Summary

Powder processing techniques have been used to prepare monolithic and composite samples in two silicide systems: Cr3Si and MoSi2. Two Mo-modified Cr3Si compounds were consolidated from prealloyed powders, as were composites reinforced either with Pt alloy fibers or Saphikon (alumina) whiskers. Composites of MoSi2, reinforced with SiC particles or particles plus whiskers, were consolidated by reactive sintering. Physical and mechanical properties of both systems, together with oxidation data for Cr3Si and its composites also are reported.
