Titanium alloy muaj lub zog siab, tsis tshua muaj siab, zoo txhua yam khoom, toughness thiab corrosion kuj. Tsis tas li ntawd, titanium alloys muaj cov txheej txheem ua haujlwm tsis zoo thiab nyuaj rau kev txiav. Hauv kev ua haujlwm kub, nws yooj yim heev rau nqus cov impurities xws li hydrogen, oxygen, nitrogen, thiab carbon. Kuj tseem muaj kev puas tsuaj tsis zoo thiab cov txheej txheem ntau lawm. Kev tsim khoom ntawm titanium pib hauv xyoo 1948. Txoj kev loj hlob ntawm kev lag luam aviation yuav tsum muaj kev lag luam titanium tsim ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 8%. Lub ntiaj teb' cov khoom tsim tawm txhua xyoo ntawm titanium alloy ua cov ntaub ntawv tau mus txog ntau dua 40,000 tons, nrog ze li 30 qib titanium alloy. Feem ntau siv titanium alloys yog Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) thiab muaj titanium ntshiab (TA1, TA2 thiab TA3).
Titanium alloy feem ntau yog siv rau kev tsim cov aircraft cav compressor Cheebtsam, ua raws li cov qauv ntawm cov foob pob ua ntxaij, missiles thiab high-ceev aircraft. Hauv nruab nrab xyoo 1960, titanium thiab nws cov alloys tau siv dav hauv kev lag luam los ua cov khoom siv hluav taws xob hauv kev lag luam electrolysis, condensers hauv cov chaw nres tsheb fais fab, cov cua sov rau roj av refining thiab seawater desalination, thiab ib puag ncig muaj kuab paug tswj cov cuab yeej. titanium thiab nws cov alloys tau dhau los ua ib yam ntawm cov khoom siv corrosion-resistant. Tsis tas li ntawd, nws kuj yog siv los tsim cov khoom siv hydrogen cia thiab cov duab nco alloys.
Tuam Tshoj pib tshawb fawb txog titanium thiab titanium alloys hauv xyoo 1956; Nyob rau hauv nruab nrab-1960s, industrialized zus tau tej cov ntaub ntawv titanium pib thiab tsim rau TB2 alloys.
Titanium alloy yog cov khoom siv tseem ceeb tshiab siv hauv kev lag luam aerospace. Nws qhov tshwj xeeb lub ntiajteb txawj nqus, lub zog thiab kev pabcuam kub yog nyob nruab nrab ntawm txhuas thiab hlau, tab sis nws muaj zog dua li txhuas thiab hlau thiab muaj cov seawater corrosion kuj zoo heev thiab ultra-low kub ua haujlwm. Xyoo 1950, Tebchaws Meskas tau siv nws thawj zaug ntawm F-84 fighter bomber raws li cov khoom uas tsis yog-loading xws li rear fuselage heat shields, cua deflectors, thiab tail cover. Txij li thaum xyoo 1960, kev siv cov titanium alloy txav los ntawm lub fuselage rear mus rau nruab nrab lub fuselage, ib nrab hloov cov qauv steel los ua ib qho tseem ceeb load-bearing Cheebtsam xws li bulkheads, beams, thiab flap slides. Tus nqi ntawm titanium alloy siv nyob rau hauv tub rog aircraft tau nce sai heev, mus txog 20% mus rau 25% ntawm qhov hnyav ntawm cov qauv dav hlau. Txij li thaum xyoo 1970, pej xeem aircraft pib siv titanium alloys loj. Piv txwv li, Boeing 747 neeg caij dav hlau siv ntau tshaj 3,640 kilograms ntawm titanium. Lub dav hlau nrog tus lej Mach ntau dua 2.5 siv titanium los hloov cov hlau kom txo qhov hnyav ntawm cov qauv. Piv txwv li, US SR-71 high-altitude thiab high-speed reconnaissance aircraft ( ya Mach naj npawb 3, ya qhov siab 26212 meters), titanium account rau 93% ntawm qhov hnyav ntawm lub dav hlau qauv, thiaj li hu ua" ;tag nrho-titanium" dav hlau. Thaum lub thrust-rau-hnyav piv ntawm aero engine nce los ntawm 4-6 mus rau 8-10, thiab compressor qhov hluav taws xob kub nce los ntawm 200-300 ° C mus rau 500-600 ° C, thawj low-pressor compressor discs thiab hniav. ua los ntawm txhuas yuav tsum Siv titanium alloy es tsis txhob, los yog siv titanium alloy es tsis txhob stainless hlau los ua high-pressure compressor discs thiab cov hniav kom txo tau cov qauv hnyav. Nyob rau xyoo 1970, tus nqi ntawm titanium alloy siv nyob rau hauv aero xyaw feem ntau suav txog 20% mus rau 30% ntawm tag nrho qhov hnyav ntawm cov qauv. Nws yog tsuas yog siv los tsim cov khoom siv compressor, xws li forged titanium kiv cua, compressor discs thiab hniav, nrum titanium compressor casings, thiab intermediaries. Cov ntaub ntawv, cov kabmob vaj tsev, thiab lwm yam. Lub dav hlau siv lub zog tshwj xeeb, kev tiv thaiv corrosion thiab tsis kub tsis kam ntawm titanium alloys los tsim ntau yam kev siab ntawm cov hlab ntsha, cov roj tso tsheb hlau luam, cov hlua khi, cov hlua khi, cov qauv thiab cov foob pob hluav taws. Artificial ntiaj teb satellites, lunar modules, manned spacecraft thiab chaw shuttles kuj siv titanium alloy daim ntawv welded qhov chaw.
