5. Kev nyuaj
Zaj piav: Qhov tsis kam ntawm txhuas mus rau deformation nto, khawb, lossis indentation.
Cov nqi raug: Aluminium lub hardness yog tsawg dua piv rau cov hlau. Lub hardness rau ntshiab txhuas yog ib puag ncig15 txog 25 brinellCov. Aluminium alloys tuaj yeem muaj tus nqi hardness ntawm60 mus rau 150 Brinell, nyob ntawm cov alloy.
Cov Ntawv Thov: Txhuas Alloys nrog Hardness Ntau dua yog siv hauv Aerospace thiab cov ntawv thov tub rog rau lawv cov kev hnav tsis kam ua tsis kam.
6. Qaug zog muaj zog
Zaj piav: Muaj peev xwm ntawm txhuas kom withstand rov loading thiab unloading mus ncig tsis muaj swb.
Cov nqi raug: Kev qaug zog yog feem ntau qis dua rau txhuas piv rau cov hlau, tab sis tuaj yeem txhim kho hauv cov alloys xws li2024lossis7075.
Cov Ntawv Thov: Lub zog nkees yog ib qho khoom tseem ceeb hauv cov ntawv thov zoo li cov dav hlau wings thiab cov khoom siv hluav taws xob uas raug xa mus rau kev xav tau tsheb.
7. Modulus ntawm elasticity (cov tub ntxhais hluas tus modulus)
Zaj piav: Ib qho kev ntsuas ntawm lub ntsej muag txhav ntawm txhuas, piav txog cov khoom siv tiv thaiv tsis ncaj ncees rau kev ntxhov siab.
Cov nqi raug: Cov modulus ntawm elasticity rau txhuas yog ib ncig69 GPA (gigapascals), uas yog hais txog ib feem peb ntawm tus nqi rau cov hlau.
Cov Ntawv Thov: Cov cuab yeej no yog qhov tseem ceeb rau cov ntawv thov uas txhav thiab deformation hauv qab yog qhov tseem ceeb, xws li hauv cov choj, thiab cov qauv aerospace.
8. Poisson tus piv
Zaj piav: Qhov sib piv ntawm cov kab ke ntawm cov kab ke rau axial lim hauv txhuas thaum xyab.
