Literature Survey on the Effect of Sonic and Ultrasonic Vibrations in Controlling Grain Size During Solidification of Steel Ingots and Weldments. Part 1 - Steel Ingots

Abstract

Steel ingots up to 12 in. in diameter and up to 5 ft. in length have been grain refined by the application of vibrational energy during solid ification. The cold-mold, consumable-electrode, arc-melting process and the electron-beam-melting process appear to be the most adaptable for ef ficient irradiation of an ingot. Most of the investigators have concluded that grain refine ment of weld metals by the application of vi brational energy, be it subsonic, sonic, or ultrasonic, holds great promise. The technique definitely has been shown to be effective. How ever, none of the investigations appear to have been extended to the application of vibrational treatment to industrial welding.
