发帖数: 578 | 1 Mechanical properties (Vicker's hardness, Young's modulus, and fracture
toughness coefficient) have been studied for the three-dimensionally
polymerized, amorphous, and nanocrystalline diamond-plus-graphite composite
carbon phases prepared from fullerite C-60 by temperature treatment under
pressure. The hardness was found to increase gradually with the synthesis
temperature. The experimental values of hardness are well correlated with the
density of samples regardless of the phase structural nat |
