Pressure- and temperature-driven local structural stability and 5f/d hybridization in a metastable U–5.28 wt% Nb alloy
Metastable U–Nb alloys near 6 wt% Nb are U-rich actinide metallic materials in which Nb substitution, lattice distortion, vibrational stability and U-5f electron delocalization are strongly coupled. While high-pressure experiments and simulations have clarified important aspects of U–6Nb and ordered U–Nb compounds, the...
