BT22 tseem hu ua TC18 hauv Suav teb lossis Ti-5Al-4.75Mo-4.75V-1Cr-1Fe
BT22 high-strength nyob ze -type titanium alloy, nws nominal muaj pes tsawg leeg Ti-5Al-5Mo-5V-1Cr-1Fe, nws cov tshuaj muaj pes tsawg leeg yog : 4.5%{{10}}.9% Al, 4.0%-5.0% Mo, 4.{20 }}%-5.5% V, 0.5%-2.0% Cr, 0.5%-1.5% Fe, cov hlau muaj qib siab ntawm lub zog nyob rau hauv lub xeev annealed, uas muaj peev xwm ncav cuag 1080Mpa, nrog ntxiv dag zog rau kev kho mob, lub zog kuj mus txog 1300Mpa, uas yog annealed nyob rau hauv cov uas twb muaj lawm titanium alloy Cov alloy nrog lub siab tshaj plaws lub zog thiab zoo heev hardenability. Lub thickness ntawm cross-section hardenability tuaj yeem ncav cuag 250mm. Txij li thaum lub thickness ntawm tus ntoo khaub lig-section tsis txwv los ntawm hardenability, zoo tib yam uas tsis muaj nqi tuag forging (ntawm ib tug tuag forging rauj) thiab kub tuag forging yuav siv tau ntau yam txheej txheem, xws li isothermal tuag forging, tsim ze-net zoo forgings. , yog li nws tsim nyog rau kev tsim cov dav hlau loj hauv cov kabmob.
Nws muaj cov yam ntxwv ntawm lub zog siab, siab toughness, zoo plasticity thiab zoo heev vuam kev ua tau zoo. Cov hlau tuaj yeem siv los tsim cov fasteners ntawm lub fuselage, tis quab yuam qhov chaw thiab kev ua haujlwm uas ua haujlwm ntawm 350-400 degree ntev. Nws tseem tuaj yeem siv los tsim cov kiv cua discs thiab cov hniav ntawm cov cav uas nws qhov kub thiab txias tsis siab tshaj 350 degree. Bt22 alloy hloov cov hlau muaj zog hauv cov qauv dav hlau, uas tuaj yeem txo qhov hnyav los ntawm 15%-20%.

Nws muaj qhov zoo ntawm lub zog siab, siab plasticity, zoo hardenability thiab weldability. Cov qauv annealed muaj roughly tib tus lej ntawm ib theem thiab theem. Nws yog lub zog siab tshaj plaws titanium alloy nyob rau hauv lub xeev annealed. TC18 titanium alloy kuj tseem tuaj yeem welded nyob rau hauv ntau txoj kev rau vuam, tom qab annealing, nws muaj vuam zoo, thiab qhov siab tshaj plaws ua hauj lwm kub yog 400 degree.
BT22 titanium alloy yog tsuas yog siv rau loj load-bearing Cheebtsam thiab qhov chaw ntawm aircraft lub cev thiab tsaws iav, thiab kuj siv los tsim cav kiv cua discs thiab hniav uas nws ua hauj lwm kub tsis tshaj 350 degree, thiab kuj siv los tsim cov kabmob tseem ceeb xws li rab rawg. thiab torque caj npab ntawm tsaws iav Force tus tswv cuab. Nws kuj tseem siv rau hauv cov foob pob hluav taws, phom loj, mortars, plhaub, thiab lwm yam.
