Abstract

Alterations in the structural composition of titanium carbide (TiC) nanocrystals induced by gamma radiation exposure were systematically investigated. A sample with an average grain size of approximately from 40 nm to 60 nm and possessing a cubic crystal structure (Fm3 m‾) was selected for the experiment. The X-ray diffraction method has been employed to analyze the changes that occurred after gamma radiation. The experimental results were theoretically analyzed employing the Rietveld, Scherrer, and Williamson-Hall methods, with subsequent comparisons conducted among them. Furthermore, the degree of amorphization induced by gamma radiation throughout the structure was quantified.
