| Abstract: |
| Ni-Si/C composites have received significant attention in recent years, and they are considered by the automotive and aerospace industry as a replacement for conventional materials. Reactive melt infiltration process (RMI), whereby a melt is infiltrated into a porous preform by capillary force, is one of the most promising processes in fabricating composites with a high volume fraction of reinforcement. RMI can be made in this way with good near-net shape components. A two-dimensional numerical code have been developed using reaction-diffusion-formed Ni-Si/C as a model system for this process. Pore radii and reaction rates in order to investigate their effects on infiltration dynamics have been studied. And some aspects of the infiltration dynamics, highlighting the possible connections among the various processes have been reviewed as well. |
