Formatted abstract
Solid solution effects on the hardness and flow stress of single phase polycrystalline Mg-Sn binary alloys have been studied for alloys with Sn content ranging from 0.6 to 2.5 at.% (2.9 to 11.1 wt.%). The hardness at room temperature was found to increase monotonically with Hv1 ( = 31.1 + 7.05Sn (at.%). Sn was found to have a significantly higher strengthening effect than Al but lower than Zn, Gd, and Y. After correction for grain size effects, the (0.2%) proof strength was found to increase linearly with c2; where c is the solute concentration (at.%). The observed strengthening was found to be dominated by solid solution strengthening of the basal plane. Additionally, it is suggested that the formation of regions of short range order may account for a significant portion of the strengthening as well as the high strengthening rate.
