英文摘要High-entropy carbide ceramics (WTiVNbTa)C-5 were prepared by spark plasma sintering and irradiated with 1.0 MeV C-ions at room temperature (RT) and 650 degrees C. Irradiation induced damage evolution and mechanical properties change were investigated. GIXRD and TEM results showed that the irradiation led to lattice expansion and micro-strain formation in the samples, which originated from the irradiation induced defects. The black-dot defects dominated in the damaged microstructure at fluence of 1E16 ions/cm(2) and transformed into dislocation loops and networks with the fluence increased at RT. Reduction of irradiation damage and formation of defect denuded zone were observed at 650 degrees C. No amorphization or void formation were observed for all samples after irradiation. The irradiation hardening was most severe at fluence of 1E16 ions/cm(2) and recovered at higher fluence or temperature, while the elastic modulus monotonically decreased. The correlation between microstructural evolution and mechanical properties response was discussed.
