  • Kev nkag siab zoo ntawm magnesium alloy cov ntaub ntawv

    (1) Lub zog thiab hardness ntawm ntshiab magnesium polycrystals tsis siab.Yog li ntawd, ntshiab magnesium tsis tuaj yeem siv ncaj qha los ua cov khoom siv.Ntshiab magnesium feem ntau yog siv los npaj magnesium alloys thiab lwm yam alloys.
    (2) Magnesium alloy yog cov khoom siv hluav taws xob ntsuab nrog kev txhim kho thiab kev siv peev xwm tshaj plaws hauv lub xyoo pua 21st.

    Magnesium tuaj yeem tsim cov alloys nrog txhuas, tooj liab, zinc, zirconium, thorium thiab lwm yam hlau.Piv nrog cov magnesium ntshiab, cov hlau no muaj cov khoom siv zoo dua qub thiab yog cov khoom siv zoo.Txawm hais tias wrought magnesium alloys muaj cov khoom zoo, magnesium yog ib qho ze-packed hexagonal lattice, uas nyuaj rau plastically txheej txheem thiab muaj cov nqi ua haujlwm siab.Yog li ntawd, tam sim no tus nqi ntawm wrought magnesium alloys yog tsawg dua li ntawm cam khwb cia magnesium alloys.Muaj ntau ntau cov ntsiab lus nyob rau hauv lub sij hawm lub rooj uas tuaj yeem tsim cov alloys nrog magnesium.Magnesium thiab hlau, beryllium, potassium, sodium, thiab lwm yam tsis tuaj yeem tsim cov alloys.Ntawm cov khoom siv magnesium alloy ntxiv dag zog rau cov ntsiab lus, raws li kev cuam tshuam ntawm cov ntsiab lus alloying ntawm cov khoom siv ntawm binary magnesium alloys, cov ntsiab lus alloying tuaj yeem muab faib ua peb pawg:
    1. Cov ntsiab lus uas txhim kho lub zog yog: Al, Zn, Ag, Ce, Ga, Ni, Cu, Th.
    2. Cov ntsiab lus uas txhim kho toughness yog: Th, Ga, Zn, Ag, Ce, Ca, Al, Ni, Cu.
    3. Cov ntsiab lus uas txhim khu lub zog tsis muaj kev hloov pauv ntau lub zog: Cd, Ti, thiab Li.
    4. Cov ntsiab lus uas ua rau kom muaj zog thiab txo qhov hnyav: Sn, Pd, Bi, Sb.

    Kev cuam tshuam ntawm impurity ntsiab hauv magnesium
    A. Feem ntau ntawm cov impurities muaj nyob rau hauv magnesium muaj kev phiv rau cov neeg kho tshuab zog ntawm magnesium.
    B. Thaum MgO tshaj 0.1%, cov khoom siv ntawm magnesium yuav raug txo.
    Thaum cov ntsiab lus ntawm C thiab Na ntau dua 0.01% lossis cov ntsiab lus ntawm K ntau tshaj 0.03, lub zog tensile thiab lwm yam khoom siv ntawm magnesium kuj yuav txo qis heev.
    D. Tab sis thaum ob qho tib si Na ntsiab lus nce mus txog 0.07% thiab K cov ntsiab lus nce mus txog 0.01%, lub zog ntawm magnesium tsis txo qis, tab sis tsuas yog nws cov plasticity.

    Lub corrosion kuj ntawm high-purity magnesium alloy yog sib npaug rau cov txhuas
    1. Magnesium alloy matrix yog kaw-packed hexagonal lattice, magnesium yog active, thiab oxide zaj duab xis yog xoob, yog li nws casting, yas deformation thiab anti-corrosion txheej txheem yog ntau nyuaj tshaj li txhuas alloy.
    2. Lub corrosion kuj ntawm high-purity magnesium alloys yog sib npaug los yog txawm qis dua li ntawm aluminium alloys.Yog li ntawd, kev tsim khoom ntawm high-purity magnesium alloys yog qhov teeb meem ceev uas yuav tsum tau daws nyob rau hauv daim ntawv thov loj ntawm magnesium alloys.
