Surface Energies and Thermodynamic Phase Stability in Nanocrystalline Aluminas
Corundum, a-Al2O3, is the thermodynamically stable phase of coarsely crystalline aluminum oxide, but syntheses of nanocrystalline Al2O3 usually result in g-Al2O3. Adsorption microcalorimetry, thermogravimetric analyses, and Brunauer-Emmett-Teller adsorption experiments, coupled with recently reported high-temperature solution calorimetry data, prove that g-Al2O3 has a lower surface energy than ...

متن کاملFatigue Properties of Nanocrystalline Titanium
Fatigue resistance of nanocrystalline commercial pure titanium obtained by hydrostatic extrusion was investigated. Coarse grained titanium and Ti6Al4V alloy were used as the reference materials. The fatigue limit and fatigue life examined at constant stress amplitude, were found to increase significantly compared to those of the coarse-grained counterparts. It is suggested that the observed imp...
متن کاملA New Cubic Phase of Li3N: Stability of the N 3− Ion to 200 GPa
Diamond anvil cell experiments augmented by first principles calculations have found a remarkable stability of the N3− ion in Li3N to a six-fold volume reduction. A new (γ) phase is discovered above 40(±5) GPa, with an 8% volume collapse and a bandgap quadrupling at the transition determined by synchrotron x-ray diffraction and inelastic x-ray scattering. γ-Li3N (Fm3m, Li3Bi-like structure) rem...
متن کاملNew cubic phase of Li3N: stability of the N3- ion to 200 GPa.
Diamond-anvil cell experiments augmented by first-principles calculations have found a remarkable stability of the N(3-) ion in Li3N to a sixfold volume reduction. A new (gamma) phase is discovered above 40(+/-5) GPa, with an 8% volume collapse and a band gap quadrupling at the transition determined by synchrotron x-ray diffraction and inelastic x-ray scattering. gamma-Li(3)N (Fm3m, Li(3)Bi-lik...
