Interrupted tensile testing along the normal direction of a rolled AZ31 magnesium plate was conducted at various strain levels from 6% to 15.5%. Prior to deformation the specimens …
Dislocation slip and twinning are equally important in the plastic deformation of hexagonal close packed crystals. Basal slip and extension 10 1¯ 2< 1¯ 011> twins can be activated …

Abstract contraction twins that are commonly activated in α-titanium interact to each other and form three types of twin–twin junctions (,, TTJs) corresponding to the crystallography of …
Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1– 100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

Through in situ electron backscatter diffraction (EBSD) experiments, this paper uncovers dominant damage mechanisms in traditional magnesium alloys exhibiting deformation …
Fivefold deformation twins were reported recently to be observed in the experiment of the nanocrystalline face-centered-cubic metals and alloys. However, they were not predicted …
