| 摘 要： | 金属氢化物(MH_x)应用于反应堆中子慢化剂、激光离子源片材料、中子发生器用靶时,会经历极端非平衡束流的辐照。本工作提出利用TEMP-6型强流脉冲离子束装置产生的强流脉冲离子束(high intensity pulsed ion beam,HIPIB)辐照Ti D_2膜,评估极端束流对膜力学性能的影响因素和影响程度。采用涂层附着力自动划痕仪、维氏显微硬度计对原始和辐照后的Ti D_2膜进行测试分析。研究结果发现:多次HIPIB的辐照效应导致膜面重熔再结晶,使其内部结构趋于更加致密化和平整化,能降低材料的摩擦系数并在一定程度上提高其初始临界载荷;D的释放有助于膜面韧性、显微硬度的提高,从而减轻了其塑性形变程度。

| Abstract: | Metal hydride (MHx) is typically under extreme non-equilibrium irradiations when used as a neutron moderator in nuclear reactor, an ion source in laser, a target material for neutron generator, and other devices. This work proposes using an extreme non-equilibrium high intensity pulsed ion beam (HIPIB) to evaluate the effects on mechanic properties of TiD2 film under non-equilibrium irradiations. Both microscratch and microhardness were measured for the original and irradiated samples. Results reflect that frictional coefficient on the surface of scratch test is reduced under repetitive irradiations, and repeated melting of the surface layer makes the scratch revealing a more smoothed and densified texture, and the release of D can also improve both of its hardness and toughness, alleviating the plastic deformations. |
