Abstract
Submicrocrystalline nickel produced by ultrasonic impact treatment was studied using scanning tunnel and optical microscopy. The size and grain boundary energy distributions were obtained depending on the distance from surface. It was found that regardless of processing mode ultrasonic impact treatment led to refinement of the thin surface layer comparable with initial grain size. Analysis of cumulative distribution functions for relative boundary energy allows us to study energy redistribution under treatment and qualitatively estimate low-angle and high-angle boundaries contributions.
