摘要

通过在 AA6082 基体中添加不同比例（0-50%）的 BC、TiO 和 BC+TiO 陶瓷材料，制备了功能分级复合材料/混合材料（FGCM/FGHCM）。使用 SRIM/TRIM Monte Carlo 仿真软件分析了 Co 离子（1.173-1.1332 MeV）对材料造成的破坏。在模拟过程中，获得了目标材料原子的以下数据：离子分布、目标电离、总位移、表面结合能、晶格结合能和位移能。在所研究的四种材料中，离子范围值最高的是 AA6082，为 8550 Å。由于结合能较高，BC 增强 AA6082+（0-50%）BC FGCM 的空位最少，为 4782 个/离子。

Damage analysis caused by 60Co ions in functionally graded materials

Functionally graded composite/hybrid materials (FGCM/FGHCM) were produced by adding BC, TiO, and BC+TiO ceramic materials at various ratios (0–50%) into the AA6082 matrix. The analysis of the damage caused by Co ions' (1.173–1.1332 MeV) on the material was examined using the SRIM/TRIM Monte Carlo simulation software. In the simulation, the following data regarding the atoms of the target materials were obtained: ion distribution, target ionization, total displacements, surface binding energy, lattice binding energy, and displacement energy. Among the studied four materials, the one with the highest ion range value was found to be AA6082 with 8550 Å. TiO was found to be the reinforcement material that reduced the ion range the most in the material. Due to its high binding energy, BC reinforced AA6082+(0–50%) BC FGCM was found to have the least vacancy with 4782/ion.
