摘要：
Beryllium oxide as a nuclear material has received renewed attention in recent years, and it is critical to investigate the irradiation behavior. The irradiation damage accumulation in beryllium oxide is investigated by molecular dynamics method. The evolution of defects and the degree of amorphization have been revealed as a function of dose at different irradiation temperatures. The dislocation induced by irradiation is obvious only when the irradiation temperature is above 873 K. A new cubic diamond structure appears at higher irradiation temperatures. Simulated XRD results are closely related to the degree of amorphization. In addition, the influence of irradiation damage on the compressive strength of beryllium oxide under different irradiation conditions is also studied.
