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. chaw technology. 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 zoo hauv txhua qhov chaw ntawm qhov khoob, paub txog kev ua haujlwm isotropic thiab muab cov khoom siv txhim khu kev qha rau cov foob pob hluav taws 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 nyiam rau cov khoom tseem ceeb los ntawm kev tsim txiaj ntawm lawv. zoo heev tshav kub-kho kho 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{10}}MPa-1100MPa. BT14 alloy, ntawm qhov tod tes, qhia nws qhov tshwj xeeb zoo hauv lub sijhawm muaj zog ntawm σb=1100MPa-1150MPa, uas tsis tuaj yeem tsuas yog siv rau kev tsim cov tubular beam zoo li cov Cheebtsam nrog txoj kab uas hla. los ntawm 80mm mus rau 120mm, tab sis kuj tseem siv tau los ua ib tug fastener nyob rau hauv ib tug tsawg-kub ib puag ncig ntawm -196 degree .
Kev cia siab yav tom ntej ntawm Ti-Al intermetallic compound-based alloys
Txhawm rau txhawm rau txhim kho kev ua tau zoo ntawm qhov chaw foob pob hluav taws, cov kws tshawb fawb tau tig lawv cov xim rau Ti-Al intermetallic compound-based alloys. Cov alloys no suav tias yog qhov zoo tshaj plaws ntawm cov tiam tshiab ntawm qhov chaw foob pob hluav taws vim lawv cov khoom sib xyaw ua ke, siab thermal zog, siab modulus ntawm elasticity thiab tsawg ntom. Tam sim no, "Composites" kev tshawb fawb thiab kev tsim khoom ua ke tau ua haujlwm ntawm kev tsim cov khoom siv txheej txheem rau kev npaj cov ntaub ntawv tshiab no, suav nrog cov khoom siv melting, pelletizing thiab isothermal deformation, txhawm rau txhawb kev siv Ti-Al alloys dav. hauv aerospace sector.
Daim ntawv thov ntawm titanium alloys nyob rau hauv niaj hnub aerospace foob pob ua ntxaij tshuab tsis tau tsuas yog qhia txog qhov tseeb achievements nyob rau hauv cov ntaub ntawv kev tshawb fawb, tab sis kuj foretells lub yav tom ntej kev loj hlob kev taw qhia ntawm aerospace technology. Los ntawm kev tshawb nrhiav tsis tu ncua thiab ua kom zoo rau cov txheej txheem npaj thiab cov khoom ntawm titanium alloys, cov kws tshawb fawb tau muab cov khoom siv txhim khu kev qha thiab muaj txiaj ntsig zoo rau cov foob pob hluav taws hauv qhov chaw, pab tib neeg los tshawb txog cov phiaj xwm loj ntawm lub ntiaj teb.
