Thermal and Structural Investigations of Cu-Al-Ni Shape Memory Alloys Irradiated Under Constant Gamma Radiation Dose

Abstract

In this study, shape memory alloys (SMAs) (wt%) Cu-13.0Al-4Ni and Cu-13.5Al-4Ni were used. 40 kGy radiation dose gamma was applied to the alloy samples. The effects of radiation dose on CuAlNi SMA samples were investigated. The effects on thermodynamic parameters were determined by differential scanning calorimetry (DSC). Microstructural examinations were performed by X-ray diffraction (XRD) and optical microscopy observations. Microhardness measurements of homogeneous and irradiated samples with 40 kGy radiation dose were compared.
