Effect of deformation temperature on the behavior of individual dislocations in Al-3.3 at.% Mg solid-solution alloy single crystals was investigated by in situ observations of deformation in a high voltage electron microscope (HVEM). In the low temperature range (T≲0.32T_m; 290 K), the moving dislocations assumed some curvature and their motion was jerky. In the high temperature range (T≳0.60T_m; 550 K), deformation was homogeneous and homogeneous collective motion of dislocations was observed; every dislocation observed exhibited smooth and viscous motion under stress. On the other hand, in the intermediate temperature range (0.32T_m<T<0.60T_m) where P-L effect was expected, deformation was entirely inhomogeneous and slip bands were observed to run fast.
