%X Containerless treatment of Bi-58.5at%Ga hypermonotectic alloy is successfully performed with acous-tic levitation technique. Under acoustic levitation condition,the second phase (Ga) distributes almost homogeneously in solidification sample,opposite to macrosegregation in solidification sample under conventional condition. Stokes motion of the second liquid droplet (Ga) is significantly restrained un-der acoustic levitation condition. The analyses indicate that the melt vibration in the gravity direction forced by acoustic field can induce steady flow around the second liquid droplet,which influences droplet shape during its moving upward and consequently restrains Stokes motion velocity of the second liquid droplet.
