Yield Symmetry and Reduced Strength Differential in Mg-2.5Y Alloy
In this study we report novel results obtained with an extruded fine-grained Mg-2.5 at.% Y alloy (FG Mg-2.5Y) exhibiting tension/compression yield symmetry and reduced strength differential, in addition to well-balanced strength and ductility. On the basis of detailed post-mortem transmission electron microscopy studies, atom probe tomography, and electron back-scattered diffraction (EBSD) characterization, we propose that the presence of a supersaturated solid solution strengthening for basal slip, and the enhanced activity of prismatic slip are the major causes for the unusual mechanical behavior.
