Panin, V. Polyakov, G. Syrov, A. Fadeev] An experimental study was made of the structure of deformed porous iron with a porosity P ranging from 4 to 40% within the range of strains ε up to fracture. Measurements are made of grain-boundary slip and rotations of structural elements and their individual contributions to the total strain as a function of P and ε. It is established that there is a change in the dominant mechanisms of plastic deformation with an increase in porosity, this change being connected with a change in the topological characteristics of the system and corresponding to the transition from intergranular slip to a group of mechanisms that ensures movement of the grains as a whole. The established laws are analyzed on the basis of the concept of structural levels of deformation. Plenum Publishing Corporation, 1996 Panin V.
