TA7 Titanium yog dab tsi?

TA7 Titanium Alloy cov qauv feem ntau ua raws li Suav Tebchaws Cov Qauv (GB / T) thiab cov qauv tsim los ntawm lwm lub tebchaws lossis cheeb tsam. Nov yog qee cov ntaub ntawv ntsig txog tus qauv rau TA7 Titanium Alloy:

GB / T 6612-1986: Ib qho qub Suav Tebchaws Tus Qauv rau TA7 titanium alloy daim hlau. Lus Cim: Cov qauv no yogabolished rau lub kaum hli ntuj 14, 2004.

GB / T 3620.1-2016: Qhov no yog tam sim no Suav Teb Chaws Tus Qauv.

TA7 titanium alloy yog nruab nrab -lub zog - hom titanium alloy, feem ntau siv nyob rau hauv lub xeev annealed. Vim nws cov pob txha zoo toughness thiab fusion weldability, nws pom dav daim ntawv thov nyob rau hauv aerospace teb. Nov yog qee qhov tseem ceeb ntawm kev siv tshuab thiab lub cev ntawm TA7 titanium alloy:

Thov rau Cov Qauv Dawb

Tensile zog (σb):Feem ntau ib ncig690 MPa ua.

Yield zog (σ0.2):Kwv yees li10 MPa.

Elongation (δ):Qhov elongation ntawm chav tsev kub feem ntau tsis qhia meej meej. Txawm li cas los xij, hauv qab-253 degreecryogenic tej yam kev mob, nws elongation tuaj yeem ncav cuag9%.

Kev txo qis ntawm cheeb tsam (Z):Qhov txo qis ntawm cheeb tsam feem ntau kuj siab nyob rau hauv chav tsev kub tab sis tej zaum yuav txo qis hauv - qhov kub thiab txias.

Qhov ceev (ρ):Kwv yees li4.5 g / cm³.

Melting Point:Siab heev, feem ntau nyob ib ncig ntawm1660 degree.

Thermal conductivity:Tus nqi qis, kwv yees li21.7 W/(m·K).

Coefficient ntawm Linear Expansion:Tus nqi qis, kwv yees li8.6 × 10⁻⁶ / degree.

Elastic Modulus:Kwv tij siab, kwv yees110-120 GPa.

Kev kho cua sov:Ua ntej-kev ua cov txheej txheem annealing tej zaum yuav tsum tau los txo cov hardness, txhim kho plasticity, thiab txo cov springback thaum lub sij hawm machining. Kev kho cua sov kub cuam tshuam rau microstructure thiab mechanical zog ntawm TA7 phaj. Piv txwv li, kev kho cua sov nruab nrab ntawm750℃rau 850 degreetuaj yeem txhim kho ob chav -kub thiab siab -kub txhua yam khoom.

Machining:Xaiv qhov tsim nyog txiav ceev, pub tus nqi, thiab qhov tob ntawm kev txiav kom txo qis kev tsim hluav taws xob thiab ua haujlwm thermal deformation. Siv cov kev txiav qis qis thiab cov nqi pub ntau dua. Cov khoom siv tsim nyog suav nrog carbide, ceramics, lossis cubic boron nitride (c-BN).

Forging thiab Rolling:Yas deformation ntawm forging thiab dov yog ua tau tab sis yuav tsum tau nruj tswj ntawm kub thiab deformation tus nqi kom tsis txhob grain loj hlob thiab tawg. Cov txuj ci zoo li pob- dov tuaj yeem tsim TA7 daim hlau nrog cov nplua, zoo li microstructure, zoo dua qhov sib sib zog nqus- kos duab, thiab cov khoom tiav ntau dua.

Vuam:Nws muaj qhov zoo weldability, haum rau tungsten inert gas (TIG) thiab hlau inert gas (MIG) cov txheej txheem nyob rau hauv inert roj tiv thaiv. Kev tu kom zoo thiab kev npaj ua ntej vuam yog qhov tseem ceeb.

Kev kho deg:Cov txheej txheem zoo li anodizing lossis sandblasting tuaj yeem txhim kho corrosion kuj thiab zoo li. Thaum tshav kub kub-kho cov phaj yuav tsum tau kuaj microstructure thiab kuaj ntawm chav-kub/siab-kub txhua yam khoom thiab dabtsi yog khoov kev ua tau zoo.

Kev Tswj Xyuas Zoo:Tsis tu ncua tshuaj xyuas qhov ntev thiab qhov chaw zoo thaum ua haujlwm. Ua cov kev ntsuam xyuas tsim nyog (piv txwv li, hardness, mechanical zog) ntawm cov khoom tiav.

Aerospace:Feem ntau yog siv rau cov khoom xws li aero- cav casings ua haujlwm hauv qab no500 degree. Haum rau cov khoom siv xws li lub nplhaib sib tsoo lub cav, lub plhaub plhaub, thiab cov tawv nqaij ntawm lub dav hlau vim nws cov pob txha zoo toughness thiab weldability.

Cryogenic Engineering:CovTA7 ELI(Ntxiv Tsawg Interstitials) variant tswj zoo toughness, tsis tshua muaj thermal conductivity, thiab tsis tshua muaj siab rhiab heev txawm nyob rau hauv cryogenic kub li tsawg li20K (-253 degree). Nws tau ua tiav zoo siv hauv cov thawv cryogenic, cov kav dej, thiab cov khoom xws li cov kua foob pob hluav taws lub cav impellers.

Spacecraft Structures:Zoo sib xws qis- kub titanium alloys zoo li TA7 ELI muaj peev xwm siv tau hauv cov qauv siv dav hlau.

Cov Khoom Siv Tshuaj:Nws corrosion thiab siab -kub tsis kam muab nws lub peev xwm rau qee yam kev siv tshuaj lom neeg.

Kev Tshawb Fawb Txog Kev Tshawb Fawb:Siv rau hauv kev sim cov cuab yeej thiab cov cuab yeej uas yuav tsum tau muaj ob qho tib si siab - kub thiab qis - qhov kub thiab txias.

Lwm yam kev siv Industrial:Nws tuaj yeem siv los tsim lwm cov khoom lag luam uas xav tau lub zog siab thiab zoo corrosion kuj, xws li cov khoom siv tsheb thiab cov khoom ua si.
