Activated slip systems and microcrack path in LCF of a duplex stainless steel

Interpretation of annealing texture changes of severely deformed Al-Mg-Si alloy

“…In the present work, the slip systems in E-, Brass-, and, Cube-oriented grains were interpreted in relation to the accumulated frequency curves of Schmid factors (µ) which were estimated from EBSD data as shown in Fig. 4 [21]. These curves presented two slope changes of µ values, revealing three regions with a different number of activated slip systems, such as no slip, single slip, and multiple slip, as shown in Figs.…”

Strain incompatibilities and their role in intergranular cracking of irradiated 316L stainless steel

“…The slip direction was assumed to be whichever h1 1 0i direction on the {1 1 1} plane experienced the greatest resolved shear stress, and is indicated with the corresponding Schmid factor of the slip system. While this assumption is not necessarily always correct, as the stress state may be altered by neighboring grains, it is an assumption that is applied in practice when the specific slip that activated cannot be determined [18]. It is noteworthy that the Schmid factors given in Fig.…”

Effects of mean strain and tensile pre-strain on torsional fatigue behaviours of duplex stainless steel SAF2205

“…Investigations about the low cycle fatigue behaviours of DSS have been published mainly focused on the cyclic stress response, mechanisms of cracks nucleation and fatigue life [7][8][9][10][11][12]. PK Chiu et al [7,8] founded that a higher strain amplitude and tensile mean strain would promote the occurrence of strain-induced martensite (SIM) formation which could result in secondary hardening (SD).…”

“…However, information about the DSS LCF behaviours are too limited. The microcracks usually initiated along the extrusions in ferrite [10,11] and ferrite grain boundaries [12]. Moreover, the phase boundaries usually worked as an effective barrier for microcracks to further propagate.…”
