A qualitative Assessment of the influence of gamma radiation and heating on aluminum using non-destructive examination

Abstract

The environmental degradation of metals can pose a significant challenge as it can reduce the effectiveness and lifespan of the equipment. As such, there is a growing need for new non-destructive testing methods that can help assess the behavior of materials in harsh environments. This research proposes the use of the non-destructive Scanning Contact Potentiometry (SCP) technique as a real-time monitoring system to control metals that are affected by external factors like gamma radiation and heating conditions. The SCP technique allows for the measurement of localized electro-physical signals on the surface of a material, providing insights into the material's behavior and characteristics. By using SCP as a real-time monitoring system, it is possible to detect changes in the material's behavior and take appropriate actions before any significant damage occurs. The study's findings highlight the effects of gamma radiation and heat on aluminum specimens. The accelerated growth of Al2O3 on the surface of aluminum specimens exposed to doses of up to 400 kGy and 1000 kGy underlines the importance of careful monitoring and maintenance to prevent metal degradation. Similarly, the concurrent changes in mechanical characteristics and oxide development at 150 °C reveal the need for effective management of temperature exposure in industrial settings. This research can contribute to the development of more effective strategies for managing and maintaining industrial equipment and designing new materials, with potential benefits for a wide range of industries.
