The effect of ultrasonic vibration on the microstructure, elimination of casting defects and distribution of alloyed elements at macro-scale during solidification of 35CrMo steel has been investigated. Results show that ultrasonic treatment has a significant effect on the grain refinement, especially the fragmentation of the secondary dendritic arms of the studied steel. Density of the casting defects decreases and the alloyed elements are seen more even distribution at macro-scale with the introduction of ultrasonic vibration. Meanwhile, the ultrasonic vibration works more efficiently in the longitudinal direction than in the radial, and its efficiency declines with the distance from the radiator increasing.
