Effects on Structure and Properties of Zr53Al23.5Cu5.9Co17.6  Metallic Glass Irradiated by High Intensity Pulsed Ion Beam

  • 摘要: 利用强流脉冲离子束(High Intensity Pulsed Ion Beam,HIPIB) 模拟核聚变装置中的瞬态高热负荷环境,离子束成分为Cn+(70%) 和H+(30%)、加速电压为250 kV,研究金属玻璃Zr53Al23.5Cu5.9Co17.6 和金属W在不同参数的HIPIB 辐照下结构和性能的变化规律以及损伤行为。XRD显示辐照后金属玻璃均保持非晶相为主要结构,金属W中有应力产生。SEM观察在辐照次数为3 和10 次时金属玻璃和金属W表面都没有明显的辐照损伤现象;当辐照次数增加到100 和300 次后,金属玻璃表面出现了花瓣状形貌和小球,金属W表面则出现了裂纹。纳米压痕仪测量辐照后金属玻璃的表面纳米硬度随辐照次数的增加逐渐降低。Zr 基金属玻璃具有较好的耐辐照性能,对HIPIB 辐照时产生强的热应力的缓冲能力比金属W好.

The ion beam was mainly composed of Cn+(70%) and H+(30%) at an acceleration voltage of 250 kV. We investigated the changing rule of the structure and performance and damaged behavior of metallic glassZr53Al23.5Cu5.9Co17.6  and W metal under different number of pulses.
