Some special features of the magnetic-pulse processing of the sintered powder materials are examined: loose of mechanical contact between tool and the billet, possibility of pressure setting with the determined distribution law along length and diameter of billet, capability of changing the structure and properties of material. Magnitude and duration of pulse electromagnetic field power impact to the powder billet is determined by electrical conductivity and plasticity of material, as well as by parameters of equipment (a generator of pulse currents) and tool (an inductor). Application of magnetic field concentrators offers the possibility of changing of geometric dimensions and properties of material. Processes of changing in macro and microstructure of surface, as well as an accuracy of the geometric dimensions of components are studied. Usage of magnetic-pulse deformation approach for obtaining the permanent joining of powder details with metallic and non-metallic elements, and items with the variable porosity is shown.
