“…9 shows a bright field TEM image with bimodal microstructure, and no sign of twinning was observed. This contrasts reports of twinning in other nanostructured magnesium alloys with higher alloying contents [29,48,49]. The stress required for twin nucleation increases substantially with reducing grain size to the nanometre scale, thereby reducing the occurrence of twinning as grain size is reduced [45].…”

“…Recently molecular dynamics (MD) was employed to reveal the deformation mechanisms in Mg NC materials [5,6,7,8,9,10,11,12]. Kim et al [5,6] discuss the existence of basal and non-basal slip systems and twinning systems in the preferentially oriented columnar grains in the NC Mg during creep.…”

“…They also studied the effect of grain size on deformation in randomly oriented 3-D NC Mg [7]. The recent paper by Moitra [8] also discusses the effect of grain size on the microstructural properties of pure Mg. Pozuelo [12] et al investigated how twins influence deformation in Mg-Al alloys. Bhatia et al discussed the creep behavior in Mg-Y alloys [9].…”

“…Existing experiments showed that NT structure in magnesium alloys could be obtained by applying a tensile loading or using surface mechanical attrition treatment (SMAT) [ 8 , 9 ]. Recently, Pozuelo et al [ 10 ] proposed a comprehensive approach to form NT structure in NC Mg-based alloys.…”
