- •
Strain controlled fatigue tests were performed at ambient and elevated temperatures.
- •
Hysteresis loops were analyzed using generalized statistical theory of the loop.
- •
Dislocation structures were documented at both temperatures.
- •
Different surface reliefs were reported at ambient and at elevated temperatures.
- •
Effective stress and probability density distribution function were assessed.
