acid, chlorine gas, chlorine tov thiab feem ntau cov organic acids. Tab sis nws tseem tuaj yeem yuav yaj los ntawm cov kua qaub. Txawm hais tias daim duab cuam tshuam-pH hauv qab no qhia tau hais tias titanium yog cov hlau muaj cov yam ntxwv ua haujlwm kub, nws cov tshuaj tiv thaiv nrog dej thiab huab cua qeeb heev.
