(1) Amandla nobulukhuni be-magnesium polycrystals ehlanzekile akuphezulu.Ngakho-ke, i-magnesium ehlanzekile ayikwazi ukusetshenziswa ngokuqondile njengento yesakhiwo.I-magnesium ehlanzekile ivame ukusetshenziselwa ukulungisa ama-alloys e-magnesium namanye ama-alloys.
(2) Ingxubevange yeMagnesium iyinto yobunjiniyela obuluhlaza enamandla okuthuthuka nokusetyenziswa kwekhulu lama-21.
I-Magnesium ingakha ama-alloys nge-aluminium, ithusi, i-zinc, i-zirconium, i-thorium nezinye izinsimbi.Uma kuqhathaniswa ne-magnesium ehlanzekile, le alloy inezakhiwo ezingcono zemishini futhi iyinto enhle yesakhiwo.Nakuba ama-alloys e-magnesium enziwe anezakhiwo ezinhle ezihlanganisayo, i-magnesium iyi-lattice ene-hexagonal eseduze, okunzima ukuyicubungula ngokwepulasitiki futhi inezindleko eziphezulu zokucubungula.Ngakho-ke, inani lamanje lama-alloys e-magnesium enziwe lincane kakhulu kune-cast magnesium alloys.Kukhona inqwaba yezakhi kuthebula le-periodic ezingakha ama-alloys nge-magnesium.I-Magnesium nensimbi, i-beryllium, i-potassium, i-sodium, njll. ayikwazi ukwakha ama-alloys.Phakathi kwezakhi zokuqinisa i-magnesium alloy, ngokusho kwethonya lezakhi ze-alloying kuzakhiwo zemishini yama-alloys kanambambili we-magnesium, izakhi ze-alloying zingahlukaniswa ngezigaba ezintathu:
1. Izakhi ezithuthukisa amandla yilezi: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
2. Izakhi ezithuthukisa ukuqina yizi: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
3. Izinto ezithuthukisa ukuqina ngaphandle koshintsho olukhulu emandleni: I-Cd, i-Ti, ne-Li.
4. Izakhi ezandisa kakhulu amandla futhi zinciphise ukuqina: Sn, Pd, Bi, Sb.
Umthelela wezakhi zokungcola ku-magnesium
A. Ukungcola okuningi okuqukethwe ku-magnesium kunemiphumela emibi kuzakhiwo zemishini ze-magnesium.
B. Uma i-MgO idlula i-0.1%, izakhiwo zemishini ze-magnesium zizoncishiswa.
Uma okuqukethwe kwe-C no-Na kudlula u-0.01% noma okuqukethwe kwe-K kudlula u-0.03, amandla okuqina kanye nezinye izici zemishini ze-magnesium nazo zizoncipha kakhulu.
D. Kodwa lapho kokubili okuqukethwe kwe-Na kufinyelela ku-0.07% futhi okuqukethwe kwe-K kufinyelela ku-0.01%, amandla e-magnesium awanciphi, kodwa kuphela ipulasitiki yayo.
Ukumelana nokugqwala kwe-high-purity magnesium alloy kulingana nalokho kwe-aluminium
1. I-Matrix ye-Magnesium alloy isondelene ne-hexagonal lattice, i-magnesium iyasebenza kakhulu, futhi ifilimu ye-oxide ikhululekile, ngakho-ke ukukhishwa kwayo, ukuguqulwa kwepulasitiki kanye nenqubo yokulwa nokubola kuyinkimbinkimbi kune-aluminium alloy.
2. Ukumelana nokugqwala kwama-alloys e-magnesium ehlanzekile kulingana noma ngisho naphansi kunaleyo yama-alloys e-aluminium.Ngakho-ke, ukukhiqizwa kwezimboni ze-high-purity magnesium alloys kuyinkinga ephuthumayo okufanele ixazululwe ekusetshenzisweni kwenqwaba ye-magnesium alloys.
