STUDIES ON ATTENUATION CROSS SECTION PARAMETERS OF SOME SHAPE MEMORY ALLOYS IN THE ENERGY RANGE 356 KEV– 1330 KEV
Journal Title: Indian Journal of Scientific Research - Year 2017, Vol 8, Issue 1
Abstract
Mass attenuation of five Shape Memory Alloy’s (SMA’s) such as Aluminum-Nickel (AlNi), Iron- Titanium (FeTi), Zinc Copper (ZnCu), Copper-Tin (CuSn), Stainless-Steel (Fe CrNiMo), has been calculated at 356 keV- 1330 keV photon energies and compared with Win XCOM data. It is observed that there is good agreement between experimental and theoretical values. The gamma rays were detected using NaI (Tl) scintillation detection system with a resolution of 8.2% at 662 keV. Other related parameters of Shape Memory Alloy’s (SMA’s) were determined experimentally and theoretically using the obtained values of mass attenuation coefficients and their variations with photon energy have been plotted. The transmission curve shows that the variation of all sample materials initially decreases with increasing photon energy. Investigated samples are good materials for biomedical, medical and biological, sensor/actuator, coupling and other applications.
