Abstract: The essence of the process of obtaining of the products by metallic powders aggregation is reprezented by the operations of the formation and sintering which determine the appearance of the, increase and stabilization of the contact surfaces, joined by the realization of the cohesion interatomic connexions among the particles. A body formed from the metal powders represents an unstable thermodynamic system, a state determined by the fineness of the powders, the roughness of the surface of the grains, their form, the degree of strain- hardness or cold-straining on the deformed areas, the damages of the multicrystalline networks on the surfaces of the grains (vacant locations, dislocations, etc).
