Zusammenfassung:The same experiment was conducted with molten magnesium (purity: 99.8%). The temperature of the magnesium was 680°C. Figure 3b shows typical signals obtained using the buffer rods having flat probing ends with the pitch-catch mode. The backscattered ultrasonic signals from inclusions were observed as they were in the molten aluminum experiment. However, it should be noted that the scattered signals were observed without adding any inclusions to the molten magnesium.
