Qhov sib txawv no yuav tsum tau txiav txim siab tag nrho hauv kev tsim qauv tiag tiag kom tsis txhob muaj kev tawm tsam vim yog kev ntxhov siab thermal.
Kev txheeb xyuas qhov tseeb ntawm TA2 (Gr2) 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 g / qis dua li ntawm cov ntaub ntawv hlau xws li 42cmo steel, uas muaj qhov ntom ntawm txog 7.85 g / cm³. Raws li qhov tshwm sim, TA2 tau siv dav hauv lub peev xwm Aerospace vim nws lub peev xwm los txo qhov hnyav tag nrho ntawm lub cuab yeej thaum tswj hwm kev ua lub zog siab.
2. Cov nyhuv ntawm qhov kub ntawm ntom
Raws li qhov kub nce ntxiv, qhov ntom ntawm TA2 txo me ntsis. Piv txwv li, thaum 200 degree, nws cov tee ceev rau 4.40 g / cm³; Ntawm 500 degree, lub ntom yog li 4.38 g / cm³. Tus cuam tshuam ntawm qhov kub ntawm nws qhov ntom ntom me me, hloov tsuas yog nyob rau hauv thawj zaug sim caij nyoog, yog li qhov kev hloov pauv ntom ntawm TA2 yog negrigible hauv cov ntawv thov feem ntau.
3. Sib npaug nruab nrab ntawm ntom thiab lub zog
Txawm hais tias qhov ceev ntawm TA2 titanium alloy yog tsawg, nws lub tensile muaj zog yog li {}} mpa}} mpa, uas yog cov khoom siv muaj zog thiab cov khoom siv tsawg. Cov cuab yeej no ua rau nws zoo rau cov tub rog thiab kev tsim khoom siab.
Kev ua kom tau zoo thiab kev ua tiav ntawm TA2 (Gr2) 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, cov creep tsis kam thiab oxidation tsis kam ntawm qhov siab uas tau txhim kho los ntawm kev ntxiv cov txheej txheem tsis tshua muaj txheej txheem kev kho mob kub tshwj xeeb. Qhov kev txhim kho no ua rau TA2 ntau dav siv nyob rau hauv cov kev kub-kub xws li aerospace tshuab thiab roj av.
2. Cov ntaub ntawv thov cov tswv yim
