title = "Thermal and chemical stability of the {\ss}-W2N nitride phase",
abstract = "Pure Be, W and Be:W mixed coatings with nominal compositions of (5:5) and (1:9) were deposited on silicon plates and implanted at room temperature with 30 keV N + ions with fluences up to 5e17 ions/cm 2. Ion beam and X-ray diffraction analysis evidenced the formation of the α-Be 3N 2 and β-W 2N nitrides. The identified tungsten nitride phase evolves from a BCC W lattice to a BCC W(N) solid solution after irradiating at a fluence of 1e17 N +/cm 2 and to the compact FCC β-W 2N structure at 5e17 N +/cm 2. Thermal stability of β-W 2N was investigated by annealing the coatings for 1 h up to 1073 K. The results point to the release of non-bonded nitrogen solute in β-W 2N over the annealing range and to the thermal stability of the nitride phase up to 1073 K. ",
