Summary

Combustion synthesis can be an economical method for the production of advanced materials. One of its limitations is the large amount of porosity retained in the final products. Performing combustion synthesis under pressure takes advantage of the high temperatures produced by the exothermic reactions to aid in densifying the material. The results of simultaneous combustion and densification of SiC and TiC are presented. The effects of mechanical loading before and after the reaction were compared. Loading prior to combustion was found to increase the final density. The fabrication of TiC-SiC composites by reaction of Ti, C, and SiC by combustion under load was found to significantly increase the density compared to that of hot-pressed, pre-reacted materials.
