Abstract

Minimum creep rates of nickel samples were measured in the stress region of 2.5×107 to 2.8×109 dyne per sq cm and the temperature region of 400° to 1100°C. The creep rate seems to be proportional to (stress)4.6 at stresses below 7×108 dyne per sq cm. The activation energy of creep is approximately 65,000 cal per mol.
