The superconductivity of BCC U Zr alloysSingle-phase, simple BCC structure, solid solution U Zr alloys were obtained by a rapid-quench-from-melt technique. Compositions range from 25 to 80 atomic percent Zr. Lattice parameters, atomic volumes and superconducting transition temperatures (between 0.6 ...
Superconductivity Electrical resistivity Crystal structure γ-U phase U-based alloys 1. Introduction The large interest in stabilization of U-based alloys with a cubic γ-U structure has came first from the viewpoint of metallurgy. In the late 1970s massive research programs were launched in USA ...
However, this aspect will need further consideration, more intensive analysis and understanding and deeply study the long-term consequences of using multi-elements with each having dif- ferent toxicity levels. Similarly, the field of high entropy polymer and superconductivity applications have started to...
The Nb-Zr system was reassessed based on calculated theoretical data and available thermodynamic and phase equilibria data. The Gibbs energies of the bcc and hcp solid phases were described using cluster expansion and cluster variation methods (CE–CVM) to model short-range ordering (SRO) in the ...
The crystal structures and properties of hafnium hydride under pressure are explored using the first-principles calculations based on density function theory. The material undergoes pressure-induced structural phase transitionI4/mmm→Cmma→P21/mat 180 and 250 GPa, respectively and all of these structur...
The authors report a theoretical calculation of the band structure and superconductivity of zirconium in the BCC phase under pressure. The effect of pressure on the band structure is obtained by means of the self-consistent linear muffin-tin orbital method. The superconducting transition temperature ...
