Kev tsom xam ntawm magnesium alloy ingots feem ntau suav nrog kev ntsuam xyuas lawv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Nov yog cov ntsiab lus tseem ceeb los xav txog hauv kev tshuaj ntsuam:
1. Tshuaj muaj pes tsawg leeg
Elemental Analysis:Qhov no suav nrog kev ntsuas tus nqi ntawm cov khoom tseem ceeb alloying xws li:
Magnesium (Mg)
Aluminium (Al)
Zinc (Zn)
Manganese (Mn)
Silicon (Si)
Copper (Cu)
Rare earth elements (yog muaj)
Qauv:Sib piv cov qauv kev lag luam (piv txwv li, ASTM, ISO) lossis cov khoom tshwj xeeb tshwj xeeb.
2. Mechanical Properties
Tensile zog:Ntsuas qhov siab tshaj plaws kev ntxhov siab uas cov alloy tuaj yeem tiv taus thaum raug ncab.
Yield zog:Qhov kev ntxhov siab uas cov khoom pib deform plastically.
Elongation:Qhov no qhia txog ductility thiab ntsuas raws li feem pua ntawm elongation ua ntej so.
Hardness:Feem ntau raug soj ntsuam siv txoj hauv kev xws li Brinell, Rockwell, lossis Vickers.
Fatigue Strength:Txiav txim siab cov khoom muaj peev xwm tiv taus kev thauj khoom cyclic.
3. Microstructural Analysis
Grain Structure:Kev txheeb xyuas cov qoob loo loj thiab morphology siv optical microscopy lossis scanning electron microscopy (SEM).
Phase Identification:Txheeb xyuas ntau theem tam sim no nyob rau hauv cov hlau siv X-ray diffraction (XRD).
Inclusions thiab Defects:Tshawb xyuas cov impurities, suav nrog, lossis porosity uas yuav cuam tshuam rau cov khoom siv.
4. Cov yam ntxwv ua haujlwm
Corrosion Resistance:Ntsuas seb cov hlau ua tau zoo li cas hauv qhov chaw corrosive, nrog rau cov kev sim xws li cov tshuaj tsuag ntsev.
Thermal Properties:Ntsuas thermal conductivity thiab nthuav tus cwj pwm yog tias tsim nyog.
5. Txoj Kev Xeem
Spectrometry:Cov txuj ci xws li Optical Emission Spectroscopy (OES) rau kev tsom xam.
Mechanical Testing:Siv cov txheej txheem txheem (xws li ASTM E8 rau kev ntsuas tensile).
Kev kuaj tsis yog kev puas tsuaj (NDT):Txhawm rau txheeb xyuas qhov tsis xws luag yam tsis muaj kev puas tsuaj rau cov ingots.
6. Ua Keeb Kwm
Cov ntaub ntawv hais txog cov txheej txheem tsim khoom, cov txheej txheem casting, thiab cov kev kho tom qab ua tiav, xws li kev kho cua sov lossis kev siv alloying, tuaj yeem cuam tshuam rau kev nkag siab txog cov khoom ntawm cov khoom.
