The effect of oxygen impurities on the stability and structural properties of vacancy-ordered and -disordered ZrC<sub><i>x</i></sub>
Theresa Davey, Ying Chen
Abstract
≤ 1) phases was found to decrease with increasing oxygen concentration, which can be attributed to the different ionocovalent nature of the C-Zr and O-Zr bonds. The volume of the vacancy-ordered phases within the expected oxygen solubility limit is greater than the disordered phase of the same composition, which is explained in terms of the relative bond strengths surrounding different vacancy distributions.
