| Abstract | The rolled Mg-1.02Zn alloys with strong basal-textures and Mg-0.76Y alloys with weakened basal-textures were subjected to annealing in order to obtain different grain structures meanwhile keeping the textures nearly unchanged. Then tension testing and microstructure examination were applied to the Mg-1.02Zn and Mg-0.76Y alloys with different grain structures, aiming to validate the Hall-Petch relationship and related inner deformation modes. The tensile testing results show that the Mg-1.02Zn specimens exhibit two slope (k) of Hall-Petch relationships, that is, the coarse-grained ( > 49 mu m) specimens reveal an abnormally enhanced tendency of k (similar to 472 MPa mu m(1/2)) with increased strains while fine-grained (<= 49 mu m) specimens exhibit a slightly decreased tendency of k with increased strains. Contrastively, the Mg-0.76Y specimens follow a single slope of Hall-Petch relationship well in the grain regime with slightly declined k with increased strains. That could be attributed to the distinguished twinning responses and/or twinning-slipping interactions dependence of grain size in the studied alloys with different initial textures. |
