Abstract
The Bordoni relaxation appears only with a sufficient value of stress given by the Paré condition. We have made a direct measurement of internal stress in order to know its evolution during plastic deformation or annealing. This evolution is compared with the behaviour of the Bordoni relaxation : variation of the relaxation strength on the one hand and non linear properties on the other hand.
