Microstructure refinement of Sn-Sb Peritectic alloy by power ultrasonic

Sn-Sb peritectic alloy was treated with 400 W, 600 W and 800 W ultrasonic, respectively, to study the effect of power ultrasonic on solidification microstructure. Results show that power ultrasonic can refine alpha phase and beta phase of the alloy, as well as eliminate gravitational segregation. Mo...

Description
Summary:Sn-Sb peritectic alloy was treated with 400 W, 600 W and 800 W ultrasonic, respectively, to study the effect of power ultrasonic on solidification microstructure. Results show that power ultrasonic can refine alpha phase and beta phase of the alloy, as well as eliminate gravitational segregation. Moreover, 600 W ultrasonic demonstrated the best refining effect, not only homogenous and fine solidification microstructure can be obtained, the cubical beta phase crystals can also be spheroidized.
