✦ Synopsis

Tensile creep tests with durations of 90-120 min were performed on several different types of graphite over the temperature range of 2300 to 2900°C. For ATJ graphite, the creep rate was found to vary with the fourth power of the stress on specimens oriented both "with-the-grain" and "against-the-grain".

An activation energy of 124 kcal/mole was determined from the temperature dependence of the creep rate. This activation energy was found to be the same for both grain orientations and for all of the graphites which were tested. The influence on the creep of anisotropy,grain orientation, density, and the relative proportions of filler and binder coke in the graphite will be discussed.
