The Impact of Gamma Radiation on Aluminum Alloy Thermal Conductivity Alumina Composite 6063

Abstract

The thermal conductivity of aluminum alloy 6063 alloy reinforced with alumina particles was studied. Aluminum alloy 6063 alloy matrix composites reinforced with varying weight percentage of alumina particles (0, 3, 5, 7) were prepared using the stir casting technique. Under normal circumstances (before to irradiation), the thermal conductivity tests were performed for every weight percentage. Because of the reinforcement material, we observe that the values of thermal conductivity drop as the weight % increases. Following exposure to gamma rays emitted from cesium, which has a half-life of 30.04 years and an emitted energy of 662 KeV, tests of thermal conductivity are conducted. When compared to thermal conductivity readings under normal circumstances, the results indicate a drop in thermal conductivity levels following irradiation. The thermal conductivity of the developed composites was analyses and compared with the matrix alloy. The experimental results showed that the composition ratio of reinforcement and gamma radiation influenced the structure of aluminum alloy 6063 alloy through homogeneously dispersed within the matrix and point defect. It can be leading to destroyed in thermal conductivity.
