Temperature dependence of Young’s modulus and damping of fused cast AZS materials measured via high-temperature impulse excitation
Original language description
The impulse excitation technique (IET) is used to determine Young’s modulus and dampingfor commercial non-refractory alumina-zirconia-silica (AZS) materials containing zircon. Thetemperature dependence of Young’s modulus shows a steep decrease around 900 °C (duringheating) and a sharp minimum at 1000 °C, after which it increases again. The subsequent steepincrease above 1000 °C and the hysteresis during cooling show that this elastic anomaly isrelated to the monoclinic-to-tetragonal phase transition of zirconia. The temperaturedependence of damping shows a distinct damping peak in the range 300–400 °C, which is alsotypical for zirconia, and a steep increase in damping above 700–800 °C, which is lower thanthe onset of the steep Young’s modulus decrease by approximately 100 °C and does not exhibitany hysteresis. This high-temperature damping peak may be affected by the softening behaviorof a small amount of intergranular glass phase.
