TiC particulates reinforced Fe-based composites have been fabricated using ferrotitanium and carbon black powders with the combination of in situ and spark plasma sintering (SPS) technique. The sintering and densification behaviors were investigated. The results show that when the composite was sintered at 1150°C for 5min, the maximum relative density and hardness are 99.2% and 83.2 HRA, respectively...
In this paper, the genetic algorithms were used to realize optimization of the chemical vapor infiltration (CVI) process for manufacturing carbon-carbon composites for the first time. The density homogeneity, bulk density and infiltration time were selected as the optimizing objectives, and the density homogeneity was taken as the main optimizing objective. By combining selection, crossover and mutation...
