Iyo doping nzira inzira yechinyakare yekunyungudikascandium yepakati alloys. Zvinosanganisira kuputira chimwe chikamu chepamusoro-kuchenasimbi scandiummuAruminiyamu, wozoisanganisa nealuminium yakanyungudutswa pasi pechidziviriro cheargon, ichiibata kwenguva yakakwana, ichiikurudzira kwazvo, nekuikanda musimbi kana inotonhora yemhangura mold kuti iwane.scandium yepakati alloys. Kunyunguduka kunogona kuitwa uchishandisa yakakwira-kuchena graphite kana alumina crucibles, uye nzira dzekudziya dzinogona kuitwa uchishandisa mavira ekupikisa kana epakati frequency induction furnaces. Iyi nzira inogona kunyungudutsa alloys epakati ane 2% kusvika 4%scandium.
Nheyo yeiyo doping nzira iri nyore, asi iyo inonyungudika yescandiumuye aruminiyamu inosiyana zvakanyanya (Sc is 1541 ℃, A1 iri 660 ℃). Iyo aruminiyamu inonyunguduka inoda kuwedzererwa kune tembiricha yakakwira, zvichiita kuti zviome kugadzirira zvigadzirwa zvepakati alloy zvine kugadzikana kuumbwa uye kugovera kwakafanana, uye zvakare zvakaoma kudzivirira kupisa kwe scandium. Kuti uite izvi, nzira yekuvandudza ndeyekusanganisa uye kudzvanya iyo yakakwira melting point metal scandium ine dispersant, aruminiyamu poda, flux, nezvimwewo pachine nguva panguva yekugadzirira, uye wozoawedzera musimbi yakanyungudutswa. Iyo dispersant inoora pakupisa kwepamusoro, ichipwanya otomatiki maagglomerates, ayo anogona kuburitsa yunifomu alloy uye kuderedza kupisa kwekupisa kweyepamusoro simbi inonyungudika. Asi zvakazara, mutengo wekugadzirirascandium yepakati alloyskushandisa kuchena kwepamusoroscandium simbisezvo mbishi zvinhu zvakakwirira, izvo zvakaoma kuti vashandisi veindasitiri vabvume.
