This study investigates the thermal and oxidation behavior of nanocrystalline titanium nitride (TiN) particles subjected to varying doses of gamma radiation. The activation energy was analyzed during both heating and cooling processes, revealing a consistent activation value, with deviations at lower temperatures attributed to adsorbed impurities. Temperature-dependent heat flow measurements indicated significant deviations in heat flow within the 600K–850K range, correlating with the oxidation process observed in mass changes. The absence of such deviations during cooling further confirms that oxidation primarily occurs during heating, with gamma radiation enhancing reactivity. These findings highlight the complex interplay between radiation dose and thermal dynamics, contributing to a deeper understanding of TiN's performance in high-temperature applications.
