“…To measure the temperature dependences of IF Q −1 (Т) and elastic modulus E(T), resonance vibrations at frequency f ≈ 2 kHz and the methods of a complete piezoelectric oscillator at frequency f ≈ 117 kHz and during alternative deformation ε ≈ 10 −6 in vacuum P ≈ 10 −3 Pa were used. The measurement error of IF determination was ΔQ −1 /Q −1 ≈ 10%, and the relative change in the elastic modulus was ΔE/E ≈ 0.1% [17][18][19][20][21].…”

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.

The existence and structure of the hierarchical and hydraulic relationship between the parameters of soil flow movement, the parameters of the closed collector-drainage network, and the parameters of channels and structures of drainage systems based on the application of the system methodology were determined. A physical model, a structural model, a mathematical model, and a hydraulic model of the drainage system were developed. By using these models, the principles of determining the parameters of the hydraulic characteristics of drainage or water supply (discharge, pressure, velocity, etc.) for all elements (drained massif of reclaimed field, collector and drainage network, open channels of the network, main channel, water intake) in the entire range of variation with possible consideration of changes in slopes were obtained. The considered approach will make it possible to evaluate the efficiency of the movement of the water flow simultaneously on all technical elements and the drainage system.
