Aluminium Alloy e sebetsang ka holimo: Al-Sc Alloy
Al-Sc alloy ke mofuta oa motsoako oa aluminium o sebetsang hantle haholo. Ho na le litsela tse 'maloa tsa ho ntlafatsa ts'ebetso ea motsoako oa aluminium, oo har'a oona ho matlafatsang le ho matlafatsa micro-alloying ke sebaka sa moeli oa lipatlisiso tse phahameng tsa aluminium lilemong tsa morao tjena tsa 20.
Sebaka se qhibilihang sa scandium ke 1541 ℃, 'me sa aluminium ke 660 ℃, kahoo scandium e tlameha ho eketsoa ho alloy alloy ka mokhoa oa master alloy, e leng thepa ea bohlokoa bakeng sa ho lokisa motsoako oa aluminium o nang le scandium. Ho na le mekhoa e 'maloa ea ho lokisa li-alloys tse kholo, tse kang mokhoa oa doping, scandium fluoride, mokhoa oa ho fokotsa mocheso oa tšepe ea scandium oxide, mokhoa oa ho qhibiliha oa letsoai la electrolysis joalo-joalo. “
Mokhoa oa doping ke ho eketsa ka ho toba tšepe ea scandium ho alloy aluminium, e theko e boima, tahlehelo e tukang ts'ebetsong ea ho qhibiliha le litšenyehelo tse phahameng tsa master alloy.
Toxic hydrogen fluoride e sebelisoa ha ho etsoa scandium fluoride ka mokhoa oa tšepe oa ho fokotsa mocheso oa scandium fluoride, o nang le lisebelisoa tse rarahaneng le mocheso o phahameng oa ho fokotsa mocheso oa tšepe.
Sekhahla sa ho hlaphoheloa ha scandium ka tšepe ea ho fokotsa mocheso oa scandium oxide ke 80% feela;
Sesebelisoa sa electrolysis ea letsoai le qhibilihisitsoeng se rarahane 'me sekhahla sa phetoho ha se phahame.
Kamora ho bapisa le ho khetha, ho loketse haholo ho lokisa Al-Sc master alloy ka ho sebelisa ScCl letsoai le qhibilihisitsoeng Al-Mg mokhoa oa ho fokotsa mocheso.
Lisebelisoa:
Ho kenyelletsa trace scandium ho alloy ea aluminium ho ka khothaletsa ntlafatso ea lijo-thollo le ho eketsa mocheso oa recrystallization ka 250.℃~ 280℃. Ke sehloekisi se matla sa lijo-thollo le inhibitor e sebetsang ea recrystallization bakeng sa alloy ea aluminium, e nang le tšusumetso e hlakileng ho th.e sebopeho le thepa ea alloy le ho ntlafatsa haholo matla a eona, boima, weldability le ho hanyetsa kutu.
Scandium e na le phello e ntle e matlafatsang ea ho hasana ho aluminium, 'me e boloka mohaho o tsitsitseng o sa kang oa tsosolosoa ts'ebetsong e chesang kapa ea annealing. Li-alloys tse ling ke lishiti tse kolobisitsoeng tse batang tse nang le deformation e kholo, tse ntseng li boloka sebopeho sena le kamora ho ts'oaroa. Thibelo ea scandium ho recrystallization e ka felisa sebopeho sa recrystallization sebakeng se amehileng ke mocheso oa weld, Sebopeho sa subgrain sa matrix se ka fetisetsoa ka kotloloho ho sebopeho sa chese ea weld, se etsang hore lenonyeletso le cheselitsoeng la alloy ea aluminium e nang le scandium e be le. matla a phahameng le ho hanyetsa ho bola.
Phello ea scandium holim'a ho hanyetsa ha kutu ea aluminium alloy e boetse e bakoa ke ntlafatso ea lijo-thollo le ho thibela ts'ebetso ea recrystallization.
Ho eketsoa ha scandium ho ka boela ha etsa hore motsoako oa aluminium o be le superplasticity e ntle, 'me bolelele ba motsoako oa aluminium ka 0.5% scandium bo ka fihla 1100% ka mor'a phekolo ea superplastic.
Ka hona, Al-Sc alloy e lebelletsoe ho fetoha moloko o mocha oa lisebelisoa tsa sebopeho se bobebe bakeng sa indasteri ea sefofane, sefofane le likepe, tse sebelisoang haholo bakeng sa likarolo tsa sebopeho sa sefofane, sefofane le sekepe, liphaephe tsa alloy tsa aluminium bakeng sa tikoloho e senyang ea alkaline, litanka tsa oli tsa terene, likarolo tsa bohlokoa tsa meralo ea literene tse lebelo, joalo-joalo
Tebello ea kopo:
Sc-containing aluminium alloy e na le tebello e pharaletseng ea ts'ebeliso mafapheng a theknoloji e phahameng joalo ka likepe, indasteri ea sefofane, rokete le missile, matla a nyutlelie, joalo-joalo Ka ho eketsa trace scandium, ho na le tšepo ea ho hlahisa letoto la ts'ebetso e phahameng ea moloko o mocha. lisebelisoa tsa motsoako oa aluminium tse thehiloeng holim'a motsoako o teng oa aluminium, joalo ka matla a phahameng haholo le alloy ea aluminium e thata haholo, matla a phahameng. Aluminium e thibelang ho bola, alloy ea matla a phahameng a nyutrone e hanyetsanang le mahlaseli a aluminium joalo-joalo. Li-alloys tsena li tla ba le tebello e khahlang haholo ea ts'ebeliso ea liindasteri tsa sepakapaka, matla a nyutlelie le kaho ea likepe ka lebaka la thepa ea tsona e pharalletseng, hape e ka sebelisoa le likoloing tse bobebe. le literene tsa lebelo le holimo. Ka hona, motsoako oa aluminium o nang le scandium o fetohile o mong o khahlehang le oa tlhōlisano o phahameng ka ho fetisisa oa aluminium alloy alloy structural material ka mor'a AlLi alloy.China e na le lisebelisoa tse ngata tsa scandium 'me e na le motheo o itseng oa lipatlisiso tsa scandium le tlhahiso ea indasteri, e ntseng e le morekisi ea ka sehloohong oa scandium oxide. Ke bohlokoa ba nako e telele ho nts'etsapele lisebelisoa tsa alloy tsa aluminium bakeng sa kaho ea theknoloji e phahameng le ea naha naheng ea China, 'me AlSc e ka fana ka papali e felletseng molemong oa lisebelisoa tsa scandium naheng ea China le ho khothaletsa nts'etsopele ea indasteri ea scandium le moruo oa naha Chaena. .
