In development work on processes for the production of sintered parts for structural applications particular attention is given to the mechanism of porosity variation. The densification of porous materials has been the subject of theoretical investigations based on one of the more promising numerical methods of calculation -the finite-elements method [i, 2]. This method, however, in common with other theoretical methods of investigation of the densification and shape variation process, is complex and labor-consuming and cannot therefore always be used. In view of this, in practice recourse is often had to simpler, experimental techniques for studying processes of deformation of materials, which also enable the physicomechanical properties of resultant parts to be assessed. They include microstructural analysis and hardness testing. These methods can be employed for studying processes of plastic deformation of blanks of both simple and complex configurations. Apart from this, on the basis of experimental investigations it is possible to verify results of earlier theoretical investigations.
