| Description
| - Transmisním elektronovým mikroskopem byly studovány dislokační struktury v polykrystalické korozivzdorné feritické oceli X10CrAl24 cyklicky deformované s konstantními amplitudami plastické deformace.Použitím techniky orientovaných fólií byly určeny prostorové uspořádání dislokací.Byly stanoveny charakteristické typy dislokačních struktur.Typické dislokační struktury se skládaly z nepravidelného uspořádání převážně šroubových dislokací, pro nejnižší amplitudy deformace, dále z žilové a stěnové, které byly protínány téměř žebříkovou strukturou, pro střední amplitudy deformace,a převážně ze stěnové labyrintové a buňkové struktury pro největší amplitudy deformace.Byl kvantitavně vyhodnocen jejich relativní podíl v zavoslosti na deformaci. Zvláště byla věnována pozornost cyklickému změkčení, které bylo diskutováno z hlediska specifických vlastností šroubových dislokací v b.c.c. strukturách a lokalizací cyklické plastické deformace do perzistentních skluzových pásů.

- Dislocation structures in polycrystalline X10CrAl24 ferritic stainless steel cyclically strained with constant plastic strain amplitude to failure were studied using transmission electron microscopy. The spatial arrangement of dislocations in the individual grains was determined using the oriented foil technique. The characteristic types of dislocation structures were determined. The typical dislocation structures consisted of a random arrangement of mostly screw dislocations for the lowest strain amplitudes,veins and walls intersected by ladder-like structure for medium plastic strain amplitudes and predominantly wall, labyrinth and cellular structures for the higheststrain amplitudes. Their relative fractions dependent on the applied strain amplitude were quantitatively evaluated.Special attention was paid to cyclic softening which is discussed in terms of specific properties of dislocations in a b.c.c. structure and the localization of cyclic plastic strain to persistent slip bands.
