ENGINEERING PROGRESS REPORT ON INVESTIGATION OF THE BASIC MECHANISM OF METAL FATIGUE.

Abstract

Copper single crystals of orientations <100>, <110>, and <111> were deformed in tension at room temperature. The attenuation of a 10 mc longitudinal wave propagating in each crystal increased continuously during deformation. The change of attenuation decreases with increasing number of equally favored slip systems. After unloading, each of the crystals exhibited attenuation recovery. (Author)
