✦ Synopsis
and exhibit no pronounced peaks. In contrast, the graphites having crystallites which possess good threedimensional order have a large, rather broad internal friction peak near room temperature, The height of this peak varies from 50 to 1 IO x IO4 depending upon crystallite size and the previous thermal and mechanical history of the sample. A relaxation in the dynamic modulus is associated with this peak. The peak is destroyed by anneahng above 450°K or by room temperature neutron irradiation. No evidence of a low temperature (about 50°K) peak was found. 39.
