Cov ntaub ntawv ntsuas qhia tau tias thaum lub sijhawm kub nce mus rau 500 degree, nws linear nthuav kev coefficiention tsuas yog 6.0x10 ^ {/ c. Cov yeeb yam no ua rau TA2 txhawm rau kom muaj kev ruaj khov zoo nyob rau hauv cov kev ua haujlwm kub ua haujlwm, ua kom haum rau kev siv ua cov khoom lag luam tsim rau cov khoom lag luam.
3. Anisotropy ntawm Thermal Expansion
Lub thermal expansion thaj chaw ntawm Ta2 titanium alloy muaj qee qhov anisotropy. Nws nthuav kev coefficient yuav yog me ntsis txawv nyob rau hauv cov kev qhia sib txawv. Piv txwv li, qhov sib txawv hauv kev nthuav dav coefficient ntawm kev ntsuas ntev thiab transverse qhia yog hais txog {}. 5x10 ^ {{}}}}} / degree. Qhov sib txawv no yuav tsum tau txiav txim siab tag nrho hauv kev tsim qauv tiag tiag kom tsis txhob muaj kev cuam tshuam ntawm cov khoom siv los ntawm kev ntxhov siab thermal.
2. Kev txheeb xyuas qhov tseeb ntawm TA2 titanium alloy
1. Qiv kev ua tau zoo ntawm chav tsev kub
Qhov ceev ntawm TA2 titanium alloy nyob rau chav tsev kub yog 4.43 uas yog ntau tshaj li ntawm cov ntaub ntawv hlau (xws li cov khoom siv hlau (xws li qhov ntom ntawm txog 7.85 g / cm :). Yog li ntawd, TA2 tau siv dav nyob rau hauv Aerospace teb vim tias nws tuaj yeem txo qis qhov hnyav tag nrho ntawm cov khoom siv thaum tswj lub zog siab.
2. Cov nyhuv ntawm qhov kub ntawm ntom
Raws li kub nce ntxiv, qhov ntom ntawm TA2 txo me ntsis. Piv txwv li, thaum 200c, nws qhov ntom ntom ntom rau 4.40 g / cm3; Ntawm 500c, lub ntom ntom yog li 4.38 g / cm3. Tus cuam tshuam ntawm qhov kub ntawm nws qhov ntom ntom yog me me thiab tsuas yog hloov nyob rau hauv cov ntawv thov pib, yog li hauv feem ntau cov kev hloov pauv ntawm TA2 yog qhov tsis txaus ntseeg.
3.Balance ntawm ntom thiab lub zog
Txawm hais tias qhov ceev ntawm TA2 titanium alloy yog tsawg, nws lub zog tensile
yog siab npaum li 860 mpa mpa mp, nws cov txiaj ntsig lub zog yog 550MPA
Nws yog lub siab-muaj zog thiab cov khoom siv tsawg. Cov xeeb ceem no ua rau nws xaiv qhov zoo tshaj plaws rau kev lag luam tub rog thiab kev lag luam siab tsim kev lag luam.
3. Kev ua kom zoo thiab siv tau ntawm TA2 titanium alloy
1. Kev ua kom zoo ntawm qhov kub thiab txias ruaj khov
Los ntawm kev ua kom zoo dua microstructure ntawm Ta2 titanium alloy, nws ruaj khov hauv kev kub siab ib puag ncig tuaj yeem txhim kho ntxiv. Piv txwv li, los ntawm kev twv ntxiv hauv ntiaj teb lossis siv cov txheej txheem kho cua sov tshwj xeeb thiab oxidation tsis kam ntawm qhov kub tau yooj yim.
