Imikhiqizo ye-aluminium ne-aluminium isetshenziswa kabanzi ekukhiqizweni kwezimboni, futhi amasimu okusetshenziswa ahlukene anezidingo ezihluke kakhulu zesakhiwo esincane semikhiqizo ye-aluminium. Isibonelo, emkhakheni wezindiza, indinganiso ye-AMS 2482 ibeka izidingo ezicacile kakhulu zosayizi wezinhlamvu kanye nobukhulu bezinto zokwakha; kuma-radiator ezimoto, kunezidingo eziqinile ze-porosity yezingxenye ze-aluminium alloy. Ngakho-ke inhloso yokuhlaziywa kwe-metallographic ukunquma ukuthi umkhiqizo uyafaneleka yini ngokuhlaziya isakhiwo sawo esincane.
Ukuhlaziywa kwe-Metallographic kusebenzisa i-microscope ebonakalayo ukubona nokurekhodaizici zesakhiwo esincane se-aluminium kanye ne-aluminium alloys, njengosayizi wezinhlamvu, i-morphology, kanye nokufana, ukuze kutholakale amandla kanye ne-plasticity yezinto ezibonakalayo. Ingasetshenziswa futhi ukuhlaziya usayizi, ubuningi, uhlobo, kanye nezinye izakhiwo zezigaba zesibili. Ngesikhathi senqubo yokubuka, kunezidingo zokuqeda ubuso kanye nokuba bushelelezi kwento yokusebenza. Ngokuvamile, ukulungiswa kwesampula ye-metallographic kuyadingeka ngaphambi kokuhlolwa kokuhlaziywa kwe-metallographic ukuze kuqedwe umonakalo wobuso, kwembulwe isakhiwo sangempela se-metallographic sento yokusebenza, futhi kuqinisekiswe ukuthi idatha yokuhlaziywa elandelayo inembe kakhudlwana.
Izinyathelo zokulungiselela isampula zokuhlaziywa kwe-metallographic kwemikhiqizo ye-aluminium alloy ngokuvamile zihlanganisa ukusika, ukufaka, ukugaya nokupholisha i-metallographic, kanye nokugqwala. Umshini wokusika we-metallographic uyadingeka enkambisweni yokuthatha isampula, ohlonyiswe ngohlelo lokupholisa amanzi ukuvimbela ukuguquka komkhiqizo, ukusha komphezulu, kanye nomonakalo wesakhiwo ngesikhathi sokusika.
Ngenqubo yokufaka, ukufaka okushisayo noma ukufaka okubandayo kungakhethwa njengoba kudingeka; ukufaka okushisayo kusetshenziswa kakhulu emikhiqizweni ye-aluminium evamile. Ngesikhathi senqubo yokugaya nokupholisha, njengoba imikhiqizo ye-aluminium inobunzima obuphansi, ukusebenzisa i-sandpaper efanele kanye nendwangu yokupholisha kuhlanganiswe noketshezi lokupholisha kungasiza ekufezeni indawo engcono yesampula kuze kube yilapho kutholakala isibuko.
Okokugcina, ngenqubo yokugqwala, kunconywa ukusebenzisa isisombululo esithambile se-alkaline crispy ukuze kugwenywe ukulimaza isakhiwo esincane. Ngemva kokugqwala, isampula ingafakwa ngaphansi kwe-microscope ukuze kuhlaziywe i-metallographic.
