| Summary: | The present invention relates to intermetallic materials based on MoSi
, intermetallic matrix composites and methods of making the same. More particularly, the invention is directed to a MoSi
based material having an engineered micro-structure provided through the use of in-situ reinforcement whiskers.
A MoSipest resistant material includes in-situ grown -SiNwhiskers. In addition to excellent pest resistance, the material provides a lower coefficient of thermal expansion for better match with continuous reinforcing fibers such as SiC fibers. A two stage heating and pressing production technique enables lower temperature processing with substantially full densification. |
