Tam sim no, tib neeg siv ntau yam sib txawv ntawm cov khoom siv ntau yam. Tag nrho cov ntawm lawv muaj lawv tus kheej parameters thiab siv nyob rau hauv txawv industries. Nws tsim nyog xav txog cov yam ntxwv ntawm AD31T1, vim tias cov khoom siv no tau dhau los ua neeg nyiam heev hauv qee qhov chaw.

Kev piav qhia dav dav

Pib nrog, nws tsim nyog hais tias AD31T1 yog cov hlau uas muaj peb lub ntsiab lus tseem ceeb. Cov ntsiab lus no yog Mg-Al-Si hlau, nyob rau hauv lwm yam lus, nws yog ib tug alloy ntawm magnesium, txhuas thiab silicon. Raws li cov yam ntxwv AD31T1 belongs rau pawg ntawm deformable aircraft. Ntawm lwm cov ntaub ntawv zoo sib xws, nws piv tau zoo nyob rau hauv uas nws muaj ductility siab. Tsis tas li ntawd, nws muaj cov cuab yeej thev naus laus zis txaus txaus thiab siab tiv thaiv corrosion. Nws yuav tsum tau muab sau tseg tias no alloy lends nws tus kheej zoo rau xws li mechanical ua xws li stamping, dov, kos duab, thiab ntau lwm yam. Lub hom phiaj tseem ceeb ntawm cov khoom siv raw no yog kev tsim cov khoom siv nrog cov yam ntxwv zoo nkauj thiab cov npoo qis ntawm kev nyab xeeb.

Tshuaj piav qhia ntawm cov hlau

Cov yam ntxwv ntawm AD31T1 yog tswj hwm los ntawm GOST 4784-74. Qhov no alloy yog tsim los ntawm aluminium, qhov feem pua ntawm uas yog hais txog 99.3% ntawm tag nrho cov loj. Qhov seem 0.7% yog silicon thiab magnesium. Ntxiv rau lawv, cov khoom me me no kuj suav nrog titanium, hlau, zinc thiab manganese.

Piv txwv li, cov yam ntxwv ntawm AD31T1 sib txawv heev vim qhov tseeb tias cov hlau yog kwv yees li 0.5%. Vim li no, ductility thiab lub zog raug txo, vim qhov no tivthaiv tsim ntau yam intermetallic tebchaw. Txawm li cas los xij, nws ua, piv txwv li, txo qhov nyiam ntawm cov khoom tawg thaum lub sij hawm casting. Raws li rau manganese, nws muaj txiaj ntsig zoo ntawm cov khoom siv tiv thaiv corrosion, thiab tseem tshem tawm qhov poob ntawm lub zog ntawm cov hlau thaum laus.

Yog tias peb tham txog tag nrho cov npe feem pua ntawm cov tshuaj hauv cov hlau no, ces nws zoo li qhov no:

• hlau - txog li 0.5%;
• silicon ntawm 0.2 txog 0.6%;
• nyiaj manganese - txog 0, 1%;
• chromium cov ntsiab lus - mus txog 0.1%;
• titanium muaj me ntsis ntxiv - txog 0.15%;
• txhuas siv los ntawm 97.65 mus rau 99.35% ntawm tag nrho pawg pawg;
• tooj liab muaj ntau npaum li manganese;
• magnesium - los ntawm 0.45 txog 0.9%;
• zinc - mus txog 0.2%.

Thaum kawg, nws tsim nyog ntxiv tias cov yam ntxwv ntawm AD31T1 alloy nyob rau hauv cov ntsiab lus ntawm cov tshuaj tsis haum yog ze rau cov muaj pes tsawg leeg ntawm 6060 alloy, uas yog dav siv nyob rau hauv Western Europe.

Qhov txawv yog tias 6060 muaj hlau tsawg - los ntawm 0.1 txog 0.3%. Txawm li cas los xij, nws tsim nyogNco ntsoov tias qhov muaj nyob ntawm cov khoom siv no tsis muaj kev cuam tshuam rau cov khoom siv zoo.

Qhov zoo ntawm cov khoom siv

Yuav kom nkag siab qhov zoo ntawm cov hlau, nws yog qhov yuav tsum tau xav txog cov khoom tsim los ntawm nws.

Yog li, cov txiaj ntsig suav nrog cov yam ntxwv hauv qab no:

• Cov yam ntxwv ntawm AD31T1 txhuas ua kom ua tiav cov qauv muaj zog, uas tib lub sijhawm yuav hnyav me ntsis;
• khoom siv muaj suab nrov zoo;
• kev pab lub neej ntev txaus;
• siab corrosion kuj thiab zoo heev ductility;
• zoo nkauj zoo nkauj ntawm cov khoom;
• kev saib xyuas yooj yim, uas yog qhov tsis xav tau kev saib xyuas zoo;
• dav dav rau kev tsim cov khoom tsim qauv tsim nyog.

Txawm li cas los xij, cov yam ntxwv ntawm aluminium alloy Ad31T1 muaj lawv qhov tsis muaj zog. Ntawm lawv, nws yog ib qho tsim nyog yuav tsum tau hais tias cov yas siab nyob ze ciam teb ntawm qhov siab ntawm deformation, uas yuav pom tshwj xeeb tshaj yog thaum qhov kub thiab txias txo qis. Qhov no tuaj yeem ua rau nws nyuaj rau kev thauj khoom.

Daim ntawv thov ntawm alloy

Txawm tias nws qhov tsis txaus, cov khoom siv no tau siv dav.

Nws yog ib txwm siv los tsim cov txhuas profile. Kwv yees li 57% ntawm tag nrho cov khoom tsim los ntawm cov hlau no. Lawv muaj peev xwm sib tw zoo kawg nkaus nrog galvanized steel, xws lisiab tiv thaiv corrosion yog pom nyob rau hauv ob qho tib si cov ntaub ntawv, tab sis cov aluminium alloy tsis xav tau ib ntus daim ntawv thov ntawm ib tug tiv thaiv txheej, tsis zoo li steel.

Vim muaj ntau qhov zoo, cov khoom siv tau zoo rau kev tsim cov kav dej. Cov yam ntxwv ntawm AD31T1, xws li siab corrosion kuj thiab non-toxicity, tau ua rau lub fact tias cov alloy tau nrov heev nyob rau hauv kev tsim cov thawv. Feem ntau lawv yog siv los thauj nitric acid, organic teeb meem lossis txawm tias cov zaub mov. AD31T1 kuj tseem siv los tsim cov ntawv ci siv rau cov kaus poom thiab tetrapacks.

Tsis ntev los no, cov khoom siv no tau nce ntxiv hauv kev tsim cov cables sib txuas lus, nrog rau cov khoom siv hluav taws xob. Qhov no tau ua tiav vim qhov tseeb tias nws muaj cov npoo ntawm kev nyab xeeb ntau dua li cov tooj liab uas tau siv ua ntej. Kev siv AD31T1 alloy ua rau nws muaj peev xwm ua kom qhov loj me ntawm qhov ntev, nrog rau txo qhov kev puas tsuaj thaum lub sij hawm teeb tsa ntawm kab, uas tshwm sim ntau zaus. Hais txog hluav taws xob conductivity, cov khoom siv thib ob tam sim ntawd tom qab tooj liab, tab sis tib lub sijhawm nws tus nqi yog kwv yees li 1.5 npaug qis. Tsis tas li ntawd, aluminium yog qhov sib dua, uas ua lub luag haujlwm tseem ceeb hauv kev sib dhos ntawm cov khoom sib dhos, uas yuav tsum muaj ntau cov ntsiab lus uas ua haujlwm tam sim no.

Kaum ntawm AD31T1

Cov kaum ntawm AD31T1 kuj tau nrov heev. Cov yam ntxwv ntawm cov hlau no tau ua rau cov txiaj ntsig hauv qab no.

Wo-Ua ntej, lub teeb yuag ntawm cov ces kaum ua rau nws tuaj yeem txo qhov hnyav ntawm tus ncej thaum nws tsim. Qhov thib ob, plasticity thiab yooj yim ntawm kev ua haujlwm ua lub luag haujlwm tseem ceeb, vim tias koj tuaj yeem hloov cov duab nrog cov cuab yeej siv tes yog tias tsim nyog, thiab tom qab vuam me me thiab zoo huv si yuav nyob twj ywm. Tsis tas li ntawd, muaj kev tiv thaiv siab rau ntau yam kev cuam tshuam ib puag ncig, nrog rau oxidation. Qhov no ua rau kom muaj zog ntawm cov ces kaum, uas yog ib qho tseem ceeb ntawm kev tsim kho ntawm tib lub thav duab.

Cov ces kaum siv rau

Raws li nws tau dhau los ua qhov tseeb, qhov tseem ceeb ntawm cov khoom no yog kev tsim kho. Txawm li cas los xij, muaj cov npe loj ntawm cov yam ntxwv zoo ua rau nws siv tau rau lwm lub hom phiaj. Txhuas cov ces kaum ua los ntawm AD31T1 alloy yog zoo heev rau kev tsim ib tug ncej rau drywall. Lawv feem ntau siv rau hauv cov txheej txheem rooj tog sib dhos.

Alloys AD31T1 thiab 6063

Nyob rau hauv xaus, nws yog tsim nyog sau cia hais tias muaj ib tug American-ua analogue - alloy 6063. Lub ntsiab coincidence yog hais tias ob lub ntsiab alloying ntsiab yog silicon thiab magnesium. Tus nqi ntawm thawj lub caij tuaj yeem yog los ntawm 0.2 txog 0.6%, thiab qhov thib ob - tib yam li hauv AD31T1: 0.45-0.9%. Txawm li cas los xij, muaj qhov sib txawv me ntsis, uas yog tias 6063 siv chromium hloov titanium. Nyob rau hauv tas li ntawd, cov alloy belongs rau cov pab pawg neeg ntawm nruab nrab lub zog, tab sis nyob rau tib lub sij hawm, thaum lub sij hawm lub sij hawm ntawm thermalKev ua haujlwm tuaj yeem txhim kho cov khoom zoo, nrog rau AD31T1.
