Effect of Ultrasonic Power on the Microstructure and Hardness of Commercially Pure Aluminum

Article Preview

Abstract:

Molten, commercially pure aluminum has been treated ultrasonically with differing input power. The results show that the ultrasonic power can significantly refine the microstructure of the aluminium and increase the hardness of the samples. A mathematical model developed in this paper can predict the effect of the ultrasonic power on the grain size of the pure aluminium well.
