Mishra, Suman K and Pathak, L C (2002) Self-Propagating High-Temperature Synthesis(SHS) of Advanced High Temperature Materials. In: Proceedings of the Indo-Malaysian Joint Workshop(WAM-2002), 12-13 March, 2002, National Metallurgical Laboratory, Jamshedpur.
Over the last few years, our research group at National Metallurgical Laboratory Jamshedpur had contributed significantly on the fabrication of various advanced high temperature materials monolithic and composites namely ZrB2, TiC, ZrB;-A1zO 3 and AlzO3-SiC by self-propagating hightemperature synthesis (SHS) technique. In this paper, the SHS processes developed at National Metallurgical Laboratory, Jamshedpur are reviewed Ultra fine ZrB2, TiC, TiC-Ni powder were prepared. New in-situ composites in the ZrBz-A1203, Alz03-SiC,., TiC-Ni were prepared by the SHS techniques.The studies were focused on the SHS processing, mechanism of phase formation, microstructure evaluation, sintering of SHS produced powder and their property eval-uation. A new combustion synthesis technique using a rapid heating self-propagating high temperature synthesis (RH-SHS) was made for the fabrication of in-situ AlzO3-SiCu, composite. Process for the in-situ preparation of 96% dense ZrBz-Al103 by the SHS was developed.
