Stacking fault energies of seven commercial austenitic stainless steels

Atomic-scale plasticity in the presence of Frank loops

“…This potential predicts a stacking fault energy (SFE) of 44.4 mJ.m −2 , in the range of the highest values for SS at 600 K [29,34]. Note that the shear modulus in {111} plane of Cu is 41 GPa, whereas that of austenitic steel is 75 GPa.…”

Correlation Between Microstructure and Mechanical Properties Before and After Reversion of Metastable Austenitic Stainless Steels

“…In general, a lower 222 SFE makes dislocation cross-slip more difficult, result-223 ing in less dislocation mobility and promoting marten-224 sitic phase transformation. Using the equation suggested 225 by Schramm and Reed [31] (Eq. [2]), the SFE of this steel 226 results equal to 11.2 mJ/m 2 .…”

Thermally Stable Nanocrystalline Steel

“…The composition of Alloy 2 also aids this effect, since both nickel and aluminum lower the cross-slip energy in austenite while silicon increases it. [42,43] This reduces the rate of work hardening. Although the grain sizes in Alloy 2 appear to be larger than those typically associated with nanocrystalline bainitic steel, the transformation has taken place at a temperature consistent with such alloys in literature and the structure is certainly bainitic.…”
