Nyob rau hauv aerospace teb, kev xaiv ntawm cov ntaub ntawv ncaj qha txiav txim siab lub sab sauv txwv ntawm lub aircraft kev ua tau zoo, kev nyab xeeb davhlau thiab cov nqi khiav hauj lwm. Muaj cov khoom uas sawv tawm hauv cov xwm txheej tseem ceeb xws li cov qauv fuselage, cov khoom siv cav, thiab cov khoom siv satellite nrog tag nrho - puag ncig kev ua tau zoo thiab tau dhau los ua "kev xaiv zoo tshaj" nyiam los ntawm kev lag luam - nws yog Ti-15V-3Cr-3Sn-3A titanium alloy.
Rau lub dav hlau, "qhov hnyav txo thiab nce kev ua tau zoo" yog kev nrhiav mus ib txhis, thiab Ti-15V-3Cr-3Sn-3A titanium alloy zoo kawg nkaus txhais cov ntsiab lus zoo ntawm "lub teeb thiab muaj zog". Nws qhov ceev tsuas yog 4.48g / cm³, uas yog sib npaug rau 60% ntawm cov hlau, tab sis tom qab kev laus kev kho mob, lub zog tensile tuaj yeem ncav cuag 1200-1400MPa, thiab lub zog tshwj xeeb tshaj li ntawm aluminium alloys thiab cov tsoos steels.
Raws li cov titanium alloy metastable, TB5 muaj kev ua haujlwm txias txias ua haujlwm hauv lub xeev kev daws teeb meem - qhov txias dov deformation tuaj yeem ncav cuag ntau dua 90%, thiab nws tuaj yeem yooj yim tsim cov ntawv hlau yooj yim xws li cov kab hluav taws xob tiv thaiv lub kaus, thiab tseem tuaj yeem siv rau hauv kev tsim cov fasteners xws li txias taub hau rivets thiab bolts.
Piv nrog rau cov tsoos - hom titanium alloys, Ti-15V-3Cr-3Sn-3A tuaj yeem ua tiav kev ua haujlwm siab yam tsis muaj qhov nruab nrab annealing, uas tsis tsuas yog ua kom yooj yim rau cov txheej txheem tsim khoom, txhim kho kev tsim khoom, tab sis kuj ua kom zoo thiab ua haujlwm ruaj khov ntawm qhov chaw, zoo kawg nkaus ua tiav qhov kev txiav txim siab ntawm qhov chaw siab.
