The influence of hot isostatic pressing (HIP) consolidation parameters on the mechanical properties of molybdenum disilicide (MoSi[sub 2]) and MoSi[sub 2] reinforced with ductile and brittle reinforcements was studied. MoSi[sub 2], MoSi[sub 2]-20 vol.% coarse and fine niobium powder and MoSi[sub 2]-20 vol.% silicon carbide whiskers consolidated by HIP at 1,200--1,400 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.
