摘要：

Cyclic strain experiments have been conducted to determine the widening behaviour of cleared channels in neutron irradiated copper as a function of applied reverse strain per cycle. It is found that widening occurs during only a portion of each cycle. A model is developed which explains this and other experimental observations in terms of the effect of stress fields surrounding clusters of dislocation dipoles which are found in the channels. © 1969.
