Popis: In the present work was investigated the influence of solution treatment by 505°C, 515°C and 525°C±2°C with different holding times 2, 4, 8, 16 and 32 hours on microstructural elements of commercial AlSi9Cu3 cast alloy. During this heat treatment was observed the spheroidization of eutectic Si, gradual disintegration of iron rich intermetallic phases on base Al(FeMnMg)Si, shortening and thinning of Al5FeSi iron needles and the dissolving of Al-Al2Cu-Si intermetallic phase by temperature 525°C.
Učinak postupka topline obrade na morfologiju intermetalne faze ljevačke legure AlSi9Cu3. U članku je dano istraživanje utjecaja toplinskog otapanja na 505°C, 515°C i 525°C ± 2°C sa različitim vremenima držanja 2, 4, 8, 16 i 32 sata na mikrostrukturu komercijalne ljevačke legure AlSi9Cu3. Tijekom toplinske odredbe došlo je do sferoidizacije eutektičkog Si, postepenog raspada željeznih intermetalnih faza sa osnovom Al(FeMnMg)Si, skraćivanje i stanjivanje iglica faze Al5FeSi i otapanje intermetalne faze Al-Al2Cu-Si na temperaturi 525°C.
