Thaum tshav kub kub-resistant titanium alloy, tseem hu ua high-temperature titanium alloy. Titanium alloy nrog lub zog siab ntawm 400 ~ 600 degree. Nws tuaj yeem muab faib ua ntau hom thiab ze rau hom titanium alloys raws li lawv cov microstructure. Martensite ntxiv rau titanium alloy yog BT9, muaj pes tsawg leeg yog Ti-6.5Al-3.5Mo-1.5Zr-0.3Si, thiab qhov kev pabcuam kub yog 500 degree . Feem ntau ntawm cov tswv yim alloys nyob ze, Ti-6242 alloy muaj pes tsawg leeg yog Ti-6Al-2Sn-4Zr-2Mo, siv kub 540 degree ; Cov muaj pes tsawg leeg ntawm IML-834 alloy yog Ti-5.8Al-4Sn-3.5Zr-0.7Nb-0.5Mo{{30} }.35Si, thiab qhov kev pabcuam kub tuaj yeem ncav cuag 600 degree . Nws yog tsuas yog siv nyob rau hauv kev tsim cov aero-engine compressor discs thiab rotor hniav. Lub zog muaj zog heev yog yuav tsum tau tsim cov compressor discs, uas tsim nyog rau ob lub xeev lossis pob tawb zoo li cov qauv. Compressor rotor hniav yuav tsum muaj zog qaug zog ntawm chav tsev kub thiab kub thiab yuav tsum tau equiaxed.
Titanium thiab titanium alloys yog lub teeb yuag, siab zog, corrosion-resistant structural cov ntaub ntawv, nyob rau hauv aviation, aerospace, ships, riam phom, tshuaj, petrochemical, metallurgy, hluav taws xob fais fab, lub teeb kev lag luam, ntsev, kev tsim kho, dej hiav txwv engineering, tshuaj, kev ua si khoom thiab Cov cuab yeej siv hauv lub neej txhua hnub thiab lwm yam haujlwm tau siv dav.
Aero-engine yog ib qho ntawm qhov ntxov tshaj plaws thiab zoo tshaj plaws ntawm titanium alloy daim ntawv thov. Raws li thaum ntxov xyoo 1870, tus nqi ntawm titanium alloy nyob rau hauv Lavxias teb sab aero-engine mus txog 50 feem pua ntawm cov khoom siv hlau. Nyob rau hauv xyoo tas los no, nws yog ib qho tseem ceeb uas kev siv cov titanium alloy nyob rau hauv cov tub rog aircraft cav cov khoom tau qhia ib tug poob zuj zus, ntawm qhov tsis tooj, kev siv cov titanium alloy nyob rau hauv loj pej xeem cav tau qhia ib tug zuj zus qauv.
Qhov kev nce qib no feem ntau yog los ntawm kev siv dav dav ntawm cov roj turbine xyaw hauv cov neeg caij dav hlau loj, kev sib sau ntawm kev paub hauv titanium alloy ntau lawm thiab daim ntawv thov, thiab kev txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm titanium alloy. Tam sim no, turbofan cav siv nyob rau hauv cov neeg nrog caij dav hlau loj thiab thauj cov dav hlau yog qhov zoo tshaj plaws. Daim ntawv thov ntawm titanium alloy nyob rau hauv hom tshiab roj turbine kiv cua cav yog pom tseeb heev los ntawm qhov pom ntawm qhov hnyav txo. Nyob rau hauv xyoo tas los no, cov khoom ntawm lub cav no tau nce ntau thiab tau qhia txog kev nce ntxiv.
Cov hom tshiab ntawm combustion turbofan cav, titanium alloy rau ntau npaum li cas ntawm cov tub rog cav yog qhia ib tug downward trend, lub ntsiab yog vim li cas rau txo tus naj npawb ntawm cov tub rog cav nrog tus txheeb ze npaum li cas ntawm titanium, yuav txhais tau raws li qhov ntau lawm batch. tsawg dua, kuj tseem tuaj yeem txhais tau tias xav siv los ntawm cov tub rog dav hlau cav yog lub cav turbojet supersonic ceev cav, vim li ntawd, tus nqi ntawm titanium kuj tsawg dua.
Titanium yog siv los ua cov disks, hniav, thiab cais tawm rau lub cav kiv cua thiab compressors, nrog rau cov cav ntim rau hauv lub cav, cov khoom cua, thiab lwm yam. Thaum tshav kub kub-resistant titanium alloy feem ntau tuaj yeem ua haujlwm ntawm qhov kub ntawm 500 ~ 550 degree, txawm tias ntawm 600 degree tuaj yeem ua haujlwm ib txwm, thiab cov qauv ntawm titanium alloy tsuas tuaj yeem ua haujlwm ntawm 300 ~ 350 degree.
Cov txheej txheem titanium alloy muaj lub zog tshwj xeeb zoo dua, plasticity, thiab tawg tsis kam tshaj qhov kub-resistant titanium alloy, yog li nws yog qhov tshwj xeeb tshaj yog tsim rau kev tsim cov hniav thiab cov hniav ntawm cov turbofans loj.
Ntau cov ntaub ntawv thiab cov ntaub ntawv qhia tau hais tias kev hloov cov khoom siv hlau nrog titanium alloy rau lub tshuab dav hlau tuaj yeem txo qhov hnyav ntawm lub cav qauv los ntawm 30 feem pua ~ 40 feem pua. Kev lag luam ntawm qhov hnyav txo yog nyob ntawm qhov ntau thiab tsim ntawm cov qauv titanium alloy.
