Thermal expansion coefficient ntawm aluminium pas nrig

Lub thermal expansion coefficient ntawm txhuas rods feem ntau yog hais txog 23.6 × 10 ^ -6 / degree ​​ nyob rau hauv qhov kub ntawm 20 degree mus rau 100 degree . Qhov no txhais tau hais tias thaum qhov kub ntawm aluminium pas nrig nce 1 degree, nws qhov ntev yuav nce ntxiv los ntawm 23.6 × 10^-6 zaug. Tsis tas li ntawd, thermal expansion coefficient ntawm 2024 aluminium alloy yog 23.1 × 10 ^ -6 / degree . Qhov kev hloov me me no tuaj yeem ua rau muaj kev cuam tshuam loj rau tag nrho cov kev ua tau zoo nyob rau hauv high-tech teb xws li precision machinery thiab aerospace. cov

Nkag siab txog cov thermal expansion coefficient ntawm aluminium rods yog qhov tseem ceeb rau kev kwv yees thiab tswj kev ua tau zoo ntawm cov khoom siv txhuas hauv qhov chaw thermal. Piv txwv li, yog tias tus pas nrig txhuas muaj qhov kub thiab txias hloov thaum lub sijhawm tsim khoom, nws qhov ntev yuav hloov pauv, cuam tshuam rau qhov tseeb ntawm qhov sib dhos. Yog li ntawd, thaum lub sij hawm tsim thiab tsim cov txheej txheem, engineers yuav tsum tau xav txog tag nrho cov thermal expansion coefficient ntawm txhuas rods los xyuas kom meej cov khoom stability thiab kev ntseeg tau.

Lub thermal expansion coefficient ntawm ib tus pas nrig Aluminium tau hais txog qhov ntev uas qhov ntev lossis ntim ntawm cov khoom siv txhuas nthuav thaum ua kom sov. Nkag siab txog qhov kev ntsuas no yog qhov tseem ceeb kom ntseeg tau tias kev ua tau zoo ntawm cov khoom txhuas nyob rau ntau qhov kev mob siab.
