The compressive creep of carbides having the composition U 0.79 Pu 0.21 C 1.02 and a sintered density of 11.8 g/cm 3 was studied at 1300°, 1400°, and 1500°C and stresses of 2000, 4000, and 6000 psi. The equation which best fitted the data was The dominant creep mechanism was probably grain‐boundary sliding. The hardness of monocarbides with various U/Pu ratios was measured from room temperature to 1200°C. Probable mechanisms of deformation are discussed.
