Indlela ye-doping iyindlela yendabuko yokuncibilikaama-alloys aphakathi kwe-scandium. Kubandakanya ukugoqa ingxenye ethile yobumsulwa obuphezului-metal scandiumku-aluminium, bese uyixuba ne-aluminium encibilikisiwe ngaphansi kwesivikelo se-argon, uyibambe isikhathi esanele, uyigoqe kahle, bese uyiphonsa esikhunjini sensimbi noma esibandayo sethusi ukuze uthole.ama-alloys aphakathi kwe-scandium. Ukuncibilika kungenziwa kusetshenziswa i-high-purity graphite noma i-alumina crucibles, futhi izindlela zokufudumeza zingenziwa ngokusebenzisa iziko lokumelana noma iziko lokungeniswa kwemvamisa ephakathi. Le ndlela ingancibilikisa ama-alloys aphakathi nendawo aqukethe u-2% kuya ku-4%scandium.
Isimiso sendlela ye-doping silula, kodwa amaphuzu ancibilikayo wescandiumfuthi i-aluminium ihluke kakhulu (i-Sc ingu-1541 ℃, i-A1 ingu-660 ℃). Ukuncibilika kwe-aluminium kudinga ukushiswa ngokweqile ekushiseni okuphezulu, okwenza kube nzima ukulungisa imikhiqizo ye-alloy ephakathi ngokubunjwa okuzinzile nokusabalalisa okufanayo, futhi kunzima nokugwema ukushiswa kwe-scandium. Ukufeza lokhu, indlela yokuthuthukisa ukuxuba nokucindezela i-scandium yensimbi ephezulu yokuncibilika nge-dispersant, i-aluminium powder, i-flux, njll kusengaphambili ngesikhathi senqubo yokulungiselela, bese uyifaka ensimbi encibilikisiwe. I-dispersant ibola ekushiseni okuphezulu, ngokuzenzakalelayo ukuchoboza ama-agglomerates, okungakhiqiza i-alloy efanayo futhi kunciphise ukulahlekelwa okuvuthayo kwensimbi ephezulu yokuncibilika. Kodwa sekukonke, izindleko zokulungiselelaama-alloys aphakathi kwe-scandiumngokusebenzisa ubumsulwa obuphezuluscandium metalnjengoba impahla eluhlaza iphezulu uma kuqhathaniswa, okunzima ukuthi abasebenzisi bezimboni bakwamukele.
