Damage analysis caused by 60Co ions in functionally graded materials

Abstract

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.
