Kev faib tawm ntawm Titanium Alloys thiab cov khoom siv tau hauv Aerospace Field
Raws li ib qho tshwj xeeb hlau alloy, titanium alloy plays lub luag haujlwm tseem ceeb hauv aerospace teb nrog nws cov khoom zoo heev ntawm lub cev thiab tshuaj lom neeg. Ntau hom titanium alloys muaj cov yam ntxwv sib txawv, muab kev xaiv ntau dua rau kev xaiv cov khoom siv hauv aerospace teb. Raws li lawv cov microstructure thiab muaj pes tsawg leeg, titanium alloys tuaj yeem faib ua tsib pawg, xws li , , - , metastable alloys thiab high-temperature titanium alloys. Txhua hom titanium alloy yog haum rau cov khoom sib txawv ntawm aerospace.
1.-hom titanium alloy:
Alpha-type titanium alloy yog hom yooj yim tshaj plaws ntawm titanium alloy, thiab nws cov khoom tseem ceeb yog alpha-theem titanium. -phase titanium muaj cov yas zoo thiab cov khoom ua haujlwm, muaj cov qauv ruaj khov ntawm chav tsev kub, thiab feem ntau siv rau hauv qhov chaw corrosion-resistant. Hom titanium alloy no feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj plasticity siab, xws li aerospace, khoom siv kho mob, thiab lwm yam, xws li Compressor blades, turbine disks thiab fasteners hauv dav hlau tshuab.
2.-hom titanium alloy:
Lub ntsiab tivthaiv ntawm -type titanium alloy yog -phase titanium. Beta theem titanium muaj qhov zoo elastic modulus thiab lub zog, nrog rau kev ua haujlwm kub zoo. Beta titanium alloys feem ntau yog siv rau hauv daim ntawv thov nyob rau hauv qhov kub thiab txias ib puag ncig, thiab feem ntau yog siv nyob rau hauv qhov chaw uas yuav tsum tau siab hardness, xws li aerospace cav qhov chaw, tshuaj lom neeg kev lag luam khoom, kiv cua hniav, ducts thiab casings nyob rau hauv dav hlau cav, thiab lwm yam.
3. + titanium alloy:
+ titanium alloy muaj ob theem thiab theem titanium. Hom titanium alloy no ua ke qhov zoo ntawm -phase thiab -phase titanium. Qhov zoo ntawm cov khoom ntawm no dual-theem alloy yog tsim rau cov khoom uas xav tau qhov sib npaug ntawm lub zog, ductility thiab corrosion kuj. Qhov no ua rau nws siv ntau dua hauv thaj chaw aerospace, xws li cov qauv hauv dav hlau, cov khoom siv oxygen, thiab lwm yam.
4. Metastable beta alloy:
Raws li theem, los ntawm kev kho cua sov los yog deformation, cov theem yuav hloov mus rau lwm theem, xws li los yog Ω, yog li txhim kho lub zog thiab toughness ntawm alloy. Metastable beta alloys yog siv nyob rau hauv qhov chaw uas yuav tsum tau muaj zog thiab toughness, xws li rotor hniav, tail seem thiab tis tawv.
5. Kub kub titanium alloy:
High-temperature titanium alloy yog ib hom tshwj xeeb ntawm titanium alloy. Nws cov ntsiab lus yog siab heev nyob rau hauv-theem titanium, thiab nws muaj tsis tshua muaj kub-kub lub zog thiab kub tsis kam. Hom titanium alloy no feem ntau yog siv nyob rau hauv aerospace cav qhov chaw thiab cov roj turbine kub kub. thiab lwm daim ntawv thov kev kub ntxhov. Txawm hais tias nws yog qhov kub-kub qhov chaw ntawm lub cav lossis lub taub hau ntawm lub foob pob hluav taws, qhov kub-kub titanium alloys tuaj yeem ua kom ruaj khov ntawm cov khoom siv nyob rau hauv qhov chaw kub kub nrog lawv cov kub-kub zoo heev.
Cov txheej txheem kev faib tawm ntawm titanium alloys thiab lawv cov ntaub ntawv siv tau hauv thaj chaw aerospace qhia txog kev siv dav dav ntawm titanium alloys hauv thaj chaw aerospace. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, titanium alloys yuav ua lub luag haujlwm tseem ceeb hauv thaj chaw aerospace yav tom ntej thiab txhawb kev txhim kho ntxiv ntawm aerospace technology.
