THE DISLOCATION DISTRIBUTION IN FACE CENTERED CUBIC METALS AFTER FATIGUE,

Abstract

The dislocation distribution in fatigued metals was studied by transmission electron microscopy in aluminum, copper and 70-30 brass. In aluminum and copper where cross-slip is easy, the dislocations are arranged in tangles and clusters of elongated dislocation loops. In 70-30 brass, the dislocations are uniformly distributed throughout the grains, with a large amount of dislocation debris (small loops, short jogged dislocation segments) and long rows of dislocation dipoles.
