The article contains a description of the technology production of cylindrical samples sintered of powder by using input material conditions of a trial deformation. The results of changes in porosity before and after the deformation are analyzed. Analysis of changes in the internal structure of the sinters were based on maps prepared porosity distribution for the states of deformation, carried out in conditions of freedom compression cold. Currently we are looking for effective methods of processing sintered towards obtaining the highest possible density of the homogeneous character the distribution volume. In the present study we analyzed the impact of the classical way of deformation sintered to changes in the internal structure due to the evolution of porosity. The study used an original approach to the assessment of porosity in the local areas, was conducted quantitative metallographic share porosity, based on the results prepared model the spatial distribution maps porosity.
