A study of the effects of fast neutron irradiation on the mechanical properties of polycrystalline graphite is reported. Irradiation to a maximum dose of 1.14 x 10" n/cm2 at -50ยฐC increased the Young's modulus by 140%. The linearity of the compressive stress-strain curve increased and the hysteresis

kinematical theory of diffraction contrast has been applied to distinguish between vacancy and interstitial clusters. Interstitial clusters are the only ones which have been positively identified. The annealing of the clusters of defects has been studied in detail and activation energies derived. Th
Ahstraet-Large changes in the interlayer spacing of a graphite crystal can be obtained by the application of pressure or by fast neutron irradiation. In the latter case, it is well known that the thermal expansion coefficient parallel to the hexagonal axis ((I,) decreases substantially, while the ex
