Description

MoSi2 based composites possess significant potential as high temperature structural materials. The present investigation constitutes an initial study of the fabrication and properties of MoSi2/silicide alloys and SiC particle reinforced-MoSi2/silicide alloy matrix composites. Alloying disilicides (WSi2, NbSi2, TaSi2) and trisilicides (Mo5Si3, W5Si3, Nb5Si3, Ta5Si3, Ti5Si3) were examined. Results indicate that at the 50/50 mole % alloying level, MoSi2 formed solid solutions with the alloying disilicides. Reaction of the MoSi2TaSi2 alloy with SiC was observed. An initial assessment of 50/50 mole % disilicide alloy oxidation behavior suggests an oxidation resistance inferior to that of pure MoSi2
