Kumvetsetsa kwazinthu za magnesium alloy

(1) Mphamvu ndi kuuma kwa ma polycrystals oyera a magnesium sizokwera.Chifukwa chake, magnesiamu wangwiro sangathe kugwiritsidwa ntchito mwachindunji ngati zinthu zomangika.Magnesium yoyera nthawi zambiri imagwiritsidwa ntchito popanga ma aloyi a magnesium ndi ma aloyi ena.
(2) Magnesium alloy ndiye chinthu chobiriwira chaukadaulo chomwe chili ndi chitukuko komanso kuthekera kogwiritsa ntchito kwambiri m'zaka za zana la 21.

Magnesium amatha kupanga ma alloys ndi aluminium, mkuwa, zinki, zirconium, thorium ndi zitsulo zina.Poyerekeza ndi magnesium yoyera, alloy iyi imakhala ndi zida zamakina abwino kwambiri ndipo ndizinthu zamapangidwe abwino.Ngakhale ma alloys opangidwa ndi magnesium ali ndi zinthu zabwino zonse, magnesiamu ndi gawo lodzaza ndi hexagonal lattice, lomwe ndi lovuta kulikonza ndipo limakhala ndi ndalama zambiri pokonza.Chifukwa chake, kuchuluka kwaposachedwa kwa ma aloyi a magnesium ndi ochepa kwambiri kuposa aloyi a magnesium.Pali zinthu zambiri patebulo la periodic zomwe zimatha kupanga ma alloys okhala ndi magnesium.Magnesium ndi chitsulo, beryllium, potaziyamu, sodium, etc. sangathe kupanga ma alloys.Pakati pa ntchito magnesium aloyi kulimbikitsa zinthu, malinga ndi chikoka cha zinthu alloying pa katundu makina bayinare magnesium aloyi, zinthu alloying akhoza kugawidwa m'magulu atatu:
1. Zinthu zomwe zimapangitsa mphamvu ndi: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
2. Zinthu zomwe zimapangitsa kulimba ndi: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
3. Zinthu zomwe zimakulitsa kulimba popanda kusintha kwakukulu mu mphamvu: Cd, Ti, ndi Li.
4. Zinthu zomwe zimawonjezera mphamvu ndi kuchepetsa kulimba: Sn, Pd, Bi, Sb.
Mphamvu ya zinthu zonyansa mu magnesium
A. Zambiri mwa zonyansa zomwe zili mu magnesium zimakhala ndi zotsatira zoyipa pamakina a magnesium.
B. Pamene MgO idutsa 0.1%, mphamvu zamakina za magnesium zidzachepetsedwa.
Zomwe zili mu C ndi Na zikadutsa 0.01% kapena zomwe zili mu K zidutsa 0.03, mphamvu zamakina ndi zida zina zamakina a magnesium zidzachepetsedwa kwambiri.
D. Koma zonse za Na zikafika pa 0,07% ndipo K zomwe zili ndi 0.01%, mphamvu ya magnesium sichepa, koma pulasitiki yake yokha.
Kukana kwa dzimbiri kwa aloyi a magnesium alloy ndi ofanana ndi aluminiyumu
1. Magnesium alloy matrix imakhala yodzaza kwambiri ndi hexagonal lattice, magnesium imagwira ntchito kwambiri, ndipo filimu ya oxide imakhala yotayirira, kotero kuti kuponyera kwake, kusinthika kwa pulasitiki ndi anti-corrosion ndizovuta kwambiri kuposa aloyi ya aluminium.
2. Kukana kwa dzimbiri kwa ma aloyi oyeretsedwa kwambiri a magnesium ndi ofanana kapena ngakhale kutsika kuposa ma aloyi a aluminiyamu.Chifukwa chake, kupanga kwamafakitale kwa ma aloyi oyeretsedwa kwambiri a magnesium ndivuto lomwe likuyenera kuthetsedwa pakugwiritsa ntchito ma aloyi a magnesium.
