Abstract
The growth of zinc single crystals (purity 99.993%) in sonic and ultrasonic fields of 0.1 to 50 watts/cm2 was studied at frequencies within the range of 100 to 25 000 cycles per second using a modified Czochralski technique. Changes in surface roughness, crystallographic orientation and critical shear stress appeared, depending upon the intensity of the applied sound field. An attempt is made to discuss the results on the basis of concepts that involve the influence of sound on the conditions of vacancy supersaturation during cooling of the crystal, and the formation of dislocation networks during homogenization behind the solid-liquid interface.Keywords
