Titanium alloy feem ntau yog siv los ua lub dav hlau cav compressor qhov chaw, ua raws li cov foob pob hluav taws, cuaj luaj, thiab cov khoom siv dav hlau ceev ceev. Los ntawm nruab nrab -1960s, titanium thiab nws cov alloys tau siv rau hauv kev lag luam dav dav los ua cov khoom siv hluav taws xob rau kev lag luam electrolysis, condensers rau cov chaw nres tsheb fais fab, cov cua sov rau cov roj refining thiab seawater desalination, thiab cov khoom siv tswj cov pa phem. Titanium thiab nws cov alloys tau dhau los ua ib yam khoom 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 kawm titanium thiab titanium alloys nyob rau hauv 1956. Nyob rau hauv nruab nrab ntawm lub xyoo 1960, titanium cov khoom yog industrialized thiab tsim rau hauv TB2 alloy.
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 lub zog yog siab dua aluminium thiab steel, thiab nws muaj cov seawater corrosion kuj zoo heev thiab ultra-low kub ua haujlwm. Xyoo 1950, Tebchaws Meskas thawj zaug hauv F-84 fighter-bomber fuselage heat shield, air hood, tail cover, and other non-load bearing components. Txij li thaum xyoo 1960, titanium alloy tau siv los txav ntawm lub fuselage nram qab mus rau nruab nrab lub fuselage, ib nrab hloov cov qauv hlau los ua cov khoom tseem ceeb xws li cov ncej, kab teeb, flaps, thiab slides. Kev siv cov titanium alloy hauv cov tub rog dav hlau tau nce sai, nce mus txog 20 mus rau 25 feem pua ntawm qhov hnyav ntawm cov qauv dav hlau. Txij li thaum xyoo 1970, cov dav hlau dav hlau pib siv ntau cov titanium alloy, xws li Boeing 747 aircraft nrog ntau tshaj 3,640 kilograms ntawm titanium. Rau cov dav hlau nrog Mach cov lej ntau dua 2.5, titanium yog siv tsuas yog siv cov hlau los txo qhov hnyav ntawm cov qauv. Piv txwv li, nyob rau hauv American SR-71 high-altitude high-speed reconnaissance dav hlau (Mach tooj 3, 26,212 meters), titanium suav txog 93 feem pua ntawm qhov hnyav ntawm cov qauv dav hlau, hu ua "tag nrho cov titanium" aircraft. Thaum lub thrust-qhov hnyav piv ntawm aero-cav nce los ntawm 4 ~ 6 mus rau 8 ~ 10 thiab compressor qhov hluav taws xob kub nce ntxiv los ntawm 200 ~ 300 degree mus rau 500 ~ 600 degree, lub compressor tsis tshua muaj compressor discs thiab cov hniav Ameslikas ua los ntawm txhuas. yuav tsum tau ua los ntawm titanium alloy, los yog titanium alloy yuav tsum tau siv es tsis txhob stainless hlau los ua high-pressure compressor discs thiab hniav, thiaj li yuav txo tau qhov hnyav ntawm cov qauv. Nyob rau xyoo 1970, tus nqi ntawm titanium alloy nyob rau hauv aero-engine feem ntau suav txog 20 feem pua rau 30 feem pua ntawm tag nrho qhov hnyav ntawm cov qauv, feem ntau yog siv rau kev tsim cov khoom siv compressor, xws li forged titanium kiv cua, compressor discs thiab hniav, cam khwb cia titanium compressor casing, intermediary casing, bearing vaj tse, thiab lwm yam. Spacecraft mas siv titanium alloy nrog siab tshwj xeeb zog, corrosion kuj, thiab kub-kub kev ua tau zoo los tsim ib tug ntau yam ntawm siab hlab ntsha, roj tso tsheb hlau luam, fasteners, ntsuas straps, thav ntawv, thiab foob pob hluav taws vaj tse. Tib neeg tsim ntiaj teb satellites, lunar modules, manned spacecraft, thiab chaw shuttle kuj siv titanium phaj vuam daim.
