“…The moment of separation of the dislocation segments from the stoppers can be determined by measuring the amplitude dependence of IF Q −1 (ε). To determine the variations in anharmonic effects, it is necessary to select high-fidelity measurement methods because these changes are small [8][9][10][11][12][13][14][15][16]. To set the spectrum of structural defects in the analysis of positions IF maximums -Q , M 1 the duration of relaxation time τ and their deposit in the attenuation of elastic vibrations can be used as a non-destructive IF method.…”

The simultaneous influence of hydrogen H and ultrasound deformation on internal friction Q −1 and dynamic elastic modulus E of intermetallic Ti3Al alloy after cutting and polishing were studied. The relaxation maximum of internal friction Q −1 M1 at temperature Т М1 ≈ 398 К, conditioned by the mechanism caused by reorientation interstitial atoms in dumbbell configurations H-H was discovered. Internal friction maximum Q −1 M2 in intermetallic Ti3Al at temperature T M2 ≈ 439 K was discovered with an activation energy H 2 = 0.86±0.1 eV. 2D and 3D atomic force microscopy microstructure images of Ti (VT8) alloy after mechanical and thermal treatment are presented. Strengthening of Ti alloys is related to the cooperation of dislocations with point defects.
