Aluminium scandium alloy

Scandiumyog lub caij hloov pauv thiab ib qho ntawm lub ntiaj teb tsis tshua muaj neeg. Nws muaj cov khoom zoo heev xws li muag muag, nquag tshuaj lom neeg cov khoom siv, kev ua haujlwm siab thiab qhov tshwj xeeb lub ntiajteb txawj nqus. Thaum ntxiv rau aluminium alloys, nws tuaj yeem txhim kho lub zog, kev nruj thiab lwm yam khoom ntawm cov alloys. Nws yog hom tshiab ntawm cov kab cim rau kev txhim kho lub siab, muaj kub-kub-resistant thiab high-corrosion-resistant aluminium alloys. Txij li thaum lub ntsiab lus melting ntawm scandium yog heev, ntawm 1541 ° C, yog li scandium yuav tsum tau ntxiv rau cov txhuas alloy nyob rau hauv daim ntawv ntawm ib qho kev sib txuam. Yog li ntawd, tusAluminium-Scandium Intermediate Alloyyog cov khoom siv tseem ceeb rau kev npaj ntawmAluminium-scandium alloys.

Ntxiv cov kab tawm ntawm scandium (0.15 ~ 0.5WT%) kom aluminium alloys tuaj yeem ua lub luag haujlwm zoo. Ua ntej, nws tuaj yeem ua kom paub cov nplej ntawm cov nplej alloys alloys thiab yog lub haib grain refiner rau txhuas alloys. Thib ob, nws tuaj yeem nce cov recrystallization kub txog 250 ℃, tshem tawm cov qauv txheej txheem ntawm WELD, thiab txhim kho cov qauv kub ua kom tsis txhob muaj kev tawg rog thiab txhim kho cov rog kub ua rau muaj kev tawg rog kub hnyiab tau ntawm cov alloy alloy. Nws yog qhov zoo recrystallization inhiborization rau txhuas alloys thiab muaj ib qho kev ua tau zoo, lub zog ua haujlwm, corrosion tsis kam thiab tiv taus neutron hluav taws xob puas tsuaj. Tam sim no, nws tau paub tias lub zog ntawmaluminium-scandium alloytuaj yeem ncav cuag ntau dua 750MPA, thiab Elastic Modulus tuaj yeem tshaj 100gpa, uas yog 30% siab dua li ntawm cov tsoos alloys. Thib peb, nws tuaj yeem ua lub luag haujlwm zoo hauv kev rho tawm zuj zus, tswj kev ua haujlwm ruaj khov lossis muaj cov yam ntxwv ntawm kev ua haujlwm kub thiab txias thermal. Plaub, nws tuaj yeem ua cov alloys alloys muaj zoo superplasticity. Tom qab kho superplastic, lub elongation ntawm txhuas alloys nrog txog 0.5% scandium ntxiv tuaj yeem ncav cuag 1100%.

Raws li cov kws kho mob zoo tshaj plaws ntawm txhuas-scandium alloys tau hais los ntawm cov khoom siv zoo heev, thiab tseem tswj hwm cov khoom lag luam zoo heev xws li cov teb chaws Europe thiab Tebchaws Asmeskas. Aluminium-scandium alloys yog ib hom kev ua tau zoo tshiab aluminium alloy nrog siab zog, thiab lub teeb hnyav. Lawv yog cov ntaub ntawv zoo tshaj plaws rau cov txheej txheem dav hlau, cov ntaub ntawv tsheb kauj vab, thiab cov tub rog kev lag luam tshiab xws li lub nkoj, kev siv zog ua tub rog thiab cov khoom siv hluav taws xob, thiab riam phom. Lawv feem ntau yog siv rau kev tso vuam thauj khoom-cov kab hlau, thiab cov nkoj roj av alkaline, thiab cov tsheb ciav hlau tseem ceeb ntawm cov tsheb ciav hlau siab. Lawv tau siv dav hauv Aerospace, tsheb thauj mus los, kev lag luam nuclear, electronics, ntim ntim, thiab lwm thaj chaw.

Tam sim no, muaj ntau tshaj ib txhiab hom ntawm txhuas cov ntaub ntawv hauv ntiaj teb, uas tau ua tiav rau tib neeg kev nce qib. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm cov qauv kev ua neej, Kuv lub teb chaws yog qhov kev xav tau ceev ceev ntawm kev loj hlob tshiab cov kev ua tau zoo aluminium alloys. Kev loj hlob ntawm tus nqi qis scandium-txhuas cov khoom nruab nrab tuaj yeem tso cov ntaub ntawv kev lag luam zoo, thiab txhawb kev lag luam ntawm kuv lub teb chaws txhuas kev lag luam txhuas nrog kev lag luam txhuas kev lag luam thoob ntiaj teb. Yog li ntawd, txoj haujlwm npaj ntawm txhuas-scandium (nruab nrab) alloy yog qhov tseem ceeb ntawm kev txhim kho cov ntaub ntawv txhuas alloib hauv lub neej yav tom ntej.
