| Abstract Scope |
UTc<sub>3</sub> and URu<sub>3</sub> intermetallic alloys were prepared via vacuum arc-melting. After annealing for 10+ days in vacuum-sealed quartz tubes, cross-sections of the alloys were studied using scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS) to characterize the growth of microstructures and analyze the elemental composition of the alloys. Structural analysis was performed using powder x-ray diffraction (PXRD) on the polished cross section surface. The PXRD patterns were used to experimentally solve the samples’ solid-state structures. The resulting structural information was used to compare the solid-state structure of UTc<sub>3</sub> to the known Pm-3m structure of the URu<sub>3</sub> alloy. The magnetic susceptibility and the resistivity/conductivity of the samples were investigated using a Physical Properties Measurement System (PPMS). This study investigates the efficacy of ruthenium as a surrogate for technetium in metallic phases. It also provides valuable information regarding the structure and properties of uranium-technetium and uranium-ruthenium alloys. |
