Abstract


Studies on bulk metallic glasses (BMGs) have grown considerably, especially in recent years, due to their noticeable properties such as high glass forming ability, corrosion resistance, large elastic limit, chemical, mechanical and magnetic properties. Among the known and studied samples of BMGs, Zr-based ones have been appointed as possible examples in biomaterial and structural material studies due to their good mechanical and corrosive properties and good biocompatibility. In this study, considering the importance of Zr-based BMGs, an investigation on their gamma-ray shielding properties have been done where five different samples have been utilized which are Zr51Al14.2Ni15.9Cu18.9, Zr52Al12.9Ni13.8Cu21.3, Zr53Al11.6Ni11.7Cu23.7, Zr54Al10.2Ni9.4Cu26.4 and Zr55Al8.9Ni7.3Cu28.8. Mass attenuation coefficients of the samples have been obtained by using Geant4 and XCOM between 0.1-15 MeV incident photon energy. Also, mean free path (MFP), half-value layer (HVL), tenth-value layer (TVL), effective atomic number (Zeff) and electron density (Neff) values of the samples in the given energy range have been obtained. Obtained results have been graphed for better visual comparison and interpretation.
