| Abstract Scope |
High-temperature materials are critical for the continued development of applications such as advanced gas turbines and nuclear reactors. However, the high melting temperatures of these material systems make the fabrication of near-net-shape components challenging due to the substantial energy required for conventional processing methods. Self-Propagating High-Temperature Synthesis (SHS) offers an alternative route that leverages the exothermic nature of intermetallic and ceramic formation, providing a rapid, energy-efficient fabrication method. This investigation examines the relationship between thermal response, liquid-phase formation, and in-situ pressure application on the densification during SHS processing, with the goal of enabling dense near-net-shape component fabrication. NiAl intermetallic was selected as a model system. Experimental temperature measurements were compared to computational values obtained using CALPHAD. |
