Specimen dimensions and micro-hardness test measurements from gauge and grip places.Displacement controlled tensile ductile fracture and ULCF tests were performed in accordance with ASTM E606/E606M-12 [24] applying a Servohydraulic Biaxial Fatigue YC-001 Description testing Machine (manufactured by Walter Bai AG, Lohningen, Switzerland). The experimental set-up is shown in Figure three. In all ULCF testing, specimens have been subjected to straincontrolled completely reversed (R = -1) uni-axial cyclic strains at continual strain-amplitudes (/2) of 0.02, 0.03 and 0.04, respectively.
