Txhuas muaj ntau lub zog zoo heev, Tab sis nws yog feem ntau yuav tsum tau ntxiv lwm yam hlau los txhim kho kev ua haujlwm thaum ua. Cov hlau twg tuaj yeem cuam tshuam cov khoom ntawm txhuas alloys? Muaj
Muaj yim cov hlau cov hlau xws li Vanadium, tshuaj ntxiv pob txha, hlau, lub thoob, kev thab hawm, neeg xaum hmoov, beryllium, thiab sodium.

Vim tias cov kev siv sib txawv ntawm lub tiav aluminium coil, Cov ntsiab lus ntxiv thaum lub sij hawm ua ntawm cov neeg tawg loj sib txawv, Cov qauv sib txawv, thiab sib txawv sib txawv tsim los ntawm txhuas, Yog li lawv cov teebmeem ntawm cov khoom ntawm txhuas alloys kuj sib txawv.

1. Cov Ntsiab Lus Hlau Hais: Tus cawv ntawm tooj liab ntsiab

Tooj liab yog ib qho tseem ceeb ua ke keeb kwm thiab muaj qee yam kev daws teeb meem zoo li cas. Ntxiv rau, Lub CUAL2 precipated los ntawm kev laus muaj qhov kev ua haujlwm tseem ceeb muaj zog. Cov ntsiab lus tooj liab nyob hauv lub phaj txhuas phaj feem ntau 2.5%-5%, thiab cov nyhuv muaj zog yog qhov zoo tshaj plaws thaum lub ntsiab lus tooj liab yog 4%-6.8%, Yog li cov ntsiab lus tooj liab ntawm cov tawv heev aluminium alloys yog nyob rau hauv no ntau.

2. Cov Ntsiab Lus Hlau Hais: tus cawv ntawm silicon

Al-MG2Si Alloy System Alloy Equilibrium Theem Diam duab Theem siab tshaj plaws ntawm MG2Si hauv Aluminium hauv Aluminium Hauv Aluminium Hauv Part Aluminium 1.85%, thiab deceleration kev txo qis nrog qhov txo qis ntawm qhov kub. Hauv lub deformed txhuas alloy, Qhov sib ntxiv ntawm silicon mus rau lub phaj txhuas yog txwv rau cov ntaub ntawv vuam, Thiab qhov sib ntxiv ntawm silicon kom aluminium kuj tseem muaj zog ntxiv dag zog.

3. Cov Ntsiab Lus Hlau Hais: Tus cawv ntawm magnesium

Kev txhawb nqa ntawm magnesium rau txhuas yog qhov zoo tshaj plaws. Rau txhua tus 1% Nce ntawm magnesium, Lub zog tensile nce txog li 34MPA. Yog tias tsawg dua 1% manganese tau ntxiv, Cov nyhuv dag zog yuav tau txhawb nqa. Yog li ntawd, Tom qab ntxiv manganese, Cov ntsiab lus magnesium yuav raug txo kom tsawg, thiab qhov nyiam ntawm kub tawg tuaj yeem txo tib lub sijhawm. Ntxiv rau, Manganese tuaj yeem ua rau MG5Al8 sib txuas prepipitate tusyees, thiab txhim kho lub corrosion tsis kam thiab vuam kev ua yeeb yam.

4. Cov Ntsiab Lus Hlau Hais: Tus ntawm manganese

Solubility siab tshaj plaws ntawm manganese hauv cov kev daws teeb meem yog 1.82%. Lub zog ntawm lub alloy nce tsis tu ncua nrog kev nce ntawm solubility, thiab elongation mus txog tus nqi siab tshaj plaws thaum lub ntsiab lus manganese yog 0.8%. Al-mn alloys yog ntev thiab luv hnub nyoog-hardening alloys, uas yog, lawv tsis tuaj yeem txhawb nqa los ntawm kev kho cua sov.

5. Cov Ntsiab Lus Hlau Hais: tus ntawm zinc

Lub solubility ntawm zinc hauv txhuas yog 31.6% Thaum Aluminium-nplua nuj ib feem ntawm Al-Zn Alloy System yog 275, thiab nws solubility poob rau 5.6% Thaum nws yog 125. Thaum zinc ntxiv rau txhuas ib leeg, kev txhim kho ntawm lub zog ntawm aluminium alloy yog qhov tsawg heev nyob rau hauv lub premise ntawm deformation, Thiab muaj ib tug nyiam ntawm kev ntxhov siab corrosion tawg thiab tawg, yog li txwv nws daim ntawv thov.

6. Cov Ntsiab Lus Hlau Hais: Tus Hlau Hlau Thiab Silicon

Hlau yog ntxiv raws li ib qho kev sib dhos hauv al-cu-mg-ni-rea wrouging aluminium alloy, Silicon hauv Al-MG-Si wrought aluminium, thiab hauv al-Si series vuam pas nrig thiab al-si weught alloy. Nyob rau hauv lwm alloys alloys, silicon thiab hlau yog hom impurity, uas muaj qhov cuam tshuam tseem ceeb ntawm kev ua yeeb yam ntawm cov alloy. Lawv nyob ib feem ntau yog fecl3 thiab dawb silicon. Thaum silicon loj dua li hlau, Cov β-fesial3 (lossis Fe2Si2al9) Theem yog tsim, Thiab thaum cov hlau loj dua li silicon, α-Fe2SiS8 (lossis FER3SI2AL12) yog tsim. Thaum qhov sib piv ntawm hlau thiab silicon tsis yog, Nws yuav ua rau cov kab nrib pleb hauv lub casting, thiab thaum cov hlau cov ntsiab lus nyob rau hauv lub cam leakes yog siab heev, Lub casting yuav ua brittle.

7. Cov Ntsiab Lus Hlau Hais: Cov nyhuv ntawm Titanium thiab Boron

Titanium yog ib feem ntau siv cov khoom ntxiv hauv aluminium alloys thiab ntxiv rau hauv daim ntawv ntawm Al-TI lossis Al-B tus tswv alloys alloys. Titanium thiab Aluminium Daim Ntawv Lub Tial2 Theem, uas dhau los ua cov tub ntxhais tsis muaj txiaj ntsig thaum lub sijhawm crystallization, thiab plays lub luag haujlwm hauv kev ua kom zoo forging qauv thiab weld qauv. Thaum Al-ti-based alloy muaj kev sib haum xeeb, Cov ntsiab lus tseem ceeb ntawm titanium yog hais txog 0.15%, Thiab yog tias muaj boron, lub deceleration yog me me li 0.01%.

8. Cov Ntsiab Lus Hlau Hais: Tus cawv ntawm chromium thiab strontium

Chromium cov ntaub ntawv intermetallic sib txuas xws li (Tus crfe)Al7 thiab (Vau)Al12 nyob rau hauv lub aluminium phaj, uas cuam tshuam lub nucleation thiab txoj kev loj hlob ntawm recrystallization, muaj qee yam ntxiv dag zog rau lub alloy, thiab tseem tuaj yeem txhim kho cov tawv ntawm cov alloy thiab txo qhov kev ua tau zoo rau kev ntxhov siab corrosion. . Txawm li cas los, lub quenching rhiab ntawm qhov chaw nce zuj zus, ua anodic oxide zaj duab xis daj. Qhov sib ntxiv ntawm chromium hauv txhuas alloy feem ntau tsis tshaj 0.35%, thiab txo qis nrog kev nce ntawm kev hloov pauv hauv cov alloy. Strontium yog ntxiv rau cov aluminium alloy rau extrusion by 0.015%. ~ 0.03% strontium, kom lub β-alfesi theem nyob rau hauv kev ingot ua tus neeg Suav tus cwj pwm-zoo li tus kheej-Alfesi theem, uas txo qhov nruab nrab lub sijhawm ntawm lub ingot los ntawm 60% rau 70%, Txhim kho cov khoom siv mechanical ntawm cov khoom siv thiab cov khoom siv yas ua haujlwm; txhim kho cov npoo av ntawm cov khoom.

Rau Silicon siab (10%Tom 13%) deformed txhuas alloys, ntxiv 0.02% ~ 0.07% strontium bas tuaj yeem txo cov Crystal thawj cov siv lead ua rau qhov tsawg kawg nkaus, thiab cov cuab yeej cuab tam tau tseem txhim kho. Lub zog tensile бb yog zoo dua los ntawm 233Mpa mus rau 236MPA, thiab cov txiaj ntsig ib lub zog б0.2 nce ntawm 204MPA rau 210MPA, elongation б5 nce ntawm 9% rau 12%. Qhov kev sib ntxiv ntawm kev ua kom lub hypeutectic al-Si alloy tuaj yeem txo qhov loj ntawm thawj cov siv lead ua silicon, Txhim kho kev ua haujlwm yas ua haujlwm, thiab tuaj yeem ntseeg tau kub-yob thiab txias-yob.
