Dab tsi yog cov yam ntxwv ntawm titanium thiab titanium alloys?
Titanium tshav kub tsis kam
aluminium poob nws cov khoom tshwj xeeb ntawm 150 degree, tempered steel poob nws cov khoom tshwj xeeb ntawm 310 degree, thiab titanium composites ua tau zoo nrog cov khoom siv zoo ntawm ib puag ncig 500 ~ 600 degree. Nyob rau ntawm lub sijhawm thaum lub dav hlau ceev tuaj txog ntawm Mach 2.7, qhov kub thiab txias ntawm lub dav hlau qauv tuaj txog 230 degree. Titanium alloys tuaj yeem ua tau raws li qhov yuav tsum tau ua, tab sis magnesium alloys thiab aluminium alloys tsis muaj lawm. Titanium yog siv nyob rau hauv aircraft engine compressor disks thiab hniav raws li zoo raws li daim tawv nqaij ntawm rear fuselages vim nws zoo heev kub kuj.
Tsawg kub khoom ntawm titanium
Lub zog ntawm qee cov titanium tebchaw, (piv txwv li, Ti-5Al-2.5SnELI) nce raws li qhov kub thiab txias, tab sis lub plliancy tsis ploj zuj zus ntau. Nws yeej muaj ntau yam zoo thiab muaj zog ntawm qhov kub thiab txias thiab tsim nyog rau kev siv ntawm qhov kub thiab txias. Nws tuaj yeem siv tau rau hauv cov foob pob hluav taws uas hlawv cov pa oxygen thiab hydrogen, nrog rau ultra-low-temperature cia tso tsheb hlau luam thiab ntim rau ntawm lub dav hlau manned.
Titanium cov khoom sib nqus thiab kev siv Titanium nws tus kheej tsis yog hlau nplaum, thiab titanium alloys ua tsis muaj hlau kuj tsis sib nqus. Yog li ntawd, sib nqus cuam tshuam tuaj yeem zam tau zoo. Siv rau submarine plhaub thiab yuav tsis ua rau kuv blasts. Raws li kev siv hauv kev tiv thaiv pej xeem, ya corps, thiab riam phom fabricating, nws tseem yog feem ntau siv nyob rau hauv rail kab tsim, correspondences, aviation, aeronautics, super advanced labs, chaw kho mob xwm txheej ceev (filters, X-beams, txaus nyiam reverberation duab, electrocardiograms. , cathode beam raj), tshuaj, atomic Industry, atomic txaus nyiam reverberation, txaus nyiam spectrometer, siab Tesla hlau nplaum, sab nraum cov dej num, moor kev loj hlob, plunging, compound kev lag luam, tua kev ruaj ntseg, desalination, shipbuilding, seaward roj thiab roj theem, ntsev kev lag luam, thiab yog li ntawd.
Sov conductivity ntawm titanium
Qhov sov sov conductivity ntawm titanium ua ke yog me ntsis, uas yog hais tias, nws warms li sai thiab ua cua sov maj mam. Nws cov thermal conductivity tsuas yog 1/5 ntawm cov hlau, 1/13 ntawm txhuas, thiab 1/25 ntawm tooj liab. Hmoov tsis zoo yog qhov tsis zoo ntawm titanium, txawm li cas los xij cov cuab yeej ntawm titanium tuaj yeem raug coj los siv rau lub sijhawm.
Modulus ntawm elasticity ntawm titanium
Titanium ntau yam modulus tsuas yog ib feem ntawm cov hlau. Vim nws tsis tshua muaj elastic modulus thiab susceptibility rau deflection, nws yog unsuitable rau cov qauv siv.
Titanium yield zog thiab tensile lub zog Lub Ti-6Al-4V titanium alloy muaj lub zog tawm los ntawm 892 MPa thiab lub zog tensile ntawm 960 MPa. Qhov sib piv ntawm ob yog tsuas yog 58MPa. Cov cim lag luam no ua rau titanium tsim lub caij nplooj ntoo hlav loj thaum tuav, uas yuav tsum muaj sia nyob.
Cov xwm txheej ntawm titanium ntawm qhov kub thiab txias
Titanium muaj lub zog loj rau lub zog nrog hydrogen thiab oxygen. Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj oxidation thiab hydrogen retention. Titanium vuam yuav tsum tau ua nyob rau hauv argon kev ruaj ntseg rau forestall muaj kuab paug. Titanium cylinders thiab daim hlau yuav tsum tau kho cua sov hauv lub tshuab nqus tsev, thiab cov cua oxidation me me yuav tsum tau tswj xyuas thaum tshav kub kub ntawm titanium forgings.
Anti-damping zog ntawm titanium thiab nws siv
Cov sijhawm tsis sib xws hauv cov duab thiab qhov loj me yog ua los ntawm titanium thiab lwm yam khoom siv hlau (tooj liab, hlau). Peb pom tau hais tias thaum ntau lub tswb nrov titanium raug ntaus nrog tib lub zog, lub suab tau ntev dua thaum lub tswb nrov titanium oscillated, qhia tias titanium muaj zog qis dua thiab tuaj yeem siv los ua ntau yam twj paj nruag.
Peb lub luag haujlwm tshwj xeeb ntawm titanium thiab titanium alloys
Titanium lub cim xeeb muaj peev xwm, superconducting muaj peev xwm thiab hydrogen assimilation muaj peev xwm hu ua peb lub ntsiab tshwj xeeb ntawm titanium thiab titanium amalgams.
Titanium zoo lub cim xeeb muaj peev xwm
Ib qho tshwj xeeb ntawm Ti-Ni sib xyaw tuaj yeem rov tsim kho nws cov duab tshwj xeeb hauv cov xwm txheej kub tshwj xeeb, lossis tsawg kawg, nws muaj peev xwm nco tau. Cov khoom no yog lub npe hu ua lub cim xeeb sib xyaw. Niaj hnub no, cov duab nco ua ke feem ntau yog siv hauv aviation, marine, riam phom, kev kho mob thiab kev siv niaj hnub no.
Superconducting zog ntawm titanium
Nyob rau ntawm qhov chaw thaum qhov kub thiab txias txo mus rau zero, cov xov hlau uas tsim los ntawm niobium-titanium compound poob kev cuam tshuam thiab ua superconducting. Thaum lub sij hawm ib tug loj heev tam sim no mus, cov hlau yuav tsis sov thiab tsis muaj zog. Nb-Ti yog lub npe hu ua cov khoom siv superconducting.
Titanium's hydrogen absorption muaj nuj nqi
Ib qho tshwj xeeb ntawm Ti-Fe sib xyaw tuaj yeem noj ntau cov hydrogen. Siv cov cim kev lag luam no, hydrogen tuaj yeem muab pov tseg kom ruaj ntseg, thiab nyob rau hauv cov xwm txheej tshwj xeeb, Ti-Fe muaj peev xwm siv tau los xa cov hydrogen, uas muab cov kev xaiv sib piv rau kev siv steel hi.
