The stability of the dislocation sub-systems of face-centered cubic single crystals which had been deformed under dynamic conditions was investigated. It was shown that, depending upon the deformation conditions, the system could have one or two steady states. When the system had one trivial steady state, it could be stable or unstable. Under some conditions, a second unstable point appeared.
