Mechanical behavior of MoSi2 and MoSi2 composites

MoSi2 is a key member of a new class of high-temperature structural silicide materials. Important features of the mechanical behavior of MoSi2 and MoSi2 composites are reviewed. The mechanical properties of Mosi2 single crystals, polycrystalline MoSi2, and MoSi2-based composites are discussed in association with properties such as elevated temperature deformation and low-temperature fracture toughness. Interrelationships between single crystal, polycrystal, and composite mechanical behavior are identified.
