Effects of Y on the Deformation Mechanisms of Extruded Mg-Y Sheets During Room-Temperature Compression

The effects of yttrium (Y) contents on the slip/twinning activity in extruded Mg-xY (x = 0-5, wt pct) sheets during room temperature (RT) compression were investigated quantitatively and statistically using a quasi-in-situ scanning electron microscope (SEM), electron backscatter diffraction (EBSD) combined with slip trace analysis and twin boundary misorientation analysis. No observable slip trace was found in the pure Mg, while the fraction of...
