Cyclic hardening curves, the cyclic stress-strain curve and the fatigue-life curve were recorded. The dislocation recorded structure was studied using the technique of oriented foils in a 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 saturate. Low amplitude cycling results in the stabilized stress response. Surface slip markings and slip bands lying along {111} planes in the interior of the grains cut both channels and precipitates. Experimental results concerning the surface relief and the dislocation structure are used to discuss the stress-strain response"},{"@xml:lang":"sl","#text":"Cilindrične preizkušance, izdelane iz lite polikristalinične superzlitine Inconel 792-5A, smo izmenično deformacijsko utrujali pri 700 kompozitumC do porušitve. Določili smo ciklične krivulje utrjevanja, ciklične napetostno-deformacijske krivulje in krivulje dobe trajanja. Razporeditev dislokacij v mikrostrukturi smo opazovali in študirali s tehniko orientiranih folij v presevnem elektronskem mikroskopu (TEM). Za opazovanje površine reliefa prelomnih površin smo uporabili vrstični elektronski mikroskop (SEM). Značilnost deformacijskega utrujanja z veliko amplitudo je začetno utrujevanje, kateremu sledi nasičenje. Rezultat utrujanja z majhno amplitudo pa je stabilen napetostni odziv. Površinske drsne linije in zdrsela področja ležijo vzdolž ravnin {111}, v notranjosti zrn pa sekajo oba kanala in izločke.
