(1) Simba uye kuoma kweiyo yakachena magnesium polycrystals haina kukwirira.Naizvozvo, yakachena magnesium haigone kushandiswa zvakananga sechinhu chechimiro.Magnesium yakachena inowanzoshandiswa kugadzira magnesium alloys uye mamwe alloys.
(2) Magnesium alloy ndiyo yakasvibira einjiniya zvinhu zvine budiriro yakanyanya uye inogona kushandiswa muzana remakore rechi21.
Magnesium inogona kuumba alloys nealuminium, mhangura, zingi, zirconium, thorium nedzimwe simbi.Kuenzaniswa neiyo yakachena magnesium, iyi alloy ine zvirinani zvemuchina uye yakanaka yezvimiro zvinhu.Kunyangwe yakagadzirwa magnesium alloys ine yakanaka yakazara zvivakwa, magnesium iri padhuze-yakazara hexagonal lattice, iyo yakaoma kurongedza mupurasitiki uye ine yakakwira mitengo yekugadzirisa.Naizvozvo, huwandu hwazvino hweakagadzirwa magnesium alloys idiki zvakanyanya pane iyo yakakandwa magnesium alloys.Kune akawanda ezvimiro muiyo periodic tafura iyo inogona kugadzira alloys ane magnesium.Magnesium uye iron, beryllium, potassium, sodium, nezvimwewo haigoni kuumba alloys.Pakati pezvakaiswa magnesium alloy kusimbisa zvinhu, zvinoenderana nesimba realloying zvinhu pane mechaniki zvivakwa zvebinary magnesium alloys, alloying zvinhu zvinogona kukamurwa muzvikamu zvitatu:
1. Zvinhu zvinovandudza simba ndezvi: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
2. Zvinhu zvinovandudza kuoma ndezvi: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
3. Zvinhu zvinowedzera kuoma pasina shanduko yakawanda musimba: Cd, Ti, uye Li.
4. Zvinhu zvinowedzera simba uye kuderedza kusimba: Sn, Pd, Bi, Sb.
Kufurira kwezvinhu zvisina kuchena mu magnesium
A. Zvizhinji zvetsvina iri mumagnesium ine zvakaipa zvinokonzeresa pamichina ye magnesium.
B. Apo MgO inopfuura 0.1%, iyo mechanical properties ye magnesium ichaderedzwa.
Kana zvirimo zveC neNa zvichidarika 0.01% kana zviri muK zvinopfuura 0.03, simba rekusimba uye mamwe ma mechanic properties ye magnesium zvakare ichaderedzwa zvakanyanya.
D. Asi apo zvose zviri zviviri zveNa zvinosvika 0.07% uye K zvinyorwa zvinosvika 0.01%, simba re magnesium harina kuderera, asi plastiki yayo chete.
Iyo corrosion resistance ye-high-purity magnesium alloy yakaenzana neyealuminium
1. Magnesium alloy matrix iri pedyo-packed hexagonal lattice, magnesium inonyanya kushanda, uye oxide firimu yakasununguka, saka kukanda kwayo, plastiki deformation uye anti-corrosion process yakanyanya kuoma kupfuura aluminium alloy.
2. Kudzivirirwa kwekuora kwepamusoro-kuchena magnesium alloys yakaenzana kana kunyange kuderera kupfuura iyo yealuminium alloys.Naizvozvo, kugadzirwa kwemaindasitiri kweyakanyanya-kuchena magnesium alloys idambudziko rekukurumidzira kuti rigadziriswe mukuwanda kwekushandiswa kwema magnesium alloys.
