Titanium alloy yog silvery dawb thiab ci, nyob rau hauv qeb 22 nyob rau hauv lub sij hawm lub sij hawm, thiab nws tus kheej cov khoom muaj zog heev. Yog tias koj xav yaj titanium, koj xav tau qhov kub thiab txias ntawm 1 662 degrees Celsius, titanium yog ib pab pawg ntawm cov hlau melting point nyob rau hauv lub teeb kub domain, nrog siab hardness, tensile zog ntawm 1 800 n / mm2, thiab muaj zog plasticity. Titanium muaj qhov ceev ntawm 4.54 g / cc. Nyob rau hauv chav tsev kub, titanium yog ib tug kaw-packed hexagonal theem uas tsis muaj kub. Ntawm 885 degree C, titanium hloov mus rau hauv lub cev-centered cubic theem.
Raws li cov khoom, titanium alloys tau muab faib ua corrosion-resistant titanium alloys, tshav kub-resistant titanium alloys, low-temperature titanium alloys, thiab high-strength titanium alloys, ntawm cov high-strength titanium alloys yog muab faib mus rau hauv siab zog titanium alloys. , siab zog thiab kub kub titanium alloys thiab siab zog steel titanium alloys.
Titanium thiab titanium alloys muaj lub zog siab thiab lub zog tshwj xeeb, zoo corrosion kuj, thiab kev ua haujlwm siab thiab qis qis; Titanium thiab titanium alloys tsis sib nqus, nyob rau hauv ib tug muaj zog magnetic teb yuav tsis magnetized; Qee cov titanium alloys muaj qee cov khoom tshwj xeeb, xws li Ti2Ni alloy yog cov khoom siv zoo nco, thiab Nb2Ti alloy yog cov khoom siv kub-kub superconducting.
Titanium thiab titanium alloys tau siv dav hauv kev lag luam aerospace, roj av, tshuaj T., metallurgy, tshuaj lom neeg, khoom ua si, thiab lwm yam, thiab tau dhau los ua cov khoom siv hlau tsis tseem ceeb rau cov cuab yeej tshiab, thev naus laus zis tshiab, thiab cov cuab yeej tshiab. .
1, Lub zog loj, qhov ceev ntawm titanium alloy feem ntau yog li 4.51g / cubic centimeter, tsuas yog 60 feem pua ntawm cov hlau, qhov ceev ntawm cov titanium ntshiab yog ze rau qhov ntom ntawm cov hlau zoo tib yam, qee qhov siab zog titanium alloy tshaj lub zog ntawm ntau alloy. steel qauv.
2, Lub zog thermal muaj zog, kev siv qhov kub thiab txias yog ntau pua degrees siab dua aluminium alloy, ntawm qhov nruab nrab kub tseem tuaj yeem tuav lub zog uas yuav tsum tau ua, tuaj yeem ua haujlwm hauv 450 ~ 500 degree kub rau lub sijhawm ntev ob hom titanium alloy nyob rau hauv qhov ntau. ntawm 150 degree ~ 500 degree tseem muaj lub zog tshwj xeeb, thiab aluminium alloy ntawm 150 degree dua li lub zog poob qis. Kev ua haujlwm kub ntawm titanium alloy tuaj yeem ncav cuag 500 degree, thiab cov aluminium alloy yog qis dua 200 degree.
3, Zoo corrosion kuj, titanium alloy ua hauj lwm nyob rau hauv cov huab cua ntub thiab seawater nruab nrab, nws corrosion kuj yog deb zoo dua stainless hlau; Kev tiv thaiv rau pitting corrosion, acid corrosion, thiab kev nyuaj siab corrosion yog tshwj xeeb tshaj yog muaj zog; Zoo heev corrosion kuj rau alkali, chloride, chlorine organic khoom, nitric acid, sulfuric acid thiab hais txog. Tab sis titanium muaj qhov tsis zoo corrosion los txo cov pa oxygen thiab chromite nruab nrab.
4, Kev ua haujlwm kub qis yog qhov zoo, titanium alloy ntawm qhov kub thiab txias tsis tshua muaj peev xwm tseem tuaj yeem tuav nws cov khoom siv kho tshuab. Titanium alloys nrog kev ua tau zoo ntawm qhov kub thiab txias heev, xws li TA7, tuaj yeem tswj tau qee yam plasticity ntawm -253 degree . Yog li ntawd, titanium alloy kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob qis.
5, tshuaj lom neeg kev ua si, tshuaj lom neeg kev ua si ntawm titanium yog loj, thiab cov huab cua O, N, H, CO, CO2, dej vapor, ammonia, thiab lwm yam muaj zog tshuaj tiv thaiv.
6, thermal conductivity ntawm me me, thermal conductivity ntawm titanium λ=15.24W / (mK) yog hais txog 1/4 ntawm nickel, 1/5 ntawm hlau, 1/14 ntawm txhuas, thiab thermal conductivity ntawm Ntau yam titanium alloys tshaj qhov thermal conductivity ntawm titanium poob li 50 feem pua.
