Al Sc alloy yog dab tsi? Dab tsi yog qhov kev tsim kho ntawm aluminium scandium alloy? Niaj hnub no, cov chaw tsim khoom ntawm aluminium scandium alloy yuav piav qhia txog kev tsim thiab kev loj hlob keeb kwm ntawm aluminium scandium alloy
Txij li thaum xyoo 1970, nrog kev siv zog tas li ntawm cov kws tshaj lij scandium hauv Suav teb, peb tau tsim peb tus kheej Al SC ntau lawm txoj kev thiab cov cuab yeej, uas tau txhawb kev tsim khoom thiab kev loj hlob ntawm Al SC. Tam sim no, Tuam Tshoj tau paub txog cov txheej txheem ntawm kev tsim A1 SC alloy, xws li txoj kev sib xyaw (sib tov melting method), molten ntsev electrolysis txoj kev thiab hlau (m lossis Mg) thermal txo txoj kev. Ntau yam, zoo thiab tso zis ntawm Al SC alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hauv ntau qhov chaw. Cov hauv qab no yog cov lus qhia luv luv rau cov khoom siv raw thiab cov khoom siv ntawm peb txoj kev loj, uas yog txoj kev sib xyaw, molten ntsev electrolysis txoj kev thiab hlau magnesium aluminium thermal txo txoj kev.
(1) The raw and auxiliary materials of the blending method are high-purity metal scandium (Sc) ≥ 9.9%, and blunt aluminum (A1) t>9.9 feem pua. Siv cov ntshiab argon (Ar) Ntau dua lossis sib npaug li 9.99 feem pua ) ua cov roj tiv thaiv.
(2) When the raw and auxiliary materials of molten salt electrolysis method use fluoride salt electrolyte (SCF3-LiF3-Sc: 0, system), use Sc 203 t>99% as raw material, and use LiF3I_- 99% and ScF3 t>99% are auxiliary materials. Molten aluminum (A1) is used as raw material, argon is used as protective gas (auxiliary material) in electrolysis, and graphite anode material is consumed. When using chloride electrolyte (SeC l. - KCl - NaCl, etc.), Se Cl3 ≥ 99% is the raw material, KCI and Na Cl are both i>99%, ArI>99.99% graphite anode, thiab lwm yam. Melt aluminium (A 1) ua raw khoom.
(3) Sc for raw and auxiliary materials of magnesium aluminum thermal reduction method: 03 I_- 99% is made of anhydrous SeCl3 I>99% raws li raw khoom. Nws yog melted nrog Na Cl thiab K CI los ua molten ntsev (S c Cl, - KCl - Na Cl), nrog NaCl thiab K Cl ua cov khoom pab, molten aluminium li alloy raw khoom, thiab magnesium (Mg) raws li tus neeg sawv cev txo. A r Ntau dua lossis sib npaug rau 9.99 feem pua yog cov roj tiv thaiv. Anhydrous Sc Cl tau npaj siv NH. C 1 Tiv thaiv Sc Cl thiab tsim S cOC l. Cov saum toj no Sc: 0, ScF, SeCI, thiab lwm yam yog tsim nyob rau hauv domestic nrog txaus mov. Lwm cov khoom siv pabcuam (KC I, Na Cl, Ar gas, thiab lwm yam) tuaj yeem yuav hauv tsev.
Aluminium alloy yog ib qho tseem ceeb engineering khoom siv rau kev lag luam hauv teb chaws thiab kev ruaj ntseg hauv teb chaws. Txawm li cas los xij, txog tam sim no, cov thev naus laus zis tseem ceeb rau kev npaj ntawm qee qhov kev ua haujlwm siab aluminium alloys hauv Suav teb tsis tau tawg. Ntau qhov kev ua tau zoo aluminium alloy cov ntaub ntawv xav tau los ntawm cov qauv tseem ceeb tseem cia siab rau kev xa khoom. Tseem muaj ntau txoj hauj lwm yuav tsum tau ua nyob rau hauv kev tshawb fawb thiab kev loj hlob ntawm high-kev ua tau zoo aluminium alloys.
