Abstract
In this paper, the possibility of synthesis and in-situ densification of MoSi₂ alloys using the thermal explosion mode of Self-propagating High-temperature Synthesis was demonstrated. Mo-Si powder mixture synthesized by SHS process under 35MPa yielded porous MoSi₂ product. Proper combinations of the processing variables including the applied pressure, diluent contents, and alloying elements(Al and Ti) yielded the product density up to 99% theoretical density.
