N2 - Ultrasonic echography and a three-point bending creep test have been used to study the change in Young's modulus, E, and viscosity, η, during the structural relaxation of a SiYA1ON glass at 870°C, i.e., 40°C below the glass transition temperature. The increase in viscosity has been discussed and modelled in the frame of the fictive temperature theory and a relatively good fitting has been obtained between calculation and experimental results. In addition to the evolution of E and η, Raman scattering measurement are presented, which brings to light a microstructural change during the relaxation process.
