| 中文摘要 | We report depressurization amorphization of single-crystal boron carbide (B(4)C) investigated by in situ high-pressure Raman spectroscopy. It was found that localized amorphization of B(4)C takes place during unloading from high pressures, and nonhydrostatic stresses play a critical role in the high-pressure phase transition. First-principles molecular dynamics simulations reveal that the depressurization amorphization results from pressure-induced irreversible bending of C-B-C atomic chains cross-linking 12 atom icosahedra at the rhombohedral vertices. |
