| 英文摘要 | Amorphization and nanohardness changes of SiC irradiated with 7 MeV Xenon ions at doses from 0.006 to 2 dpa were investigated. At a dose of 0.6 dpa, the results of Raman spectrum reveal the formation of Si-Si and C-C bonds within the SiC network while TEM results show the appearance of amorphous islands. The hardness of irradiated SiC is regarded as a combined result of covalent-bond damage and hardening effect of defects. In the low dpa regime (<0.06 dpa), the hardness of irradiated SiC increases with increasing dose, which is mainly caused by hardening effect. Up to 0.06 dpa, the hardening increases about 20.3%. And an equilibrium is reached between the covalent-bond damage and the hardening effect when irradiated SiC begins to amorphize (0.6 dpa). Above the dose of 0.6 dpa, the hardness decreases strongly due to the grievous covalent-bond damage. (C) 2014 Elsevier B.V. All rights reserved. |
