Formation of dislocation cell substructure in face-centred cubic metallic solid solutions

Connection between deformation-induced dislocation substructures and martensite formation in stainless steel

“…According to Koneva et al [34], dislocation cell size decreases with increasing strain. According to them, the saturation value of the dislocation cell size in most fcc metals and alloys deformed at room temperature is slightly larger than 0.1 mm and typically lies in the range of 0.2-0.6 mm.…”

Dislocation configurations through austenite grain misorientations

“…According to Koneva et al [26], saturation value of dislocation cell size in most of the polycrystalline fcc metals and alloys deformed at room temperature is slightly larger than 0.10 µm and typically lies in the range of 0.20-0.60 µm. In austenitic stainless steels, various kind of dislocation sub-structures have been observed, depending on the nominal variation of strain amplitude imposed and the plastic strain accumulation inside the material.…”

Cellular dislocation substructure in polycrystals of FCC solid solutions: quantitative characteristics, laws of formation, and role in hardening

“…The behavior of h is more variable: 1) the width h decreases with increasing strain, 2) remains almost constant, and 3) increases with strain. In the Cu-Al and Cu-Mn solid solutions with the preset concentrations of Al and Mn, the third scenarium of the behavior is realized: D decreases and h increases with increasing strain [11,12]. When the Al and Mn concentrations in the solid solutions decrease, the third scenarium of the cell behavior is retained.…”

“…With increasing strain, the cell size decreases, and the wall width increases. Three patterns of the behavior of the cell size and wall width on the degree of plastic strain are well known (for example, see [11,12]). For all three patterns, D decreases with increasing strain.…”
