The subject of this study has been an investigation of the homogenization temperature
effect on the microstructure of Al-Mg-Si alloy containing low-melting point Pb and Bi
elements. The results of the characterization show that homogenization at temperatures
lower than 500 °C requires extraordinary long in order to initiate ß-AlFeSi -> α-AlFe(Mn)Si
transformation, necessary for good extrdability of the alloy ransformation, necessary for
good extrudability of the alloy. In addition, precipitation of ß-Mg2Si phase takes place,
decreasing the alloy's aging potential during the further processing. High-temperature
homogenization not only results in complete ß-AlFeSi -> α-AlFe(Mn)Si transformation and
dissolution of ß-Mg2Si phase but expected Pb and Bi escape to the specimen surface does
not occur.
Predmet ovog rada je bilo ispitivanje i karakterizacija uslova homogenizacionog žarenja na
mikrostruktu Al-Mg-Si legure legirane nisko-topivim metalima Pb i Bi. Rezultati pokazuju da
homogenizacija na temperaturama nižim od 500 °C zahteva izuzetno duga vremena žarenja
da bi došlo do ß-AlFeSi -> α-AlFe(Mn)Si transformacije, neophodne za sposobnost legure za
presovanje. Dodatno, dolazi do izdvajanja ß-Mg2Si faze, čime se smanjuje sposobnost legure
za starenje u daljoj preradi. Visoko-temperaturna homogenizacija ne samo da rezultuje u
potpunoj ß-AlFeSi -> α-AlFe(Mn)Si transformaciji i rastvaranju ß-Mg2Si faze, već i ne dolazi
do očekivanog gubitka Pb i Bi usled izdvajanja na površini uzoraka.
