โฆ Synopsis
The Young's modulus of pyrolytic graphite having varying degrees of preferred orientation, has been measured using the flexural vibration technique. The results are compared with Young's Modulus values predicted using single crystal elastic constants. The effect of neutron irradiation on the material in its various stages of crystal alignment lends strong support to the applicability of the uniform stress model to graphite.

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 the
