Abstract

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 MoSi₂Al₂O₃. 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.
