| Abstract Scope |
Ultrasound metrology can enable real-time imaging and velocity measurement in a metal melt during its solidification, which could allow us to predict and control casting product quality. In a prior study, we found that the specular reflection of sound waves is the working principle of solidification-front tracking. However, the source and mechanism of bulk echoes in metal melts are still unclear. In this work, we focus on investigating the relationship between bulk echoes and oxide inclusions in the metal melt. Using novel experimental methods, we can observe the movement of oxide inclusions in the metal melt. By analyzing the echo strength, we explore the mode of acoustic scattering based on particle type and size in the melt. We also study the possibility of the existence of ultrasound induced cavitation under our experimental conditions. The experimental results presented here provide an innovative insight into the mechanisms of ultrasound in metal melt. |
