Sažetak
Dilatometric experimental technique /1/ represents specific method with which it is possible to observe the kinetics of low-temperature relaxation of amorphous metallic ribbons. The technique requires exceptional accuracy so that the contraction of samples under the influence of rearrangement of atoms which changes the excess of free volume can be observed.
The development of this technique required a series of additional corrections to increase the precision of measurements and to achieve a realistic picture of experimental results. This paper describes the improvement of this experimental technique in terms of comparisons of the results obtained. In the paper we present the measurement of the length of amorphous system Co₇₈Nb₁₆B₆ using the new improved experimental technique.
