Uranium carbide oxidation from 873 K to 1173 K

Oxidation of UC was studied from 873 to 1173 K in air and in 10 Pa oxygen using a High Temperature Environmental SEM (HT-ESEM). Conversion to U3O8 improved when using 873 K as the oxide product was a fine powder. At higher temperatures (973 K to 1173 …

Modelling and experimental analysis of the effect of solute iron in thermally grown Zircaloy-4 oxides

Simulations based on density functional theory (DFT) were used to investigate the behaviour of substitutional iron in both tetragonal and monoclinic ${\\text{ZrO}\\_2}$. Brouwer diagrams of predicted defect concentrations, as a function of oxygen …

In-situ digital image correlation for fracture analysis of oxides formed on zirconium alloys

Repeated breakdown of the protective oxide layer can be a key factor in the oxidation of zirconium alloys. Hence, accurate measurement of the oxide fracture strength is crucial for simulating the oxidation of these alloys. High resolution digital …
