Qhov laj thawj vim li cas titanium xaim muaj lub zog siab
Nyob rau hauv lub Arena ntawm niaj hnub cov ntaub ntawv kev kawm txuj ci, Titanium cov hlau sawv tawm raws li cov khoom siv "hnub qub" vim nws muaj kev kawm tshwj xeeb. Ntawm cov khoom no, lub zog yog undoubtedly ib qho ntawm cov yam ntxwv tshaj plaws ntawm titanium hlau. Nws tsis tsuas yog txiav txim siab cov khoom siv thauj khoom-coj tau muaj peev xwm tab sis kuj cuam tshuam nrog kev siv tshuab hluav taws xob thiab cov khoom siv thev naus laus zis, khoom siv kho mob, thiab khoom siv kis las. Yog li, dab tsi yog lub zog ntawm titanium xaim, thiab dab tsi modience mysteries dag qab nws?
Lub zog yog lub peev xwm ntawm cov khoom siv los tiv thaiv deformation thiab tsis ua tiav nyob rau sab nraud rog, feem ntau ntsuas los ntawm kev ntxhov siab ntau. Rau Titanium hlau, nws lub siab-zog cov khoom lag luam los ntawm nws cov qauv siv lead ua kom zoo nkauj thiab microstructure. Titanium muaj ob pawg: hauv qab 882.5 degree, nws muaj nyob rau hauv hexagonal kaw-ntim kaw-ntim qauv (-ti). Cov qauv qauv no muaj cov txheej txheem ua kom nruj, tso cov khoom siv nrog cov khoom siab-kub ua rau muaj zog thiab zoo heev corrosion. Saum toj no 882.5 degree, nws hloov mus rau hauv lub cev-nruab nrab cov qauv sau lo lus teb (-ti), uas muab cov khoom siv zoo thiab ua haujlwm thaum muaj qhov kub. Hauv kev tsim tawm tiag tiag, los ntawm kev tswj hwm kev siv thev naus laus zis thiab kev kho cua sov ntawm tit-36ase tuaj yeem hloov kho qhov tseeb ntawm lub zog thiab tawv.
Lub zog ntawm cov ntshiab titanium yog qhov tsawg tsawg, tab sis nws muaj peev xwm zoo rau kev siv. Ntxiv cov alloy cov ntsiab xws li txhuas, Moladium, molybdenum, thiab tin rau titanium tuaj yeem txhim kho lub zog ntawm titanium hlau. Siv cov ti -6 AL -4 v alloy ua ib qho piv txwv. Qhov sib ntxiv ntawm txhuas tuaj yeem tswj cov -phase thiab ua si lub luag haujlwm hauv cov teeb meem kev daws teeb meem, thaum vanadium tuaj yeem tswj cov -Phase. Cov nyhuv sib xyaw ua ke ntawm ob leeg ua rau lub zog tensile ntawm Ti {}} v titanium hlau kom mus txog {}} mpa} Ua tsaug rau qhov kev kub siab no, ti {{}} v titanium xaub ntawm aerospace tshuab, xws li tuaj yeem siv los, thiab cov dav hlau. Nws kom ntseeg tau tias cov qauv tuaj yeem tiv thaiv kev ntxhov siab nyob rau hauv kev mob siab thaum txo qhov hnyav.
Ntxiv nrog rau tag nrho cov tshuab muaj pes tsawg leeg, kev siv tshuab ua cov tshuab kuj tseem muaj qhov cuam tshuam tseem ceeb ntawm lub zog ntawm titanium hlau. Cov txheej txheem ua haujlwm txias, xws li kos duab thiab dov, ua rau muaj kev cuam tshuam dislocation, ua rau muaj kev ua haujlwm rau lub zog titanium thiab ua rau nws lub zog titchabing. Txawm li cas los xij, kev ua haujlwm txias ntau dhau yuav txo cov khoom siv hloov pauv. Yog li ntawd, kev kho kom tsim nyog rau kev kho kom tsim nyog yuav tsum tau kho kom yooj yim thaum tswj lub zog siab. Cov txheej txheem ua haujlwm kub, xws li kos duab kub thiab kub forging, kho cov qauv zeb los ntawm kev rov ua dua tshiab dynamic. Lub ntsej muag zoo grav qauv tsis tsuas yog txhim kho lub zog tab sis kuj txhim kho kev ua tau zoo thiab qaug zog ntawm lub titanium hlau. Ntxiv mus, kev kho cov txheej txheem saum npoo zoo li kev tua cov nqaij nyuj muaj peev xwm ua kom paub cov khoom lag luam valanium, ua kom zoo dua kev txhim kho nws lub zog qaug zog.
Lub siab-zog muaj zog ntawm titanium hlau ua rau nws ua haujlwm irreplacleable hauv ntau thaj teb. Hauv cov cuab yeej kho mob ntaus ntawv, Titanium hlau siv rau kev tsim cov tuam tsev yuav tsum muaj lub zog tsis tshua muaj zog thiab biocompatibility. Txij li thaum muaj stent xav txhawb cov hlab ntshav tau ntev, muaj kev ntxhov siab rau cov ntshav siab thiab tsis muaj peev xwm tswj cov hlab ntsha Hauv cov khoom siv kis las, cov khoom lag luam xws li cov koom haum ntaus golf thiab cov tsheb kauj vab muaj qhov yuav tsum tau ua rau lub zog ntawm cov khoom siv. Nrog rau qhov zoo ntawm lub zog siab thiab qhov ntom ntom ntom ntom thiab titanium xaim tuaj yeem ua kom lub zog thiab ua haujlwm txo qis tag nrho cov neeg ncaws pob.
Txawm hais tias muaj lub zog zoo ua tau zoo ntawm titanium xaim, nws tseem fim cov kev sib tw hauv cov ntawv thov kev siv. Piv txwv li, hauv qhov chaw siab-ib puag ncig, lub zog ntawm titanium hlau tsawg zuj zus raws li qhov kub nce siab. Hauv qee cov xov xwm corrosive, txawm hais tias titanium muaj cov khoom lag luam tsis zoo, ib cheeb tsam ib puag ncig tseem tuaj yeem ua rau cov pob txha corrosion lossis kev ntxhov siab corrosion. Ib qho ntxiv, kev tsim tus nqi ntau lawm ntawm Titanium hlau yog qhov tseem ceeb, thiab ua cov thev naus laus zis ua lag luam thiab cov txheej txheem alloying rau nws cov ntawv thov. Nyob rau yav tom ntej, nrog rau kev txhim kho cov ntaub ntawv kev tshawb fawb, los ntawm kev tsim kho cov hlau hluavtaws tshiab, thiab nthuav dav nws cov chaw tsim khoom tshiab hauv cov chaw tsim khoom thiab cov khoom lag luam siab.
Los ntawm cov ntawv me me crystal rau macroscopic engineering engineering cov khoom siv ntawm titanium xaim yog cov qauv ntawm cov khoom siv science thiab engineering. Nws tsis tau tsuas yog txhawb nqa kev nce qib ntawm kev lag luam niaj hnub tab sis kuj qhib txoj kev tshiab rau tib neeg los tshawb txog cov ntaub ntawv sib txawv, thiab ntau dua txhim khu kev qha cov ntaub ntawv. Nrog kev tshawb fawb txuas ntxiv, Titanium hlau raug khi kom ci rau hauv cov teb ntau thiab sau ib tshooj tshiab hauv cov ntawv thov khoom.
