Effect of low-intensity ultrasound on grain refinement and heterogeneous nucleation mechanism of 2219 Al alloy

The ultrasonic cavitation and acoustic streaming have long been regarded as the dominant mechanisms for refining the solidification microstructure of Aluminum (Al) alloys. This work investigated the effects of low-intensity ultrasound on the solidification microstructure of 2219 Al alloy by setting...
