The mechanical relaxation modes for paired point defects in h.c.p. structures have been calculated by use of group theory methods. The corresponding point group symmetry is D,, for interstitial-interstitial pairs and D,, for substitutional-interstitial or substitutional-substitutional and vacancy-va
Stress relaxation experiments in monotonic loading have been performed on niobium and z-iron of two purity levels. The stress-strain rate relationship obtained at constant structures suggests that these metals exhibit the behavior of mechanical equation of state in the absence of discontinuous flow.
