摘要
We discuss the rheological properties of the suspension of gamma -Fe//2O//3 in silicone oil at the stress level near the true yield stress by the aid of creep experiments. In the creep experiment at various magnitudes of shear stress measured immediately after cessation of shear flow, the density of structural networks seems to increase depending on the applied force at initial time region, however, with increasing time, the irreversible flow becomes dominant in their creep behavior. An elastic behavior of interparticle network structure can be presumed by a creep recovery. The elastic modulus estimated from the relationship between the applying stress and the recoverable strain is about 1100 dyne/cm**2.
