Indlela yedoping yindlela yemveli yokunyibilikascandium intermediate alloys.Kubandakanya ukusonga umlinganiselo othile wobunyulu obuphezuluiscandium yesinyithikwi-aluminiyam, emva koko ixutywe kunye ne-aluminium etyhidiweyo phantsi kokhuseleko lwe-argon, ibambe ixesha elaneleyo, ukuyivuselela ngokucokisekileyo, kwaye iphosa kwintsimbi okanye ukubumba ubhedu olubandayo ukufumanascandium intermediate alloys.Ukunyibilika kunokwenziwa kusetyenziswa igraphite ecocekileyo okanye iicrucibles ze-alumina, kunye neendlela zokufudumeza zingenziwa ngokusebenzisa iziko lokumelana okanye ii-medium frequency induction furnaces.Le ndlela inokunyibilikisa i-alloys ephakathi equlethe i-2% ukuya kwi-4%scandium.
Umgaqo wendlela ye-doping ilula, kodwa iindawo ezinyibilikayo zescandiumkunye ne-aluminiyam yohluka kakhulu (Sc yi-1541 ℃, i-A1 yi-660 ℃).I-aluminium inyibilika idinga ukugqithiswa kwiqondo lokushisa eliphezulu, okwenza kube nzima ukulungiselela iimveliso ze-alloy eziphakathi kunye nokwakheka okuzinzileyo kunye nokusabalalisa okufanayo, kwaye kunzima ukuphepha ukutshiswa kwe-scandium.Ukufezekisa oku, indlela yokuphucula ukuxuba kunye nokucinezela i-scandium yensimbi ephezulu yokunyibilika kunye ne-dispersant, i-aluminium powder, i-flux, njl. kwangaphambili ngexesha lenkqubo yokulungiselela, uze udibanise kwintsimbi etyhidiweyo.I-dispersant ibola kwiqondo lokushisa eliphezulu, ukutyumza ngokuzenzekelayo i-agglomerates, enokuvelisa i-alloy efanayo kunye nokunciphisa ilahleko evuthayo yentsimbi ephezulu yokunyibilika.Kodwa ngokubanzi, iindleko zokulungiselelascandium intermediate alloysusebenzisa ubunyulu obuphezuluintsimbi yescandiumnjengoko imathiriyeli ekrwada iphezulu ngokwentelekiso, ekunzima ukuba abasebenzisi bemizi-mveliso bayamkele.
