Kev tsom xam ntawm thermal expansion zog thiab linear expansion coefficient ntawm TA2 titanium tag nrho
1. Taw qhia rau TA2 titanium alloy
TA2 titanium alloy yog ib hom kev lag luam ntshiab titanium uas tau siv dav hauv aerospace, tshuaj thiab lwm yam lag luam vim nws zoo heev corrosion kuj, lub teeb yuag, siab zog, thiab cov txheej txheem zoo. Nyob rau hauv siab - ib puag ncig kub, thermal expansion zog ntawm cov ntaub ntawv yog ib qho tseem ceeb cuam tshuam rau lawv stability thiab raug, yog li kev nkag siab txog cov thermal expansion zog ntawm TA2 titanium alloy yog qhov zoo heev siv tus nqi rau kev siv.
2. Kev txhais ntawm thermal expansion kev ua tau zoo
Thermal expansion yog hais txog lub peev xwm ntawm cov khoom siv los hloov ntim lossis ntev nrog qhov kub thiab txias thaum nws hloov. Nws feem ntau yog piav raws li cov kab sib txuas sib txuas, uas yog qhov hloov pauv ntawm ib chav tsev ntev ntawm cov khoom nyob rau hauv ib chav tsev kub hloov, feem ntau nyob rau hauv μm / m·℃. Rau siab - qhov kub thiab txias, coefficient ntawm thermal expansion ntawm cov khoom yog ib qho tseem ceeb parameter, ncaj qha cuam tshuam rau cov qauv kev ruaj ntseg ntawm cov khoom nyob rau hauv kub hloov pauv.
Lub linear expansion coefficient ntawm TA2 titanium alloy
3. Kev suav ntawm linear expansion coefficient
Lub linear expansion coefficient ntawm TA2 titanium alloy tuaj yeem ntsuas kev sim thiab feem ntau yog ntsuas hauv qhov kub ntawm 20℃txog 500 degree. Raws li kev sim cov ntaub ntawv, cov linear expansion coefficient ntawm TA2 titanium alloy ntawm qhov sib txawv kub yog raws li nram no:
Ntawm 20 degree, linear expansion coefficient ntawm TA2 titanium alloy yog hais txog 8.6 × 10⁻⁶ / degree.
Ntawm 300 degree, linear expansion coefficient nce mus rau 9.1 × 10⁻⁶ / degree.
Ntawm 500 degree, nws nce mus txog 9.6 × 10⁻⁶ / degree.
Nws tuaj yeem pom tau tias cov kab nthuav dav coefficient ntawm TA2 titanium alloy maj mam nce nrog qhov nce ntawm qhov kub, uas txhais tau hais tias cov khoom yuav tsim thermal expansion ntau dua ntawm qhov kub thiab txias. Yog li ntawd, thaum tsim TA2 titanium alloy cov khoom siv rau hauv siab - qhov kub thiab txias, nws cov yam ntxwv nthuav dav yuav tsum tau txiav txim siab tag nrho.
4. Cov yam ntxwv cuam tshuam rau thermal expansion zog ntawm TA2 titanium alloy
a. Qhov kub thiab txias
Raws li tau hais los saum no, cov kab nthuav dav coefficient ntawm TA2 titanium alloy nce nrog nce kub. Tshaj li 300 degree, thermal expansion tus cwj pwm ntawm cov khoom yog ntau pronounced, qhia tau hais tias qhov kub thiab txias ntau yam yog ib qho tseem ceeb rau lub thermal expansion kev ua tau zoo.
b. Purity thiab microorganization
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm TA2 titanium alloy yog qhov yooj yim, feem ntau yog tsim los ntawm titanium cov ntsiab lus, tab sis muaj cov kab tsis huv hauv cov hlau, xws li oxygen, hydrogen thiab lwm cov ntsiab lus, kuj tseem yuav cuam tshuam rau nws cov thermal expansion zog. Piv txwv li, kev nce hauv cov ntsiab lus ntawm cov pa oxygen tuaj yeem txo qhov kev nthuav dav coefficient ntawm cov hlau thiab cuam tshuam rau nws qhov siab -kub txhua yam khoom.
c. Kev ntxhov siab thiab kev kho cua sov
Cov qoob loo loj thiab cov kev ntxhov siab sab hauv ntawm cov khoom siv yuav sib txawv hauv cov kev kho cua sov sib txawv, uas yuav ua rau muaj kev hloov pauv hauv thermal expansion zog. Annealed TA2 titanium alloys feem ntau muaj ntau yam thermal expansion zog.
5. Cov lus xaus
TA2 titanium alloy muaj ib tug linear expansion coefficient uas nce nrog qhov kub thiab txias, thiab nws cov thermal expansion kev ua tau zoo muaj feem xyuam rau qhov kub thiab txias, alloy muaj pes tsawg leeg thiab cov txheej txheem kho. Nyob rau hauv siab - qhov kub thiab txias, cov neeg tsim qauv yuav tsum ua tib zoo xav txog qhov nthuav dav ntawm TA2 titanium alloy raws li qhov tshwj xeeb kev khiav hauj lwm kub thiab ib puag ncig los xyuas kom meej lub sij hawm ntev - ruaj khov thiab raug ntawm cov khoom.
