Nuclear graphite grades, their manufacture, microstructure, and properties... 

The explanation for the shape of these dimensional change curves is related to the polycrystalline porous microstructure of nuclear graphite and the irradiation behavior of the graphite crystallites as follows [10] ...

FIGURE 2 The microstructure of the different regions in implanted polymers. Toward the mean range of the ions, dangling bonds and one-dimensional tracks, formed by nuclear stopping and secondary collisions, dominate. Toward the surface of the polymer, where electronic stopping dominates, the hard amorphous carbon and graphite structures exist.
