Isochronal annealing treatments

The isochronal annealing treatment of the deformed samples started at 473K just after sample preparation without any additional heat treatment (figure 3). 

In order to study the annealing behavior of the hydrogen-related defects, infrared absorbance spectra were recorded at 10 K after each step in a series of isochronal heat treatments (annealings) at temperatures in the range 400-1200 °C. The annealings were performed in a furnace purged with argon gas and the duration of each treatment was 30 min. 

In Figure 1 in addition to isochronal measurements plateau values of a small step annealing treatment (order-order relaxations) are given for a comparison (o). These points reflect a variation of equilibrium state of LRO-parameter with temperature.
