Table 8 : Results data of fatigue test. Using different colours, in Fig.19 it has been reported the Wöhler curves of each specimen (3, 4, 5, 6). Following as it is indicated in [4-5], the number of the breaking cycles N r for a specific load has been obtained as the ratio between the energy parameter Φ and the stabilization temperature (the mean value of the detected ones).
