Thermally Activated Slip in Rare Earth Containing Mg-Mn-Ce Alloy, ME10, Compared with Traditional Mg-Al-Zn Alloy, AZ31

The thermally activated deformation of textured Mg alloys is evaluated using repeated stress relaxation tests analyzed with the assistance of elasto-viscoplastic self-consistent (EVPSC) polycrystal modeling. The data, presented in a Haasen plot, suggests that the superposition of at least two mechanisms controls the thermally activated glide of dislocations in both a rare-earth containing alloy, ME10, and the conventional alloy, AZ31: forest...
