Various viscous behaviors different from the creep behavior are generally observed in polycrystalline metals under the particular loading process even below their recrystallization temperature. In order to describe such behaviors a concept of "free dislocation" which does not contribute instantaneously to produce the plastic strain, is added to the random barriers theoy considering a dynamic effect of dislocation. It has shown that a deficient and excess of these frcc dislocations brings forth the viscous plastic deformation under the transient loading process. This presented model is found to be applicable for describing the various viscous behaviors experimentally obtained on the stainless steel under some rate dependent loading conditions.
