In-situ, ex-situ EBSD and (HR-)TEM analyses of primary, secondary and tertiary twin development in an Mg–4 wt%Li alloy

Effect of age hardening on the deformation behavior of an Mg–Y–Nd alloy: In-situ X-ray diffraction and crystal plasticity modeling

“…Mg alloys, where TTWs grow readily and overtake the parent grains quickly [37,45,48,49], as has been reported in [37]. Figs.…”

The role of double twinning on transgranular fracture in magnesium AZ61 in a localized stress field

“…It is expected that the basal slip systems were partially activated in the localized stress field of the notch, although the grains exhibited a low Schmid factor. A significant activity of basal slip systems was previously shown for the grains and the primary f1 0 1 2g twins, which demonstrated a low Schmid factor [27,28]. However, in the current study, a low activity for the basal dislocations was detected via TEM.…”

A one-step mechanism for new twinning modes in magnesium and titanium alloys modelled by the obliquity correction of a (58°,a+ 2b) prototype stretch twin

“…For magnesium alloys, some histograms of misorientations extracted from EBSD maps reported in literature exhibit a peak corresponding to rotation of angle close to 56 and axis close to a + 2b (Nave & Barnett, 2004;Lentz et al, 2014), and Ostapovets et al (2017) The two possible obliquity corrections required to transform the (58 , a + 2b) stretch twin into a simple shear twin, by maintaining untilted (a,b) the plane (2112), and (c,d) the plane (2116). For a hard-sphere packing ratio ¼ ffiffiffiffiffiffiffi 8=3 p , this angle takes the value arccos 19=35 ð Þ'57:12 .…”
