Qhov kev ua tiav zoo ntawm Aerospace kev lag luam yog inseparable los ntawm kev txhim kho thiab tawg hauv lub tshuab khoom siv tshuab hluav taws xob. Lub siab siab, kev kub siab thiab siab maneuverability ntawm cov dav hlau factiver kom cov cuab yeej siv tau kom muaj zog txaus raws li lub zog txhav. Cov khoom siv cov khoom siv tau xav tau kom tau raws li qhov kev thov kub ua rau muaj kev kub siab, heigh alloys, tejyam raws li cov khoom siv yog cov khoom tseem ceeb.

Cov hlau sib xyaw ua ke rau saum 300 ℃, ua rau nws tsis phim rau ib puag ncig kub. Hauv kev mus nrhiav ntawm lub zog siab dua hloov pauv kev ua tau zoo, siab dua thiab siab dua cov kev khiav hauj lwm kub yuav tsum muaj nyob rau hauv kev tshav dav hlau lub zog. Kev kub nyhiab alloys tau tsim rau kev ua haujlwm ruaj khov ntawm qhov kub siab tshaj 600 ℃, thiab technology txuas ntxiv mus.

Kev kub nyhiab alloys yog cov ntaub ntawv tseem ceeb rau kev sib faib ntawm cov hlau-uas tau muab faib ua kev kub siab, npib tsib xee los ntawm cov ntsiab lus tseem ceeb ntawm cov alloy. Kev kub nyhiab alloys tau siv nyob rau hauv Aero-engines txij thaum lawv pib, thiab yog cov ntaub ntawv tseem ceeb hauv kev tsim cov tshuab hluav taws xob. Cov qib kev ua tau zoo ntawm lub cav nyob ntawm kev ua haujlwm theem ntawm cov ntaub ntawv kub siab tag nrho. Hauv cov tshuab hluav taws xob niaj hnub-tshuab, tus nqi ntawm cov khoom siv kub siab ntxiv rau cov khoom siv ntawm lub cav, thiab ntxiv rau, cov ntaub ntawv, them nyiaj, them cov pob tw.

Npib tsib xee-raws li kev kub-kub alloys Feem ntau ua haujlwm ntawm 600 ℃ saum toj cov xwm txheej ntawm qee qhov kev ntxhov siab, nws tsis yog muaj lub zog siab, thiab thev taus siab dua, nrog rau kev qaug zog zoo. Mas siv nyob rau hauv lub teb ntawm aerospace thiab aviation nyob rau hauv cov kev mob siab, xws li cov cav ntoo uas muaj lub dav hlau, cov pa taws, sib txuas ua ke thiab lwm yam. Cov npib tsib xee-raws li cov kev kub kub muaj zog tuaj yeem faib ua deformed high allous alloys thiab kev kub siab tshiab alloys raws li kev tsim khoom.

Nrog rau cov cua sov-resistant alloy ua haujlwm kub siab dua thiab siab dua, ntau dua, ntau dua, ntau dua, cov alloys muaj peev xwm tsuas yog siv nyob rau hauv lub xeev pov, tsis tuaj yeem deformed kub ua. Ntxiv mus, qhov nce ntawm alloy cov ntsiab ua rau tsib xee-raws li cov segloid ci nrog cov koom haum tsis sib xws thiab cov khoom tsis sib xws thiab cov khoom.Kev siv ntawm hmoov metallurgy process los tsim cov cua sov siab, tuaj yeem daws cov teeb meem saum toj no.Vim tias cov hmoov av me me, cov hmoov ua kom sov, ua lub zog kub ua rau muaj zog, ua lub zog kub ua rau muaj zog ntau ntxiv tau ua txoj hauv kev tshiab.
