Dislocation structures, effective and internal stresses of cyclic strained ferritic stainless steel
Original language description
The hysteresis loops of ferritic X10CrAl24 were digitally recorded and analysed in order to separate the effective and internal. By means of the ?Generalised statistical theory of the hysteresis loop? the average characteristics such as the effective elastic modulus Eeff, the saturated effective stress es and the probability density function f(ic) in relation to the number of cycles and ap, were determined. The cyclic plastic response of ferritic steel can be accurately describedd by this statistical theory (high es ≈ 255 MPa). As for the ferritic steel, the second local maximum of f(ic), was revealed. This phenomenon was discussed together with an observed dislocation arrangement by TEM methods, the orientation of crystals was determined by Kikuchi lines. The dislocation structures were studied in cyclical deformed polycrystalline ferritic stainless steel X10CrAl24 using transmission electron microscope (TEM). Specimens were strained in pl
