Název v původním jazyce

Dislocation structures in cyclically strained X10CrAl24 ferritic steel

Popis výsledku v původním jazyce

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 amplitudewere 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.
