"Cylindrical specimens of cast polycrystalline superalloy Inconel 792-5A were cyclically strained under total strain control at 700 \u00B0C up to fracture. Cyclic hardening curves, cyclic stress-strain curve and fatigue life curve were documented. Dislocation structure was studied with the technique of oriented foils in transmission electron microscope. Scanning electron microscopy was used to investigate the surface relief. High amplitude straining is characterized by initial hardening followed by the tendency to saturation. Low amplitude cycling results in the stabilized stress response. Surface slip markings and slip bands lying along {111} planes in the interior of grains cut both channels and precipitates. Experimental results concerning the surface relief and dislocation structure are used to discuss the stress-strain response." .
