摘要	Mg-Y cast alloy shows excellent ductility (elongation to failure > 15%) compared with pure Mg and commercial Mg cast alloys. By monitoring the microstructure evolution during an in situ tensile test of a Mg-2.5 wt%Y alloy, we identify the activation of prismatic < c > slip, which is rare in Mg. Synchrotron X-ray micro-beam Laue diffraction ( mu -Laue) and transmission electron microscopy revealed the morphology of prismatic < c > slip bands and individual < c > dislocations. Density functional theory and molecular dynamics calculations indicate that solute Y can significantly reduce the stacking fault energy (SFE) along < c > direction on prismatic plane in Mg lattice and thus facilitate the nucleation of < c > dislocations during deformation. The presence of free < c > dislocations in the Mg lattice can also lead to nucleation of {10-12} twins even under unfavorable geometric conditions. (c) 2021 Chongqing University.
