The internal friction at low temperatures has been measured on polycrystalline samples of -B, B 4 C, B 13 C 2 , and B 9 C. As the carbon deficiency increases in the boron carbides, the internal friction approaches that of amorphous solids. For comparison, the internal friction of amorphous B 9 C, pr
The vibrations of boron carbide B 13 C 2 have been studied by the valence force model. The 1560-cm ؊1 band is ascribed to the antisymetric stretching of the linear chain, and thereby it is IR active only. Large angle-bending forces of the carbon atoms are estimated to agree with the experiment. This
