Ntshiab scandium hmoov yog siv los ua additive thiab hloov kho hauv cov ntaub ntawv alloy. Qhov sib ntxiv ntawm Sc rau aluminium thiab aluminium alloys tuaj yeem txhim kho cov khoom zoo ntawm cov alloys. Piv txwv li, lub zog, hardness, kub tsis kam, corrosion kuj thiab weldability ntawm alloy yog obviously txhim kho. Yog tias Sc Tsawg dua lossis sib npaug rau {{{0}}.4 feem pua yog ntxiv rau Al, Al3Sc theem tshiab tuaj yeem tsim los kho cov qauv hlau, nce qhov kub ntawm recrystallization los ntawm 150~2 00 degree , thiab txhim kho lub zog, hardness thiab kub tsis kam ntawm cov hlau. Yog tias Sc0.75 feem pua yog ntxiv rau Al Mg Zr, Al Si Mg Zr alloy yog tsim, thiab nws cov kev ua tau zoo dua. Yog tias Sc0.3 ~ 1.0 feem pua yog ntxiv rau A1 Li Mg Zr, cov hlau muaj cov khoom zoo dua.
Cov saum toj no A1 SC alloy tseem tuaj yeem tiv thaiv embrittlement thaum ua haujlwm ntawm qhov kub siab ntev ntev. Yog li ntawd, nws tuaj yeem siv los ua cov khoom siv zoo heev, thiab tau siv dav hauv aerospace, aviation, missile, tsheb thiab nkoj cov khoom siv, uas yog lub peev xwm loj ntawm A1 SC cov hlau tshiab.
Tsis tas li ntawd, tom qab ntxiv Sc, lub zog tensile ntawm AI Mg ({{0}}}.1) - Sc (O.4 feem pua) alloy tom qab kev laus kev kho mob yog nce los ntawm 20.35 feem pua, qhov txaus txwv yog nce los ntawm 60.80 feem pua, thiab elongation yog nce 20.25 feem pua. Raws li nyob rau hauv alloy MgY (11 feem pua) Tom qab ntxiv Sc1l feem pua rau Mn (0.6 feem pua), qhov kev txwv ntws yog 60-80Pa tom qab kev laus kho ntawm 300 degree . Yog tias Sc ntxiv rau hauv GaSc, nws tuaj yeem ua rau hauv cov ntaub ntawv zoo heev thiab cov khoom siv txheej txheej.
Piv txwv li, tom qab ntxiv Sc rau TnC, nws hardness nce mus ze rau ntawm pob zeb diamond. Yog tias ScB2 yog tsim los tom qab ntxiv Sc rau boron, nws tuaj yeem siv los ua lub teeb kub-resistant alloy thiab cathode tivthaiv rau cov phom electron.
