Abstract

Abstract : This study aims to investigate the ability of as-prepared PbSn3 Sb x ( x = 0.0, 0.5, 1.5, and 2.5 wt.%) alloys for shielding against gamma-rays, the relationships between the mechanical properties and gamma-ray shielding parameters for four types of alloys have been studied and analyzed. Gamma-ray interaction with the as-prepared alloys has been discussed mainly in terms of total mass attenuation coefficient ( µm ), linear attenuation coefficient ( µ ), half value layer (HVL), and mean free path ( Xm ). From X-ray analysis, a crystalline intermetallic compound phase of SnSb is detected. The formation of the intermetallic compound phase and refinement of evaluated particle size causes a pronounced enhancement in internal friction, dynamic elastic modulus, and microhardness indentation. Attenuation shielding parameters of as-prepared alloys with free antimony are measured and calculated. It is noticed that the obtained results showed desirable values of shielding parameters. Mechanical properties and Vickers microhardness, Hv are critically evaluated and sensitive to changes in temperature and Sb antimony additions. Thus, the study indicates that 2.5 wt.% Sb alloy sample has a distinguished protection ability to attenuate the gamma-ray radiation. It can be concluded that the Sb additive for this type of binary alloys at content 2.5 wt.% can help to increase the shielding gamma-ray performance.
