At temperatures of about 0.3 Tm, the mobility of dislocations out of thermo- dynamical equilibrium is controlled by the agglomerates of defects reducing their mobility. Annealing at T > 973 K is needed for dissolving the agglomerates, allowing the dislocations start their movement. In this work we have related the results of mechanical spectroscopy, transmission electron microscopy, electrical resistivity, dierential thermal analysis and small angle neutron scattering, as obtained in deformed and neutron irradiated Mo single crystals.Tm, the mobility of dislocations out of thermo- dynamical equilibrium is controlled by the agglomerates of defects reducing their mobility.
