Abstract
The fine structure of carbon fibers synthesized under various technological conditions is studied. It is found that the material of the fibers is heterogeneous and its component composition is determined by thermomechanical treatment conditions and the presence of a boron addition and depends on the angle of coherent-domain orientation φ with respect to the fiber axis. The detected dependences of the component composition of the fibers on the heat-treatment temperature and time and the angle of coherent-domain orientation with respect to the fiber axis suggest that the transition of the carbon material of the fibers into a more equilibrium state is likely to proceed through a number of metastable states.
