摘要：

Several techniques have been employed to consolidate MoSi2 composites reinforced with either Al2O3 or niobium. Powder injection molding was used to prepare MoSi2 with aligned short FP Al2O3 fibers. Plasma spray was used to produce lamellar MoSi2-Al2O3. Niobium particles, random short fibers and continuous fibers were incorporated into MoSi2 by hot isostatic pressing. Microstructures and mechanical properties of the various composites are reported. Significant microscopic toughening was obtained with continuous niobium fibers, but at the expense of creep resistance.
