Abstract
The influence of 20kHz ultrasonic energy on metallurgical properties of cold rolled sheet steel specimens during annealing was investigated. Acoustic energy caused an acceleration in grain growth rate. Annealing texture was also modified by ultrasound as well as the grain growth was enhanced. As a result of these effects, the ductility of the sheet steel for press forming was increased appreciably, and the drawability hence much improved. Efficiency of over-aging treatment in a continuous annealing process of sheet steel was nearly doubled by ultrasonic irradiation during over-aging.
