Metallographic-fractographic evaluation of the distribution of microdeformation processes in the volume of porous iron at the static tensile test demonstrates the influence of porosity on the concentration of deformation flows into the microvolume of connections. The degradation of deformation strengthened active volumes with the subsequent degradation of macrodeformation characteristics can occur in geometrically and structurally slightly developed connections.
