From: Nitrogen concentration driving the hardness of rhenium nitrides
Elastic properties of Re nitrides at 0 GPa.
Calculated (a) bulk modulus B (GPa), (b) shear modulus G (GPa), (c) Young's modulus E (GPa), (d) Poisson's ratio ν, (e) density ρ (g/cm3) and (f) Vickers hardness HV (GPa) of Re nitrides as a function of N concentration. The neighboring data points were connected by B-Spline to evaluate the changing trends. N-rich stoichiometries are highlighted by cyan shadows.
