摘要：

For lamellar aggregates, a small size scale is attained where flow in a ductile layer occurs by the motion of single dislocations rather than dislocation arrays. Analysis of such a case indicates that the flow stress should follow an Orowan-type relation accompanied by rapid effective work hardening. Consequences for flow instability and fracture are considered.
