Hall–Petch relation for deformation twinning in solid solution magnesium alloys

The effect of grain size and alloying elements on the yield strength in compression was investigated using pure magnesium and its diluted solid solution alloys (Mg–Zn and Mg–Y alloys). The yield strength in compression was closely related to the {10–12} twinning, and followed the Hall–Petch relation in all the alloys. The value of σ0 increased in the following order, Mg–Y>Mg–Zn>pure magnesium, indicating solid solution strengthening; however,...
