(1) Matla le boima ba li-polycrystals tse hloekileng tsa magnesium ha li phahame.Ka hona, magnesium e hloekileng e ke ke ea sebelisoa ka kotloloho e le thepa ea sebopeho.Magnesium e hloekileng hangata e sebelisoa ho lokisa li-alloys tsa magnesium le lisebelisoa tse ling.
(2) Magnesium alloy ke thepa ea boenjiniere e tala e nang le nts'etsopele le bokhoni ba ts'ebeliso e kholo lekholong la bo21 la lilemo.
Magnesium e ka etsa li-alloys ka aluminium, koporo, zinki, zirconium, thorium le litšepe tse ling.Ha ho bapisoa le magnesium e hloekileng, alloy ena e na le thepa e ntle ea mochini ebile ke thepa e ntle ea sebopeho.Le hoja li-alloys tsa magnesium tse entsoeng li na le thepa e ntle e pharaletseng, magnesium ke lesela le haufi le hexagonal, leo ho leng thata ho le sebetsa ka polasetiki 'me le na le litšenyehelo tse phahameng tsa ho sebetsa.Ka hona, palo ea hona joale ea li-alloys tse entsoeng ka magnesium e nyane haholo ho feta ea li-alloys tsa magnesium.Ho na le likarolo tse ngata tafoleng ea periodic tse ka etsang li-alloys tse nang le magnesium.Magnesium le tšepe, beryllium, potasiamo, sodium, joalo-joalo ha li khone ho etsa li-alloys.Har'a lisebelisoa tse matlafatsang tsa magnesium alloy, ho latela tšusumetso ea likarolo tsa alloy ho thepa ea mochini oa li-alloys tsa magnesium, likarolo tsa alloy li ka aroloa ka mekhahlelo e meraro:
1. Lintho tse ntlafatsang matla ke: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
2. Lintho tse ntlafatsang ho tiea ke: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
3. Lintho tse matlafatsang ho tiea ntle le phetoho e ngata ea matla: Cd, Ti, le Li.
4. Lintho tse eketsang matla haholo le ho fokotsa ho tiea: Sn, Pd, Bi, Sb.
Tšusumetso ea lintho tse sa hloekang ka magnesium
A. Boholo ba litšila tse ka har'a magnesium li na le litlamorao tse mpe mekhoeng ea magnesium.
B. Ha MgO e feta 0.1%, thepa ea mechine ea magnesium e tla fokotseha.
Ha litaba tsa C le Na li feta 0.01% kapa likahare tsa K li feta 0.03, matla a tsitsipano le lisebelisoa tse ling tsa mochine oa magnesium le tsona li tla fokotseha haholo.
D. Empa ha litaba tsa Na ka bobeli li fihla ho 0,07% 'me litaba tsa K li fihla ho 0,01%, matla a magnesium ha a fokotsehe, empa ke polasetiki ea eona feela.
Khanyetso ea kutu ea alloy ea magnesium e phahameng e lekana le ea aluminium
1. Magnesium alloy matrix e haufi-ufi-packed hexagonal lattice, magnesium e sebetsa haholoanyane, 'me filimi ea oxide e hlephile, kahoo ho lahla ha eona, deformation ea polasetiki le anti-corrosion process e rarahane ho feta motsoako oa aluminium.
2. Ho hanyetsa ho bola ha li-alloys tsa magnesium tse phahameng ho lekana kapa ho fokotseha ho feta li-alloys tsa aluminium.Ka hona, tlhahiso ea indasteri ea li-alloys tsa magnesium tse hloekileng haholo ke bothata bo potlakileng bo lokelang ho rarolloa ts'ebelisong e kholo ea li-alloys tsa magnesium.
