Cov ntawv thov tseem ceeb thiab R & D tshiab ntawm Titanium Alloys nyob rau niaj hnub Space Rocket Technology

Nrog rau txoj kev loj hlob sai ntawm qhov chaw lag luam nyob rau hauv lub xyoo pua 21st, qhov yuav tsum tau rau qhov chaw foob pob ua ntxaij tshuab tau dhau los ua nruj me ntsis, tshwj xeeb tshaj yog kev tshawb fawb thiab kev loj hlob ntawm siab impulse thrust-rau-hnyav piv xyaw xyaw, uas tau dhau los ua tus yuam sij rau kev txhawb nqa kev vam meej. tshuab tshuab. Nyob rau hauv cov ntsiab lus no, titanium alloy, raws li ib tug hlau khoom uas zoo heev kub-kub lub zog, low-temperature toughness thiab zoo ua hauj lwm, tau dhau los ua ib tug tseem ceeb cov ntaub ntawv nyob rau hauv advanced chaw foob pob ua ntxaij technology.
Kev tshawb fawb ntawm titanium alloy daim ntaub ntawv nyob rau hauv huab ib puag ncig
Lub koom haum Lavxias teb sab ntawm hlau ua hauj lwm rau cov txheej txheem optimization thiab kev ua tau zoo ntawm BT6c alloy rau cov khoom ntawm qhov chaw foob pob hluav taws uas raug kub heev ({1}} degree mus rau siab dua), xws li loj φ600mm drop-forged qhov chaw, accumulator daim hlau , bearing bracket blanks, thiab tube fittings. Cov alloy tsis tsuas yog ua haujlwm ruaj khov ntawm -200 degree, tab sis nws cov kev txwv kub ua haujlwm tau raug txo qis dua mus rau 253 degree los ntawm particle metallurgy thev naus laus zis, uas txhim kho qhov kev ua tau zoo ntawm cov khoom siv. Cov txheej txheem tshiab no ua kom lub homogeneity ntawm cov qauv siv lead ua zoo nyob hauv txhua qhov chaw ntawm qhov khoob, paub txog cov khoom isotropic thiab muab cov khoom siv txhim khu kev qha rau cov foob pob hluav taws nyob rau hauv cov xwm txheej huab cua.

Kev siv dav thiab kev ua kom zoo ntawm ob-theem titanium alloys
Hauv kev siv dav hauv qhov chaw foob pob hluav taws, ob-theem titanium alloys, xws li BT6c, BTl4, BT3-1, BT23, BTl6, BT9 (BT8), thiab lwm yam, tau dhau los ua cov khoom xaiv rau cov khoom tseem ceeb los ntawm kev tsim txiaj. ntawm lawv cov kev kho cua sov zoo zog ntxiv zog. Piv txwv li, BT6c alloy yog dav siv nyob rau hauv ntau yam ntawm cov khoom uas yuav tsum tau muaj zog siab nyob rau hauv lub tshav kub kev kho mob muaj zog lub xeev ntawm σb=1050MPa-1100MPa. BT14 alloy, ntawm qhov tod tes, qhia nws qhov tshwj xeeb zoo nyob rau lub sijhawm muaj zog ntawm σb=1100MPa-1150MPa, uas tsis tuaj yeem siv rau kev tsim cov kab teeb ci zoo li cov khoom siv nrog cov diameters xws li los ntawm 80mm mus rau 120mm, tab sis kuj tseem siv tau los ua ib qho fastener nyob rau hauv ib puag ncig kub ntawm -196 degree .
