The aim of this study is to investigate the effect of ultrasonic treatment on the microstructural and mechanical properties of A356 aluminum al-loy. Ultrasonic treatment was applied to 2 kg and 4 kg molten metals at different melting temperatures (700 oC, 720 oC and 740 oC) for different durations (0, 60, 180 and 300 seconds). Bifilm indices of the samples were also measured after all parameters were tested. The ultimate tensile strength (UTS) and elongation values were used to calculate the Quality Index (QI) of the samples. According to the results, the amount of liquid metal directly affects the the ultrasonic intensity that is produced during the treatment. Maximum UTS and elongation results were determined at 720 oC during 300 seconds for 4 kg casting. Minimum bifilm density val-ue was measured at the same ultrasonic temperature and time.
