English term or phrase: dislocations of opposite signs
The accumulation of dislocations is geometrically driven due to the
multiplication (e.g. Frank–Read sources and the nucleation of dislocation line
length at sources such as grain boundaries) and the trapping of dislocations
(sometimes referred to as debris). At its simplest level, the mechanism of dynamic
recovery involves the annihilation of dislocations of opposite signs in the crystal
which reduces the rate of increase of the dislocation density. At the saturation
limit of the flow stress, the accumulation and recovery terms balance. At ambient
temperatures it is often difficult to attain saturation of the flow stress.
