title: Delayed elastic effects in the glass ceramics Zerodur and ULE at room temperature.
abstract: The time-dependent phenomenon of delayed elasticity was studied at room temperature and is presented here for Zerodur and ULE. The effect is believed to be related to the alkali oxide content of the glass and to the rearrangement of the ion groups within the structure during stress.
