Dislocation distribution introduced into soft copper crystals by ultrasonic irradiation

摘要

Soft copper crystals in the form of specimens oriented for single glide in tensile tests were immersed in an ultrasonic cleaning bath. By etchhyphen;pitting lcub;111rcub; planes, it was found that irradiation had introduced dislocations which lay preferentially on the main glide plane. The dislocations produced more hardening on a plane which they intersected than on the plane on which they lay and the character of slip was different on the two planes.
