Aluminium-berylium master alloyyog ib qho khoom siv ntxiv uas yuav tsum tau ua rau cov smelting ntawm magnesium alloy thiab aluminium alloy. Thaum lub sij hawm melting thiab refining txheej txheem ntawm txhuas-magnesium alloy, magnesium lub ntsiab oxidizes ua ntej txhuas vim nws cov kev ua los tsim ib tug loj npaum li cas ntawm cov magnesium oxide zaj duab xis, uas ua rau ib tug loj npaum li cas ntawm inclusions nyob rau hauv lub txhuas alloy, uas cuam tshuam rau lub ingot zoo. thiab mechanical zog ntawm aluminium-magnesium alloy.
Beryllium hlau muaj lub vojvoog me me thiab muaj zog dua li magnesium. Nws oxidizes ua ntej magnesium ingot los tsim ib tug ntom oxide zaj duab xis los tiv thaiv cov hlau yaj. Hauv particular, beryllium nrog ib tug me me atomic loj tuaj yeem ua rau lub interatomic khoob ntawm qhov xoobmagnesium oxidezaj duab xis, ua rau cov zaj duab xis tuab thiab tiv thaiv cov oxidation txuas ntxiv ntawm magnesium, yog li tau txais cov khoom zoo aluminium-magnesium alloy.
Magnesium alloys feem ntau xav tau 8-20ppm, thiab aluminium alloys xav tau 8-15ppm. Nws cov haujlwm yog:
1. Txhim kho qhov huv, fluidity thiab corrosion kuj ntawm magnesium thiab txhuas;
2. Tiv thaiv oxidation thiab combustion ntawm magnesium thiab txhuas, thiab txo cov oxidation poob ntawm cov ntsiab lus;
3. Txhim kho cov txheej txheem ntawm cov hlau alloy, ua kom zoo dua cov nplej, thiab ua kom muaj zog.
Raws li kev xav tau ntawm cov sib txawv alloy ntxiv, cov ntsiab lus beryllium ntawmaluminium-berylium intermediate alloysFeem ntau suav nrog peb hom: AlBe1, AlBe3, thiab AlBe5.
1. Kev ua tau zoo thiab siv rau Aluminium beryllium master alloy:
Peb lub tuam txhab tsuas yog tsimaluminium-berylium master alloysmuaj 4.0-6.0% beryllium, uas yog siv rau beryllium ntxiv rau aluminium alloy smelting. Qhov sib ntxiv kub yog qhov tsawg thiab qhov poob ntawm beryllium tsawg. Cov yam ntxwv tseem ceeb ntawm aluminium-berylium master alloys yog siab zog, siab hardness, zoo corrosion kuj, thiab zoo heev hluav taws xob conductivity. Cov yam ntxwv no ua rau aluminium-berylium master alloys dav siv hauv aerospace teb. Piv txwv li, nws tuaj yeem siv los tsim cov dav hlau fuselages, cav, kiv cua thiab lwm qhov chaw, nrog rau cov qauv ntawm lub dav hlau xws li satellites thiab missiles. Tsis tas li ntawd, aluminium-beryllium master alloys kuj tuaj yeem siv los tsim cov tshuab tsheb, kev sib kis, nres tshuab thiab lwm yam, nrog rau cov khoom siv hluav taws xob, cov cuab yeej kho qhov muag thiab lwm yam.
Daim ntawv thov kev cia siab ntawm aluminium-berylium master alloy yog dav heev. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, tib neeg cov kev xav tau ntawm cov khoom siv hlau tau nce siab thiab siab dua. Raws li cov khoom siv hlau ua haujlwm siab, aluminium-berylium master alloy yuav raug siv rau hauv ntau qhov chaw. Nyob rau tib lub sijhawm, nrog kev txhim kho txuas ntxiv ntawm kev tsim cov thev naus laus zis, kev npaj nqi ntawm aluminium-berylium master alloy yuav maj mam txo qis, ua rau nws muaj kev sib tw ntau dua.
Aluminium-berylium master alloy yog ib qho tseem ceeb ntawm cov hlau alloy. Nws muaj zog thiab corrosion kuj thiab yog dav siv nyob rau hauv aerospace, tsheb tsim, electronics kev lag luam thiab lwm yam kev lag luam. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, daim ntawv thov kev cia siab ntawm aluminium-beryllium master alloy yuav dav dua.
2. Kev siv rau Aluminium beryllium master alloy:
1. Ci thiab qhuav ua ntej siv.
2. Ntxiv kub: saum 700 ℃.
3. Tus nqi ntawm cov khoom no yuav tsum tau ntxiv: Txiav txim siab raws li qhov tsim nyog raws li qhov kev xeem.
4. Ntxiv txoj kev: Tshem tawm cov slag thiab maj mam muab cov khoom no tso rau hauv cov kua txhuas. Tom qab melting, do tusyees thiab cia nws sawv ntsug rau 5 mus rau 10 feeb.
3. Ntim thiab cia rau Aluminium beryllium master alloy:
Cov khoom no yog nyob rau hauv daim ntawv thaiv nrog metallic luster thiab yog ntim rau hauv cardboard thawv. Khaws rau hauv qhov chaw ventilated thiab qhuav, deb ntawm noo noo.
