摘要: Internal-friction data of calcium-doped Si3N4 polycrystalline materials that otherwise contain only SiO2 at grain boundaries were examined and compared with those collected on the same polycrystal in undoped state or doped anions (i.e., fluorine chlorine). Precise microstructural characterizations previously performed these enabled us to quantitatively evaluate inherent viscosity intergranular film through analysis anelastic internal-friction-peak components. The glass its scaling increasing calcium addition followed trend as bulk glasses chemical composition. Broadening internal-friction peak increased content material has also been rationalized according reduction activation energy for viscous flow glasses. present analysis, which is agreement our previous studies anion-doped Si3N4, demonstrated overall viscoelastic response mainly dictated by chemistry glass.
