Q1: Yuav ua li cas cov khoom siv alloying hloov txhuas cov khoom?
Tooj liab (2xxx series) txhim kho lub zog tab sis txo corrosion tsis kam; Magnesium (5xxx) txhim kho weldability thiab marine corrosion tsis kam; silicon (4xxx) lowers latters melting pointing rau kev casting; Zinc (7xxx) ua rau muaj kev kub ntxhov rau kev ua haujlwm. Manganese (3xxx) Lub zog dej haus dej haus cov kaus poom uas tsis muaj kev sib cuam tshuam. Txhua lub ntsiab lus hloov kho cov qauv siv lead ua, kev tshem tawm txav, thiab precipitate tsim.
Q2: Dab tsi ua rau qhov txawv ntawm Wrought vs. Nrov txhuas alloys?
Wrought alloys (1XXX - 8xxx series) yog homogenized thiab rolled rau hauv semi- Cov khoom tiav, xav tau kev ua tiav siab rau kev ua tiav. Nrum alloys (piv txwv li, 356, 380) muaj ntau dua silicon (txog li 12%) rau fluidity hauv pwm. Wought siv Alloys siv cov kev npau taws (H1X, T6), thaum nrum alloys Qhia meej cov lus kho kom sov li F (raws li T6 (daws +.
Q3: Yuav ua li cas T6 Tempering Zog Aluminium?
T6 koom nrog kev kho kom sov ntawm 480-575℃kom yaj cov ntsiab, tom qab ntawd nrawm quenching los ua cov khoom siv supersaturated. Cov khoom cuav ntawm 150-200℃precipitates nanoscale theem zoo li mg₂si (hauv 6061) lossis al₂cumg (hauv 2024). Cov lus no cuam tshuam kev tshem tawm lub zog, nce tensile muaj zog txog 300% tiv thaiv anealed xeev.
Q4: Vim li cas yog 6061 alloy tsis dhau "txheej txheem txhuas"?
6061 (Al {- mg -} thu) ciaj sia), corrosion tsis kam, weldability, thiab machinability, thiab machinability. Nws lub T6 Tem yog qhov zoo tshaj plaws rau cov duab kos duab kos duab, cov thav duab marine, thiab tsheb chassis. Magnesium nyob ntsiag to precipitates muab hnub nyoog - tawv tawv} hardening, thaum chromium tswj cov nyom qoob loo. Nws yog 30% muaj zog dua 6063 extrusion alloy tab sis tswj tau zoo anodizing teb.
Q5: Dab tsi ua rau 7075 alloy's Ultra- lub zog siab?
7075 (Al - zag} mg {}}}}} CUTS 570 mpa η '(mgzn₂) precipitates. Zinc cov ntsiab lus (5.1 {- 6.1%) pab ua rau nag nag. Tooj kho cov kev ntxhov siab- corrosion tsis kam. Siv nyob rau hauv lub dav hlau spars thiab iav tub rog, nws yog 90% muaj zog dua 6061 tab sis tsawg dua corrosion-resistant, feem ntau xav tau Alclad txheej lossis anodizing.
