Abstract
This study investigates γ-ray shielding properties of Ni–Ti–Hf shape memory alloys under uniaxial tension, correlating their mechanical properties with linear attenuation coefficients (LAC). We evaluated LAC (cm–1) values across various photon energies (E (MeV)), Ti:Hf ratio and APF, revealing an increase in LAC as (E, Ti:Hf, APF, LAC): (0.1, 2:3, 0.70, 32.5) to (0.1, 0:5, 0.74, 49.8) for samples subject to maximum deformation. The mechanical properties were also found to correlate very well with the γ-rays attenuation under optimal conditions. Notably, the plastic deformation of the alloys was found to enhance radiation shielding performance, with a significant reduction in γ-ray transmission (e.g., LAC = 1520 cm–1) observed in samples with higher mass recovery (e.g., 120%) rates post-deformation. These findings underscore the importance of maintaining alloy density and optimizing mechanical properties for effective radiation shielding in practical applications.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
