Sažetak

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.
