This work investigates the creep behavior of severely deformed commercial aluminum. The aluminum was processed by helical rolling (HR) and equal-channel angular pressing (ECAP) at room temperature. During these processes, equivalent strain up to about 4 imposed into as-received material. testing 200 °C revealed that HR ECAP significantly increased time fracture compared stress dependences showed value exponent n decreased with strain. stress-change tests states exhibited different recovery...
The health of the components that make up cables power lines, and hence their service life, is governed at micro level by changes in structure microstructure. In this paper, microstructure aluminum wires overhead transmission lines (without a steel core) different life from 0 to 62 years have been investigated quantitative techniques X-ray diffraction, diffraction back-scattered electrons, densitometric method. Elastoplastic properties tested acoustic-resonance A decrease Al material density...
The effect of wind on the wires overhead transmission lines leads to their vibration, as well oscillations different amplitudes. At places where wire is suspended, damage metal structure fatigue type occurs. This an excessive number vacancies, dislocations, grain boundaries and blocks compared equilibrium one. defective degrades in direction formation micro-gaps cracks. generation development zone occurs from surface wire. To prevent a rupture, it necessary monitor this during operation line...
Overhead power-transmission lines are one of the most important components modern infrastructure. Their service life is determined by state near-surface defect layers (NSDLs) wires constituting these lines. Both structure and microstructure NSDLs AAAC type (All Aluminum Alloy Conductor), which were in operation during 0 (new) to 62 years, investigated methods X-ray (XRD) electron back-scattering diffraction, optical microscopy, resistivity measurements, as well means densitometric acoustic...
