Kev cuam tshuam ntawm Forging txheej txheem ntawm lub koom haum thiab cov khoom ntawm Titanium Alloy Bars

Nyob rau hauv xyoo tas los no, nrog kev nthuav dav ntawm kev lag luam, Tuam Tshoj txoj kev lag luam titanium tau tsim muaj txiaj ntsig zoo, thiab cov qib tshiab titanium alloy tau tsim thiab siv. Tam sim no, feem ntau siv titanium alloys hauv tsev thiab txawv teb chaws yog TC4 (Ti-6A-4V), Ti-6Al-2Sn-4Zr -2Mo thiab lwm yam. Txawm li cas los xij, tus nqi siab ntawm titanium alloys thiab qhov nyuaj ntawm smelting thiab kev ua haujlwm ua rau tus nqi siab ntawm titanium, uas yog 8-10 zaus kim dua hlau. Qee zaum, tus nqi txwv tsis pub siv cov titanium alloys.

Lub TC4 (Ti-6A-4V) alloy yog ib tug raug a+0 ob-theem alloy. Cov alloy tau tsim nyob rau hauv Tebchaws Meskas hauv xyoo 1950 thiab muaj cov khoom zoo tag nrho. Nws muaj cov txheej txheem zoo heev plasticity thiab superplasticity. Nws yog tsim rau txhua yam ntawm cov molding siab thiab yog dav siv nyob rau hauv aviation thiab aerospace industries. Nws tuaj yeem siv los tsim ntau qhov chaw nrog kev ua haujlwm kub hauv qab 400 degree, suav txog ntau tshaj li ib nrab ntawm cov tshuaj titanium alloys.Thaum xyoo 1950, Tuam Tshoj pib kawm thiab sim tsim Ti-6Al{{9} }}V alloy.Nyob rau xyoo 1970, nws tau raug hu ua TC4 alloy, uas yog ib qho ntawm cov hlau loj tshaj plaws hauv kev tsim khoom thiab kev siv ntawm ntau cov titanium alloys imported thiab imitated los ntawm Tuam Tshoj. Raws li Mo thiab V nyob rau hauv titanium alloy yog tib yam duab ntsiab tab sis kuj ruaj khov, Tuam Tshoj cov khoom siv molybdenum dua li molybdenum thiab vanadium cov peev txheej muaj ntau, kev siv peev xwm loj heev.

Cov ntaub ntawv sim yog BTi62 titanium alloy ingots melted peb zaug hauv lub tshuab nqus tsev nws tus kheej melting hluav taws xob arc rauv. Lub 0 theem hloov kub ntawm lub ingot yog 1000 ~ 1020 degree . Cov ingots tau forged nyob rau hauv 2500T ceev forging tshuab, 3150T dej xovxwm thiab SXP nplua forging tshuab. Cov khoom tiav ntawm 027.5 hli tau txais.

TC4 (Ti-6Al-4V) alloy feem ntau yog siv rau kev ua haujlwm kub hauv qab 450 degree . BTi62 titanium alloy yog tsim los hloov V keeb nrog Mo lub caij, thiab qhov kev ua tau zoo ntawm cov hlau no piv nrog TC4 (Ti-6A 4V). Tam sim no qhov kub siab tensile Performance index rau TC4 alloys nyob rau hauv lub teb chaws qauv thiab lub teb chaws cov qauv tub rog yog 400 degree. Yog li ntawd, nyob rau hauv txoj kev tshawb no ntawm BTi62, 400 degree high-temperature tensile zog tau muab piv nrog cov tib specification TC4.
