A: Aluminium nyob rau hauv nws daim ntawv elemental yog ib tug ncaj mos mos thiab lub teeb yuag hlau thiab yog feem ntau alloyed nrog tooj liab, magnesium, tin los yog zinc kom nws lub zog, durability, loj thiab workability. Txog 85% ntawm aluminium alloys yog siv rau wrought khoom. Aluminium alloys tau yooj yim ua haujlwm. Cam khwb cia txhuas cov khoom yog tus nqi qis vim nws qhov qis melting point, tab sis lawv muaj zog tensile qis. Aluminium alloys yog dav siv nyob rau hauv engineering daim ntaub ntawv thiab cov khoom uas lub teeb yuag thiab tsis kam mus corrosion yuav tsum tau. Aluminium alloys yog siv nyob rau hauv aerospace tej yaam num, automotive engine Cheebtsam, shipbuilding thiab lwm yam dej qab ntsev daim ntaub ntawv. Aluminium alloys yuav warp ntawm qhov kub thiab txias thiab tsis zoo li hlau, tsis txhob ci liab ua ntej melting. Aluminium alloys tseem muaj qhov txo qis qis dua li cov hlau thiab yuav ua rau tsis muaj zog ntxiv nrog kev ntxhov siab ntxiv. Lawv tsis tshua muaj siv nyob rau hauv fabrication daim ntaub ntawv uas yuav tsum tau siab qaug zog tus nqi.

A: Nws yog pre-alloyed sib tov ntawm alloying ntsiab. Nws tseem yog lub npe hu ua ib qho ntawm cov kev hloov kho, hardeners, lossis grain refiners raws li lawv daim ntawv thov. Yttrium-Aluminium Alloy (Y-Al Alloy) yog ntxiv rau yaj kom ua tiav qhov xav tau.

A: Aluminium-erbium yog ib qho ntawm ntau lub siab purity tsawg lub ntiaj teb alloys tsim los ntawm American Elements. Raws li tus tswv alloy, aluminium-erbium tuaj yeem siv rau cov nplej refining, hardening, thiab txhim kho txhuas kev ua tau zoo los ntawm kev txhim kho cov khoom xws li ductility thiab machinability. Cov ntaub ntawv hlau muaj xws li cov nplooj ntawv thiab daim hlau, discs, foils, rods, raj, thiab lwm yam duab.

A:

• Hardeners: Siv rau kev txhim kho lub cev thiab lub zog ntawm cov hlau alloys.
• Grain Refiners: Siv rau kev tswj cov dispersion ntawm ib tug neeg muaju nyob rau hauv cov hlau los tsim ib tug finer thiab ntau uniform grain qauv.
• Modifiers & Tshwj xeeb Alloys: Feem ntau siv los ua kom muaj zog, ductility, thiab machinability.

A: Aluminium cerium alloys muaj ntau yam khoom tsim nyog, suav nrog:

• Siab ductility
• Zoo castability
• Siab kam rau ua qhov tsis xws luag
• Exceptional high-temperature mechanical khoom khaws cia
• Robust room-temperature mechanical zog

A: Yttrium thiab aluminium react los tsim eutectic sib tov. Qhov sib ntxiv ntawm yttrium kuj tuaj yeem:

• Txo qhov luaj li cas ntawm cov as-cast alloy
• Nce tus nucleation piv
• Txhim khu lub zog ntawm Al-Zn-Mg-Cu alloy ntawm qhov kub thiab txias
• Txhim kho lub zog ntawm T6 tempered Al-Cu-Mg-Ag alloys ntawm 300 degree

A: Aluminium alloys feem ntau tiv taus corrosion. Lawv tiv taus corrosion nyob rau hauv cov huab cua, nyob rau hauv marine, nroog, thiab industrial cheeb tsam. Lawv kuj tiv taus corrosion nyob rau hauv ib puag ncig sib txawv thiab cov tshuaj lom neeg.

Aluminium alloys tiv thaiv corrosion vim lawv tsim ib txheej oxide nyias uas tiv thaiv corrosion ntxiv. Cov txheej oxide no hu ua aluminium oxide lossis Al2O3.

A: Qhov cuam tshuam ntawm cov ntsiab lus alloying ntawm aluminium alloy corrosion

1. Cov nyhuv ntawm Mg

Mg ntxiv rau aluminium alloy los txhim kho cov khoom siv kho tshuab. Mg txo tus nqi ntawm cov tshuaj tiv thaiv cathodic thaum tam sim no nyob rau hauv cov khoom tov (vim tsis tshua muaj pauv tam sim no ntom ntawm Mg) thiab ua rau corrosion kuj.

2. Cov nyhuv ntawm Si

Si yog ntxiv nrog Mg tsim Mg2Si precipitate uas txhim khu cov aluminium alloy hardness tab sis ua rau hauv zos corrosion. Ntxiv Si ntau dhau yuav ua rau muaj kev ntxhov siab corrosion tawg vim Si tshwm ntawm ciam teb thiab ua kom cov tshuaj tiv thaiv cathodic.

3. Cov nyhuv ntawm Cu

Zoo ib yam li Mg, lub xub ntiag ntawm Cu ua rau cov aluminium alloy tsim cov tshuaj tiv thaiv cathodic hauv zos uas ua rau corrosion. Txawm li cas los xij, 600 lossis 700 series alloys lub hom phiaj tseem ceeb ntawm kev ntxiv Cu rau qhov muaj pes tsawg leeg rau kev ntxiv dag zog lub hom phiaj, tsis yog rau lub hom phiaj tiv thaiv corrosion.

4. Cov nyhuv ntawm Zn

Ntxiv Zn rau aluminium alloy yuav tsim τ theem Al-Mg-Zn es tsis txhob theem Al3Mg2, uas ua rau muaj kev ntxhov siab corrosion tawg. Alloys siv nyob rau hauv aerospace kev lag luam tseem siv Zn los ua ib tug hardness-enhanced precipitate.

5. Cov nyhuv ntawm Fe

Hauv cov txheej txheem tsim khoom, aluminium alloy feem ntau sib xyaw Fe rau hauv cov khoom sib xyaw. Cov txheej txheem Fe tshem tawm yog kim heev. Fe tsis yooj yim rau yaj hauv cov hlau thiab tswj cov tshuaj tiv thaiv cathodic, ua rau txo qis corrosion. Fe ua ke nrog Mn lossis Cu hauv cov hlau kuj yog qhov tseem ceeb tiv thaiv corrosion.

6. Cov nyhuv ntawm Mg

Xws li Manganese nyob rau hauv aluminium alloy yuav txo Fe concentration thiab nce corrosion kuj. Txawm li cas los xij, yog tias Mn ntau tshaj qhov kev txwv tsis pub solubility (1.25% los ntawm qhov hnyav), nws yuav ua rau tsim Al6Mn, uas ua rau cov tshuaj tiv thaiv cathodic thiab ua rau muaj teeb meem corrosion.

7. Cov nyhuv ntawm Li

Lithium plays lub luag hauj lwm ntawm nce aluminium alloy hardness, yog li Al-Li alloy yog dav siv nyob rau hauv aviation teb. Txawm li cas los xij, Li tau tshwm sim raws li thaj tsam ntawm cov qoob loo, ua rau muaj kev txhim kho sai ntawm corrosion thiab hauv zos kis ntawm corrosion.

A: Aluminium-Erbium alloys yog ib qho ntawm cov khoom siv rov ua dua tshiab thiab tuaj yeem rov ua dua tshiab tsis tas yuav poob nws cov khoom. Recycling aluminium txuag 95% ntawm lub zog siv los tsim nws los ntawm cov khoom siv raw.
