Titanium yeeb nkab yog ib hom tshiab ntawm cov khoom siv hlau, uas tau hloov tag nrho cov kav hlau thiab cov kav hlau steel hauv qee yam. Yog li, nws yog dab tsi uas tso cai rau nws kis tau sai thiab hloov cov hlab ntsha?
1. Lub zog tshwj xeeb ntawm titanium raj yog siab. Qhov ceev ntawm titanium alloy feem ntau yog hais txog 4.5g / cm3, uas tsuas yog 60% ntawm cov hlau, thiab lub zog ntawm cov titanium ntshiab yog ze rau lub zog ntawm cov hlau zoo tib yam, thiab qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov hlau alloy. hlau. Yog li ntawd, lub zog tshwj xeeb (lub zog / ntom) ntawm titanium alloy yog ntau dua li ntawm lwm cov khoom siv hlau, thiab cov khoom uas muaj lub zog siab, zoo rigidity thiab lub teeb yuag tuaj yeem tsim tau. Tam sim no, titanium alloys yog siv nyob rau hauv lub cav Cheebtsam, skeletons, tawv, fasteners thiab tsaws iav ntawm aircraft.
2. Lub thermal zog ntawm titanium raj yog siab. Kev ua haujlwm kub yog ntau pua degrees siab dua li ntawm aluminium alloy, thiab nws tseem tuaj yeem tswj tau lub zog xav tau ntawm qhov kub nruab nrab, thiab tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 450 ~ 500 degree. Ob hom titanium alloys tseem muaj lub zog tshwj xeeb hauv thaj tsam ntawm 150 degree ~ 500 degree, thaum lub zog tshwj xeeb ntawm aluminium alloys txo qis ntawm 150 degree. Kev ua haujlwm kub ntawm titanium alloys tuaj yeem ncav cuag 500 degree, thaum aluminium alloys tuaj yeem ncav cuag qis dua 200 degree.
3. Lub corrosion kuj ntawm titanium raj yog zoo. Titanium alloy ua haujlwm nyob rau hauv huab cua huab cua thiab dej hiav txwv nruab nrab, thiab nws cov corrosion kuj zoo dua li ntawm cov hlau tsis muaj steel, thiab nws tsis kam rau pitting, acid etching, thiab kev ntxhov siab corrosion yog tshwj xeeb tshaj yog muaj zog, thiab nws muaj corrosion kuj zoo heev rau alkali, chloride, chlorine organic teeb meem, nitric acid, sulfuric acid, thiab lwm yam.
4. Kev ua haujlwm kub qis ntawm titanium raj yog qhov zoo. Titanium alloys tseem tuaj yeem tswj hwm lawv cov khoom siv dag zog ntawm qhov qis thiab ultra-tsawg kub. Titanium alloys uas muaj qhov kub thiab txias zoo heev thiab cov ntsiab lus tsis sib xws, 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. Cov tshuaj ua haujlwm ntawm titanium raj yog loj. Titanium muaj tshuaj lom neeg zoo heev thiab ua rau muaj zog tshuaj tiv thaiv nrog O, N, H, CO, CO2, dej vapor, ammonia, thiab lwm yam hauv huab cua. Thaum cov ntsiab lus carbon ntau dua 0.2%, TiC nyuaj yuav tsim nyob rau hauv titanium alloy, thiab thaum kub siab, txheej tawv tawv ntawm TiN kuj yuav tsim los ntawm kev sib cuam tshuam nrog N, thiab Thaum cov ntsiab lus carbon siab tshaj 600 degree, titanium yuav nqus oxygen los tsim cov txheej txheem tawv tawv nrog lub siab tawv, thiab txheej brittleness kuj yuav tsim thaum cov ntsiab lus hydrogen nce. Titanium kuj muaj cov tshuaj lom neeg muaj txiaj ntsig zoo, thiab nws yooj yim rau kev ua raws li kev sib txhuam ntawm qhov chaw.
6. Lub thermal conductivity ntawm titanium raj yog me me thiab elastic modulus yog me me. Lub elastic modulus ntawm titanium alloy yog hais txog 1/2 ntawm cov hlau, yog li nws rigidity tsis zoo, yooj yim rau deform, thiab nws tsis tsim nyog los ua slender rods thiab nyias-walled qhov chaw, thiab lub rebound tus nqi ntawm machined nto yog heev loj. Thaum txiav, uas yog kwv yees li 2 ~ 3 npaug ntawm cov hlau tsis muaj steel, ua rau muaj kev sib txhuam hnyav, adhesion, thiab kev sib khi hnav ntawm lub ntsej muag ntawm lub cuab yeej.
Titanium raj yog hlub los ntawm cov neeg los ntawm txhua qhov chaw ntawm lub neej vim nws lub teeb yuag, siv tau yooj yim, kev ua tau zoo, me me ceev thiab lwm yam zoo, thiab yog siv dav. Nws ua lub luag haujlwm tseem ceeb hauv cov tshuab dav hlau, foob pob hluav taws, thiab cuaj luaj.
