“…Up to date, numerous investigations have been performed on different class of austenitic steels in metastable state in order to achieve a deeper understanding and knowledge of the corresponding microstructural evolutions and their influences on the related mechanical properties [10,11]. However, appreciating all the previous attempts, the resultant peculiar strain hardening mechanisms are still not fully understood, and the extent and the sequence of various…”

“…[9] The applicability of this approach was discussed in detail by Geissler et al [10] If the influence of temperature is discussed (Figure 1(c)), the main influence is attributed to DG cfie (Figure 1(b)), whereas the other contributions show only a negligible temperature dependence. [6] With a low SFE, special deformation mechanisms in the austenite are activated that involves SF formation, [11][12][13][14][15][16][17] namely single-slip e-martensite formation and twinning. The dissociation width (d s ) of partial dislocations depends mainly on the shear stress component on the glide plane s zx and the SFE (c SF ) according to Byun.…”

“…A novel statistical method of AE signal categorization and recognition developed in [25] has been proven effective for real-time analysis of elementary deformation mechanisms in advanced materials including Mg alloys. The method was successfully tested and applied for discrimination between contributing deformation mechanisms such as dislocation slip, twinning and martensitic transformations from the AE signal at various stages of deformation in several materials [26][27][28][29][30].…”
