摘要：
The influence of hot isostatic pressing (HIP) consolidation parameters on the mechanical properties of molybdenum disilicide (MoSi2) and MoSi2 reinforced with ductile and brittle reinforcements was studied. MoSi2, MoSi2-20 vol.% coarse and fine niobium powder and MoSi2-20 vol.% silicon carbide whiskers consolidated by HIP at 1200-1400-degrees-C, 207 MPa, for 1 and 4 h were tested in compression for elevated temperature strength and creep resistance. Single-edge-notched specimens of the three materials were tested in a three-point bend configuration for fracture toughness. Mechanical properties were related with consolidation parameters and post-HIP microstructures.
