Abstract : The creep properties of thorium have been determined at 200 F, 400 F, and 600 F under constant load conditions. The deformation of thorium by creep at 400 F and 600 F appears to be modified by an aging process which results in a lower creep rate at 400 F than the same stress would produce at 200 F. From the observed results, design considerations for the use of thorium under cyclic load conditions in the temperature range from 200 F to 600 F should be based largely on fatigue strength, rather than on creep strength.
