In this study, the radiation shielding properties of AA6061 and its composite material reinforced with 5% TiB2 ceramic were investigated using the Phy-X/PSD program for gamma 60Co isotope gamma radiation (1173 keV). Key shielding parameters such as the linear attenuation coefficient (LAC), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), and effective conductivity (Ceff) were analyzed. The results indicate that the LAC values for AA6061 and AA6061 + 5% TiB2 were 15.394 cm−1 and 15.874 cm−1, respectively, while the HVL values were determined as 0.045 cm and 0.0436 cm, respectively. The findings suggest that the TiB2 reinforcement enhances radiation attenuation efficiency. Additionally, SRIM/TRIM simulations were performed to examine the effects of gamma 60Co isotope irradiation on these materials at 1173 keV, focusing on mechanisms such as ionization, phonon interactions, and material damage analysis. The total damage values were found to be 16.73 for AA6061 and 16.59 for AA6061 + 5% TiB2, indicating that the composite structure experiences slightly less damage due to the presence of TiB2. The combined results from Phy-X/PSD and SRIM/TRIM analyses demonstrate that the addition of 5% TiB2 enhances the radiation absorption capacity of AA6061, making it a promising candidate for applications requiring improved radiation shielding performance.
