Investigation of "shock-induced" and "shock-assisted" chemical reactions in Mo + 2Si powder mixtures

Metallurgical and Materials Transactions | January 1, 2003| | Copyright

Chemical reactions occurring in Mo + 2Si powder mixtures under "shock-induced" (during the highpressure shock state) and "shock-assisted" (due to bulk temperature increases subsequent to unloading from the shock state) conditions were investigated using shock recovery experiments performed under a range of loading conditions. Cylindrical implosion geometry experiments showed fully reacted mixed-phase eutectic microstructure (MoSi^sub 2^ and Mo^sub 5^Si^sub 3^) in axial regions and a partially reacted region (containing MoSi^sub 2^ spherules surrounding molybdenum particles in melted and ...
