Hauv kev lag luam aerospace sai sai ntawm lub xyoo pua 21st, qhov kev thov rau aerospace foob pob hluav taws thev naus laus zis tau dhau los ua nruj zuj zus, tshwj xeeb tshaj yog nyob rau hauv kev txhim kho cov tshuab hluav taws xob siab tshwj xeeb, uas yog qhov tseem ceeb rau kev tsav tsheb nce qib hauv qhov chaw thev naus laus zis. Titanium alloys, paub txog lawv qhov tshwj xeeb kub-kub lub zog, tsis tshua muaj kub toughness, thiab muaj peev xwm ua tau zoo, tau tshwm sim los ua cov ntaub ntawv tseem ceeb hauv cov khoom siv thev naus laus zis thev naus laus zis.
Hais txog cov khoom siv hauv aerospace foob pob hluav taws uas tiv taus qhov kub thiab txias xws li -200 degree thiab dhau mus, cov chaw xws li Lavxias Lub Tsev Haujlwm ntawm Hlau tau ua kom zoo dua cov txheej txheem thiab txhim kho kev ua haujlwm ntawm cov hlau xws li BT6c. Cov alloy no tsis tsuas yog ua haujlwm ruaj khov ntawm -200 degree tab sis kuj, los ntawm cov txheej txheem metallurgy particle, tau txo nws cov kev khiav hauj lwm kub txwv mus rau 253 degree, ua kom muaj txiaj ntsig zoo ntawm tag nrho cov khoom siv. Cov txheej txheem tshiab no ua kom cov txheej txheem nplua-grained thoob plaws cov khoom, ua tiav cov khoom isotropic thiab muab cov khoom siv txhim khu kev qha rau cov foob pob hluav taws hauv cov xwm txheej hnyav.
Hauv kev siv dav hauv aerospace foob pob hluav taws, dual-theem titanium alloys xws li BT6c, BT14, BT3-1, BT23, BT16, BT9 (BT8), leveraging lawv zoo heev tshav kub kho zog ntxiv zog, tau dhau los ua cov khoom nyiam rau cov khoom tseem ceeb. Piv txwv li, BT6c alloy, kub-kho rau σb=1050MPa-1100MPa, pom dav daim ntawv thov nyob rau hauv ntau yam high-lub zog yuav tsum tau Cheebtsam. Meanwhile, BT14 alloy, exhibiting tshwj xeeb zoo nyob rau hauv lub high-strength ntau yam ntawm σb=1100MPa rau 1150MPa, yog siv rau manufacturing tubular beam zoo li Cheebtsam nrog diameters li ntawm 80mm mus rau 120mm thiab kuj ua hauj lwm pab raws li fasteners nyob rau hauv qis kub. ib puag ncig mus rau -196 degree .
Txhawm rau txhim kho kev ua tau zoo ntawm foob pob hluav taws, cov kws tshawb fawb tau tig lawv txoj kev tsom mus rau Ti-Al intermetallic compound-based alloys. Cov alloys, paub txog lawv cov khoom tshwj xeeb, siab thermal zog, siab elastic modulus, thiab tsawg ntom, yog pom raws li frontrunners nyob rau hauv lub tiam tshiab ntawm aerospace foob pob hluav taws cov ntaub ntawv. Tam sim no, "Composite Materials" Research thiab Production Joint Company tau mob siab rau tsim cov khoom siv npaj txhij rau cov ntaub ntawv tshiab no, suav nrog cov melting siab heev, spheroidizing, thiab isothermal deformation li, los tsav cov ntawv thov dav dav ntawm Ti-Al alloys hauv aerospace sector.
