  • 摘要: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). The basic parameters of the sintering are : the temperature and the sintering duration, the procedure of heating and the environment (the atmosphere) where the sintering is taking place.
