Aluminium-scandium alloyndi aluminiyamu yogwira ntchito kwambiri. Kuwonjezera pang'onoscandiumkwa aloyi zotayidwa akhoza kulimbikitsa mbewu kuyenga ndi kuonjezera kutentha recrystallization ndi 250 ℃ ~ 280 ℃. Ndiwonyezimira wambewu wamphamvu komanso woletsa zoletsa zopangira zitsulo zotayidwa, zomwe zimakhudza kwambiri kapangidwe kake ndi katundu wa alloy, kupititsa patsogolo mphamvu zake, kuuma, kuwotcherera, komanso kukana dzimbiri.Scandiumali ndi zabwino kubalalitsidwa kulimbikitsa zotsatira pa aluminiyamu, ndipo amasunga khola sanali recrystallized dongosolo mu mkhalidwe kutentha processing kapena annealing. Ma aloyi ena ndi mbale zoziziritsa kuzizira zokhala ndi mapindikidwe akulu, ndipo amasungabe dongosololi ngakhale atakulungidwa. The inhibitory zotsatira za scandium pa recrystallization akhoza kuthetsa dongosolo recrystallized mu kutentha okhudzidwa zone ya kuwotcherera, ndi subgrained dongosolo la masanjidwewo akhoza mwachindunji kusintha kwa kuponyedwa kapangidwe ka weld, kotero kuti zolumikizira zowotcherera za scandium munali. Aluminiyamu alloy ali ndi mphamvu zambiri komanso kukana dzimbiri. Kusintha kwa kukana kwa dzimbiri kwa ma aluminiyamu aloyi ndi scandium kumakhalanso chifukwa cha kuyengedwa kwa mbewu komanso kuletsa kwa njira ya recrystallization ndi scandium. Kuonjezera scandium kungapangitsenso kuti aluminiyamu alloy akhale ndi superplasticity yabwino. Pambuyo mankhwala superplastic elongation wa zotayidwa aloyi ndi pafupifupi 0.5%scandiumakhoza kufika 1100%. Chifukwa chake,aluminium-scandium aloyiakuyembekezeka kukhala m'badwo watsopano wa zida zopepuka zamapangidwe azamlengalenga, zandege, ndi zomanga zombo. Russia yapanga magiredi opitilira 10 a aloyi a aluminiyamu okhala ndi scandium, omwe amagwiritsidwa ntchito kwambiri pakuwotcherera zida zonyamula katundu muzamlengalenga, ndege, ndi zombo, komanso mapaipi a aluminiyamu aloyi zopangira zamchere zowononga media, akasinja amafuta anjanji, ndi makiyi. zigawo zomangira za masitima othamanga kwambiri.
Ma aluminiyamu okhala ndi scandium ali ndi mwayi wogwiritsa ntchito kwambiri m'magawo apamwamba kwambiri monga kupanga zombo, makampani apamlengalenga, maroketi ndi zoponya, ndi mphamvu zanyukiliya. Powonjezera kuchuluka kwa scandium, tikuyembekeza kuti mndandanda wa zida zatsopano za aluminiyamu zamtundu wamtundu wapamwamba kwambiri monga ultra-high-strength and high-toughness aluminium alloys, high-power-resistant corrosion aluminium alloys, ndi mphamvu zambiri. zitsulo zotayidwa za nyutroni zotsutsana ndi ma radiation zidzapangidwa pamaziko a ma aloyi omwe alipo. Ma alloys awa adzakhala ndi chiyembekezo chowoneka bwino chogwiritsa ntchito muzamlengalenga, mphamvu za nyukiliya, ndi mafakitale opanga zombo zapamadzi chifukwa chazinthu zake zabwino kwambiri. Atha kugwiritsidwanso ntchito pamagalimoto opepuka komanso masitima othamanga kwambiri. Chifukwa chake, zotayira za aluminiyamu zokhala ndi scandium zakhala zina zokopa maso komanso zopikisana kwambiri zamtundu wa aluminiyamu wochita bwino pambuyo pa ma aloyi a AlLi. dziko langa ndi lolemera muzinthu za scandium, ndipo lili ndi maziko ena a kafukufuku ndi kupanga mafakitale a scandium. China idakali wogulitsa kunja kwa scandium oxide. Kafukufuku paMa aloyi a AlScndizofunika kwambiri pakupanga zida za aluminiyamu zopangira zida zapamwamba komanso zachitetezo cha dziko langa. Itha kuperekanso sewero lathunthu pazabwino za scandium gwero la dziko langa ndikulimbikitsa chitukuko chamakampani a scandium ndi chuma cha dziko langa.
