Effect of diffusion processes on sintering of metal powders

摘要: 1. The activation of the sintering process following addition other metals is linked with presence, generation, and interaction structural defects in particles, which facilitate diffusional creep metal. 2. The predominant direction fluxes between parent metal does not appear to be decisive importance process. 3. In by metallic additions, two physical factors are significance: thermodynamic instability structure course (presence defects) generation crystalline as a result diffusion processes. 4. The mechanism various additions affect sintering, however, may vary need always determined solely intensity mutual diffusion. The viscosity coefficient system can also lowered inhibition recovery reduction size mosaic blocks, happens presence nickel addition. 5. The activated exhibiting either full or limited solubility.
